The MB Sturgis 06-1369 is a 12-foot thermoplastic propane pigtail hose designed to connect individual LP cylinders to a dual-cylinder two-stage regulator system. The POL (Prest-O-Lite) tank connection delivers higher flow capacity than a standard Type 1 (QCC1) fitting -- a critical advantage when high-demand RV appliances cause bypass or starvation issues on a busy system.
When your RV is running a furnace, water heater, refrigerator, and cooktop simultaneously, a standard Type 1 QCC connector can become the bottleneck. The POL fitting used on this hose opens the flow path wider, supporting up to 500,000 BTU per hour -- enough headroom for virtually any combination of RV appliances drawing from a typical 20 lb or 30 lb cylinder.
At 144 inches (12 feet), this pigtail gives you flexible routing from ground-level cylinders up to a wall-mounted regulator without kinking or straining the connection points. The thermoplastic hose body is rated from -40F to 140F, handling everything from winter camping to summer desert heat.
Left-hand threaded POL (Prest-O-Lite) fitting with excess flow protection. Connects directly to standard LP cylinders with POL valves.
Engineered for high-demand RV setups. Supports simultaneous operation of multiple LP appliances without regulator bypass problems.
Maximum working pressure of 350 PSI -- well above typical LP service pressure -- for a substantial safety margin in residential and RV propane use.
Rated -40F to 140F (-40C to 60C). Flexible and reliable in cold-weather camping conditions where standard hoses can stiffen and crack.
Type 1 (QCC1) fittings are the most common on modern RV propane systems and include an internal excess flow check valve. However, that check valve restricts maximum flow. On high-demand systems -- especially dual-appliance or large-capacity setups -- that restriction can cause the regulator to "bypass," where the second-stage regulator mistakenly detects excess flow and reduces output pressure.
Switching to a POL connection eliminates the Type 1 flow restriction. The POL fitting on this hose still includes an excess flow device to help limit flow during hose failure, but it is designed to pass the higher volume needed for demanding RV applications.
The hose body is 1/4-inch ID thermoplastic -- flexible, kink-resistant, and compatible with LP gas (propane). The outlet end terminates in a 1/4-inch Male Inverted Flare fitting, which mates with the standard inlet port found on most two-stage RV propane regulators.
Install this pigtail between each LP cylinder valve and the inlet(s) of your two-stage or auto-changeover regulator. Hand-tighten the POL fitting onto the cylinder valve first, then use a wrench to snug (do not overtighten -- POL threads are brass and can be damaged). Leak-test every connection with approved LP gas leak detector solution before lighting any appliance.
