A propane hose and regulator for a propane tank can make an RV cooking setup more flexible, but the fitting must match both the appliance and the supply. RV owners often need extra length to separate a grill from the trailer, while grill owners replacing a damaged assembly need the correct thread size and hose length.
A quick-connect fitting snaps directly into a compatible RV propane supply without tools. A 3/8-inch flare fitting, by comparison, uses a threaded connection designed for many freestanding grills, fire pits, and heaters. The seven options below cover RV hookups, dual-appliance arrangements, Blackstone griddles, and common grill replacement assemblies.
The Lineup, Simplified
Stanbroil 12FT RV Propane Hose and Elbow
Dunkive 12FT RV Propane Hose Y Splitter
Rushare 12FT Blackstone Griddle Hose
CALPOSE 6FT Propane Regulator and Hose
Rushare 2FT Universal 3/8-Inch Grill Regulator
CALPOSE 28IN Weber Hose and Regulator Kit
CALPOSE 2FT Regulator and Gauge Hose for Blackstone
A 12-foot line gives you room to place a tabletop grill away from the RV while keeping it connected to a low-pressure propane supply. The Stanbroil assembly combines a flexible rubber hose, solid brass fittings, and a 90-degree-style elbow for a Blackstone camping grill.
Its 1/4-inch quick plug snaps into a compatible RV connection without tools, while the opposite end terminates in the elbow adapter. That makes this a focused choice for RV owners who want a longer reach rather than a dual-appliance distribution system.
A Few Strong Suits
- Twelve feet of flexible hose adds useful reach around an RV or campsite.
- The quick-connect end supports tool-free attachment to a compatible supply.
- Rubber construction and brass fittings suit repeated outdoor cooking setups.
- The elbow adapter gives the grill connection a compact orientation near the trailer.
Points To Note
- The elbow is intended for a compatible Blackstone-style connection, so check the receiving fitting before ordering.
- Twelve feet takes more room to coil and store than the shorter grill assemblies in this lineup.
Quick Facts
Made For RV Cooking
You gain the most from this option when your RV powers a compatible Blackstone tabletop grill and the trailer wall sits close to your cooking area.
A Better Fit Elsewhere
The Dunkive 12FT RV Propane Hose Y Splitter serves you better when you need two 1/4-inch appliances connected to one RV supply.
Two appliances sharing one RV propane supply is the defining feature here. The Dunkive set includes two 12-foot hoses and a Y-shaped splitter with two 1/4-inch quick-connect outlets and one 1/4-inch male supply connection.
That arrangement suits an RV patio with a grill and fire pit, or a campsite where you want the appliances separated from the trailer. Compared with the Stanbroil single-hose setup, this kit prioritizes distribution and reach over a dedicated griddle elbow.
The Upside
- Two 12-foot hoses give both connected appliances room to sit apart.
- The brass splitter provides a central connection for two 1/4-inch appliances.
- You can use one RV supply for a grill, fire pit, camp stove, or similar appliance.
- A rubber dust cap helps shield one splitter connection.
- Quick-connect fittings remove the need for tools during setup.
Things To Consider
- Both appliances and the RV supply must use compatible 1/4-inch quick connections.
- Two long hoses create more cable and hose than you need for a single-appliance setup.
Who Will Love This
You benefit most with two low-pressure RV appliances that each have a 1/4-inch male quick-disconnect fitting.
Another Choice May Suit
The Stanbroil 12FT RV Propane Hose and Elbow is the simpler fit for one compatible Blackstone griddle beside an RV.
Blackstone tabletop griddles come in sizes and fittings that make a dedicated hose easier to select. The Rushare assembly is made for 17-inch and 22-inch models, joining the griddle to an RV low-pressure propane supply.
The 12-foot hose provides enough reach for an outdoor cooking area away from the trailer, while the 90-degree elbow helps direct the connection. Its three-layer construction adds another material layer compared with the standard rubber hoses in several regulator kits.
Where It Delivers
- Specific fit for 17-inch and 22-inch Blackstone tabletop griddles.
- Twelve feet of reach supports outdoor RV and camping arrangements.
