The RV Thermo Pigtail (Type I ACME) provides a safe, user-friendly connection from your Marshall Excelsior MEGR-253/253H regulator to a standard LP gas cylinder without the use of a wrench. The easy to tighten nylon nut swivels on a connector fitting that is heat sensitive. Inside the brass nipple is a flow-limiting device designed to sense excess gas flow. If excessive gas flow is detected, the RV Thermo Pigtail will shut down the flow to a maximum of 10 SCFH (by-pass flow).|Note: MEC Green type I nut for use on RV application only (200,000 BTU per hour)|Between 240 degree F and 300 degree F the brass nipple displaces (approximately 1/4 in.) closing the cylinder valve module and stopping the flow of gas from the container|20 in.
