Description

The Marshall Excelsior MER425-18P is an RV thermo pigtail designed to provide a safe connection from a regulator to an LP gas cylinder. It features a female QCC, Type 1 connection and a 1/4" male inverted flare fitting. The 18-inch hose includes a flow-limiting device inside the brass nipple, which will shut down gas flow to a maximum of 10 SCFH if excess gas flow is detected.
