A properly rated LP pigtail is not a place to cut corners. The MER425-60 gives you a UL-listed, CGA-approved 60-inch connection between your RV propane tank and regulator -- with fully crimped brass ferrules, built-in thermal protection, and a 200,000 BTU/hr flow capacity that keeps up with high-demand appliance loads.
Marshall Excelsior has manufactured LP gas equipment in the USA for decades. The MER425-60 pigtail hose is built to their exacting standards for RV and recreational vehicle propane service -- connecting a standard QCC Type 1 (Acme) tank valve to a 1/4" male inverted flare inlet on a two-stage or single-stage regulator.
At 60 inches (5 feet) of usable length, this pigtail gives you enough reach to connect dual-tank setups through a changeover valve or to route the hose away from heat sources and sharp edges. The flexible thermoplastic construction resists kinking and holds its shape across a wide temperature range.
Rated for 350 PSIG working pressure -- well above the 250 PSIG typical of a full propane cylinder -- giving a solid safety margin in RV service.
High-flow QCC connector delivers up to 200,000 BTU/hr and 100 SCFH, enough to feed multiple RV appliances simultaneously without starving the regulator.
Integral thermal protection shuts off gas flow automatically if the hose is exposed to excessive heat -- an important safety feature for enclosed propane compartments.
Both ends are factory-crimped with brass ferrules -- no clamps to loosen over time, no DIY assembly required. Leak-free connections right out of the box.
The female QCC Type 1 end (also called an Acme nut or POL-replacement connector) threads onto any standard 1-5/16"-18 ACME male outlet found on US propane cylinders of 4 lbs and larger -- including the common 20 lb and 30 lb tanks used in most RV dual-tank setups. No tools required to connect; hand-tighten the swivel nut and the internal check valve in the tank valve opens automatically.
The 1/4" male inverted flare end connects directly to a regulator, changeover valve, or T-fitting inlet that accepts a standard 1/4" inverted flare (SAE 45-degree) fitting. This is the most common inlet thread on two-stage RV regulators. Tighten with a wrench -- do not over-torque brass fittings.
The hose body is a flexible thermoplastic construction approved by both UL (Underwriters Laboratories) and CGA (Compressed Gas Association) for LP gas service. The 1/4" nominal hose ID supports the rated flow without excessive pressure drop. Both end fittings are brass, factory-crimped with no reusable or field-replaceable ferrules.
Manufactured in the USA by Marshall Excelsior Company, a Michigan-based LP gas equipment manufacturer with a long track record in the RV, agricultural, and industrial propane markets.
