FAQ

This item matches part number F273684. If you are replacing an existing hose assembly, confirm that your current part number and end connections match before ordering.
This is a 12-foot propane hose with an integrated regulator used to supply propane from a tank to compatible gas-fired equipment. Hose-and-regulator assemblies like this are commonly used on heaters, outdoor cooking equipment, and other propane appliances that require regulated fuel pressure.
Common signs include cracking or stiffness in the hose, the smell of propane near the line or fittings, visible damage at the connector ends, poor burner performance, difficulty maintaining flame, or a regulator that no longer delivers steady gas flow. If there is any sign of leakage or hose deterioration, replace the assembly rather than trying to repair it.
Check three things: the part number (F273684), the hose length you need, and the exact tank-side and appliance-side fittings on your equipment. The replacement must match both connection types and be suitable for propane use with your specific appliance. If your original assembly includes a regulator, the replacement should also include the correct regulator style.
Installation is usually straightforward and often takes about 10 to 20 minutes. In most cases you will need basic hand tools such as adjustable wrenches. Shut off the propane supply first, work in a well-ventilated area, avoid twisting the hose during installation, and perform a leak check with soapy water on all connections before use.
The most common causes are age-related rubber deterioration, UV and weather exposure, abrasion, kinking, contamination inside the regulator, damaged sealing surfaces, and stress from repeated bending at the fittings. Outdoor storage and long periods of non-use can also shorten service life.
Inspect the tank valve, appliance inlet, and all threaded fittings for dirt, corrosion, worn sealing surfaces, or thread damage. Make sure the old hose did not fail because of rubbing, heat exposure, or improper routing. After installation, open the tank slowly and test every connection for leaks before lighting the appliance.