- Solid brass fittings pair with a weather-resistant three-layer hose.
Small Caveats
- The stated compatibility covers 17-inch and 22-inch tabletop griddles, not larger 28-inch or 36-inch models.
- You still need a compatible RV quick connection and a matching griddle-side fitting.
Feature Snapshot
Right Fit For Griddles
You get the cleanest match when your outdoor cooking appliance is a 17-inch or 22-inch Blackstone tabletop griddle powered by an RV.
Where Another Pick Shines
The CALPOSE 2FT Regulator and Gauge Hose for Blackstone suits you better with a 28-inch or 36-inch griddle that uses a 3/8-inch flare connection.
Six feet gives a grill enough separation from its propane cylinder without turning the hose into a bulky RV line. The CALPOSE assembly combines a QCC cylinder adapter, a regulator, and a 5/16-inch hose with a 3/8-inch female flare fitting.
A flare fitting uses a threaded, sealed connection, making this option more familiar for common Weber, Char-Broil, Nexgrill, Monument, Dyna-Glo, and Brinkmann appliances. The regulator is specified to deliver 11 inches of water column and includes excess-flow protection.
Bright Spots
- Six feet provides useful placement flexibility around a patio grill.
- The hose and regulator arrive as one connected assembly.
- A broad fit list covers many grills, heaters, stoves, and fire pits.
- The regulator maintains the specified outlet pressure during normal propane use.
Practical Considerations
- Your appliance needs a 3/8-inch male flare fitting for the hose to connect.
- Six feet may be short for a grill positioned several yards from the cylinder.
Core Details
Best Suited To Patios
You get the most flexible use from this option with a standard 3/8-inch flare grill or fire pit placed within six feet of its cylinder.
Look Elsewhere When
The Rushare 2FT Universal 3/8-Inch Grill Regulator is the tighter choice when your grill sits close to the propane supply and needs a compact replacement.
A short regulator hose works well when the grill or fire pit remains close to the propane cylinder. This Rushare option combines a two-foot rubber hose with solid brass fittings and a QCC-1 cylinder connection.
The 3/8-inch female flare end fits appliances with the matching male flare inlet, including many Weber, Blackstone full-size griddle, Char-Broil, Royal Gourmet, Nexgrill, and Brinkmann models. For most patio layouts, the compact length is easier to manage than a 12-foot RV hose.
What It Does Well
- The two-foot length keeps the propane line close to the appliance.
- Brass fittings and weather-resistant rubber support outdoor use.
- One regulator covers many common grill brands and fitting styles.
Less-Strong Areas
- Do not use this assembly with a propane appliance rated above 80,000 BTU, a measure of heating capacity.
- Two feet offers little repositioning, so your grill and cylinder must share a close storage area.
Who Should Grab It
You benefit most when replacing a compact grill regulator for a common 3/8-inch appliance that remains beside its propane cylinder.
Reach For A Different Pick When
The CALPOSE 6FT Propane Regulator and Hose gives you more placement room when the appliance needs to sit several feet from the cylinder.
A model-specific replacement can make sense when your Weber grill uses the same connection style as the original assembly. This 28-inch CALPOSE kit fits the Spirit, Spirit 210, 310 and 320, Spirit II 210, 310 and 320, Genesis 300, and Summit 400 and 600 ranges.
Its 3/8-inch flare connection follows the same general fitting format used by Weber part 7627. Brass fittings and a rubber hose handle the outdoor setting, while precision threading supports a close, orderly connection to a compatible inlet.
What Pays Off
- The listed Weber model coverage gives you a clear compatibility target.
- The 28-inch length offers more positioning room than a two-foot regulator hose.
- Brass fittings and rubber construction suit routine outdoor grilling.
Details To Watch
- The listed fit centers on Weber models, so other grill brands require separate confirmation.
- Twenty-eight inches remains a compact line and may not reach around a large patio table.
Technical Highlights
Built With In Mind
You gain the closest fit with a listed Weber Spirit, Genesis 300, or Summit model that uses the standard 3/8-inch flare connection.
