A direct, no-adapter connection between a standard Type 1/QCC1 propane cylinder and any regulator with a 1/4-inch inverted flare inlet. Built with a braided stainless jacket and rated for outdoor RV, trailer, and portable appliance service.
The Flame King E15INPT is a 15-inch propane supply hose designed to connect a QCC1 (Type 1) propane cylinder -- the standard tank used on most travel trailers, 5th wheels, and portable grills -- to a regulator or manifold with a 1/4-inch inverted flare (POL-style) inlet. The ACME left-hand threaded nut on the tank end tightens quickly by hand; no wrench needed on that side. The inverted flare fitting on the regulator end threads in with a standard wrench.
At 15 inches, this hose is the most common pigtail length for dual-cylinder manifold setups, where two tanks are plumbed to an automatic changeover regulator mounted between them on the tongue. It also works as a single-tank supply line wherever the tank sits close to the regulator.
ACME left-hand threaded nut fits all standard 20 lb, 30 lb, and larger DOT cylinders with a Type 1 valve outlet.
Male 1/4-inch inverted flare fitting connects directly to compatible regulators and manifold inlets -- no adapters required.
Outer braid resists abrasion, UV, and road debris. Suitable for permanent mounting on trailer tongues and outdoor cabinet installations.
Tested and listed to CSA standards for LP gas hose connectors used in recreational vehicle and outdoor applications.
This pigtail is the standard supply line used in these RV and outdoor setups:
The tank end (ACME/QCC1) fits all standard Type 1 cylinder valves -- the same connection used on most 20 lb barbecue tanks and RV propane cylinders sold in North America. The regulator end (1/4-inch inverted flare) fits regulators and manifolds that accept a male inverted flare, including most Marshall Excelsior, Cavagna, and Rego-style RV changeover regulators. If your regulator has a POL (left-hand external thread) inlet instead, this hose does not fit directly -- you would need a POL-to-inverted-flare adapter or a different pigtail.
QCC1 (Type 1) is the modern standard. The fitting has a large plastic or brass ACME nut that threads onto the outside of the cylinder valve. POL is the older standard -- a brass plug with left-hand external threads that screws into the cylinder valve. Most cylinders manufactured after 1998 use QCC1. If your tank has a recessed valve with a handwheel, it is almost certainly QCC1 and this hose is the correct fit.
Propane hoses should be inspected before each season and replaced every 5-10 years regardless of visible condition. Check for cracks in the hose body, corrosion at the fittings, and any signs of kinking. A hose that has been pinched, driven over, or exposed to extended direct flame contact should be replaced immediately -- do not attempt to repair a propane hose.
