JR Products 07-31555 -- 20" OEM Propane Pigtail Hose, QCC1 to 1/4" Male Pipe Thread
A direct OEM replacement pigtail hose for RV LP systems. Connects a Type 1 (QCC1) propane cylinder valve to a regulator or manifold with a standard 1/4" male pipe thread. Thermoplastic construction rated for outdoor propane service.
The JR Products 07-31555 is a 20-inch OEM-style pigtail hose designed to link an LP cylinder to an RV propane regulator, dual-stage regulator, or manifold inlet. One end carries a QCC1 (Type 1) hand-tight connector that seats directly onto the outflow valve of a standard 20 lb or 30 lb propane cylinder -- no tools needed for the tank connection. The opposite end terminates in a 1/4" male pipe thread (MPT) fitting that screws into a regulator inlet, tee, or distribution line.
This is the hose that physically bridges the gap between your on-board LP cylinder and your rig's regulator assembly. When a pigtail cracks, kinks, or shows age-related deterioration, replacing it promptly with the correct OEM part is a straightforward safety measure. At 20 inches, this hose provides enough working length for single-cylinder setups where the tank sits directly adjacent to the regulator, and it is a common fitment on factory two-tank autoswitch configurations used on travel trailers, fifth wheels, and Class A coaches.
The Type 1 QCC1 fitting threads directly onto standard 20 lb and 30 lb propane cylinders. No wrench required at the tank end -- finger-tight seals the connection.
Standard 1/4" male pipe thread on the regulator end mates with most RV dual-stage regulators, autoswitch manifolds, and distribution line inlets.
Flexible thermoplastic construction handles outdoor temperature cycling and LP vapor without becoming brittle. Rated for propane (LPG) service.
Engineered to match factory pigtail dimensions used by many RV manufacturers. Part number 07-31555 cross-references to JR Products vendor part 13-3262.
This pigtail hose is the short connecting line between an LP cylinder valve and the inlet side of an RV propane regulator. It is commonly found in:
The QCC1 (Type 1) fitting used on this hose is the modern standard for consumer propane cylinders in North America. It replaced the older POL (left-hand thread) fitting. If your cylinders have a hand-wheel valve with a threaded outlet collar, they accept QCC1. If your tanks have an older exposed left-hand threaded stub, they require a POL hose instead. This hose is QCC1 only.
Propane pigtail hoses should be visually inspected before each camping season and replaced at the first sign of:
Apply approved leak-detection solution to all fittings after installation and before lighting any appliance.