Swap It Out When
The CALPOSE 6FT Propane Regulator and Hose serves you better when your grill uses a compatible 3/8-inch fitting and needs a much longer line.
A visible gauge adds a useful check to a compact regulator assembly. This CALPOSE kit pairs a two-foot, 5/16-inch hose with a QCC cylinder adapter, a 3/8-inch female flare fitting, and a gauge for monitoring the line.
The listed applications include 28-inch and 36-inch Blackstone griddles, Weber grills, fire pits, camp stoves, heaters, water heaters, and other appliances with a 3/8-inch male flare inlet. The regulator is specified to provide 11 inches of water column with excess-flow protection.
Standout Benefits
- The gauge gives you a visible way to check line pressure.
- Two feet keeps the assembly compact beside a griddle or fire pit.
- The fitting supports a wide range of common propane appliances.
- The QCC adapter and regulator are combined in one setup.
Possible Compromises
- Your appliance must have a 3/8-inch male flare connection.
- The two-foot hose provides little movement for a griddle positioned away from the cylinder.
Key Product Details
Made For Monitoring
You benefit most when a Blackstone griddle or other 3/8-inch appliance sits close to its cylinder and you want visible pressure information.
Consider Something Else When
The Rushare 12FT Blackstone Griddle Hose is the stronger choice for a 17-inch or 22-inch tabletop griddle using an RV supply.
What to Check Before Connecting Your Propane Line
Identify the Supply Connection
RV systems commonly use a 1/4-inch quick connection, while many freestanding appliances use a 3/8-inch flare inlet. A quick plug snaps into the supply, whereas a flare fitting threads onto the appliance and uses a seal at the joint. Measure or identify both ends before choosing a hose, because two similar-looking propane connections may use different sizes.
Match the Appliance Inlet
Your grill, griddle, heater, or fire pit needs a connection that matches the hose or regulator. The Stanbroil and Dunkive options center on 1/4-inch quick-connect equipment, while the CALPOSE and Rushare regulator kits use 3/8-inch female flare fittings. Check the appliance manual and your existing connector before arranging a new assembly.
Choose Length for the Layout
Measure the distance from the propane supply to the appliance and leave enough slack for movement. A 12-foot hose works for separated RV cooking areas, while two to six feet keeps a patio setup easier to organize. Longer lines also require more space for coiling and storage.
Two Details That Change the Fit
Common Shopping Slip Ups
A matching hose length can still have the wrong connection at one end, so verify the RV outlet and appliance inlet separately. Also consider storage, since a long outdoor hose takes more room than a compact regulator kit.
What The Higher Tier Buys
The more specialized options in this group add functions such as a Y splitter, visible gauge, or a three-layer hose. Those features help when your setup serves multiple appliances, benefits from pressure monitoring, or uses a specific griddle connection.
Frequently Asked Questions
How do I know which propane connector you need?
Check the RV supply fitting and the appliance inlet before selecting a hose. A 1/4-inch quick plug suits compatible RV systems, while a 3/8-inch flare fitting suits many freestanding appliances.
Are RV quick-connect and grill flare fittings interchangeable?
They serve different connection formats and cannot be treated as direct substitutes. Verify both ends of your existing setup and follow the fitting instructions supplied with the appliance.
How long should a propane hose be for a grill?
Measure from the propane source to the intended cooking position and add modest slack. Long RV lines offer placement flexibility, while shorter regulator hoses keep a patio setup compact.
Can one propane source operate two appliances?
A Y splitter can route one supply connection to two compatible appliances. You need suitable 1/4-inch quick connections on both devices, and the arrangement must follow the operating guidance for your RV system and appliances.
Does a regulator hose include a pressure gauge?
Some assemblies include a gauge while others do not, so check the product details before ordering. A gauge gives you a visible reading from the regulated propane line.
Closing Remarks
The right propane hose and regulator depends mainly on the connection format, appliance inlet, and required reach. RV quick-connect systems favor the Stanbroil and Dunkive kits, while common grill and griddle applications are better served by the listed 3/8-inch flare assemblies. Confirm both ends before ordering, then choose the length that suits your actual cooking area.
