A full 144 inches of high-pressure propane line designed for the supply side of your RV LP system -- between the tank and regulator, or feeding a high-pressure appliance direct. Solid brass swivel fittings on both ends make connection straightforward and secure.
The Suburban Mfg 523012 is a 144-inch (12-foot) high-pressure LP gas hose built for use on the high-pressure side of an RV propane system -- the supply run from a propane tank to the first-stage regulator or to a high-pressure appliance inlet. At 12 feet, it provides significantly more reach than standard 6- or 8-foot hoses, useful when routing around compartment walls, slideouts, or when positioning an external tank away from the rig.
One end terminates in a 3/8" female NPT thread fitting for connection to a standard high-pressure propane source or appliance inlet. The other end is a 3/8" female flare swivel fitting, which rotates freely during installation to prevent hose twist and allow proper alignment without cross-threading. Both fittings are brass construction, compatible with the LP gas environment and resistant to the corrosion that degrades zinc or pot-metal fittings over time.
Full 12 feet of hose gives you the reach to route propane supply lines through awkward compartment paths or to position portable tanks at a safe distance.
The 3/8" female flare swivel on one end rotates freely so you can make up the connection without twisting or stressing the hose body.
Designed for the supply side of the LP system -- the high-pressure run before the first-stage regulator steps gas down to working pressure.
Both end fittings are solid brass, compatible with LP gas service and resistant to corrosion in outdoor and under-chassis environments.
This hose is intended for the HIGH-PRESSURE side of the LP system -- the run from the propane tank outlet to the inlet of an automatic changeover regulator or first-stage regulator. It is not a low-pressure appliance connector. Common applications include:
The 3/8" female NPT end threads onto a standard 3/8" male NPT propane fitting -- found on many regulator inlets, high-pressure manifold outlets, and appliance inlets. The 3/8" female flare swivel end mates with a standard 3/8" male flare fitting, common on POL-to-flare adapters and tank pigtail outlets. If your tank has a POL valve, you will need a POL-to-3/8" male flare adapter (sold separately) -- this hose does not include one.
