Use this propane ACME nut to connect a 20lb or 30lb propane tank directly to your regulator without a pigtail. It allows a simple hand-tighten connection and is a great alternative to the traditional POL which threads inside the valve.This product has vital RV industry safety features, including excess flow and thermal shut-off protection. Nut is rated to 200,000 BTU/hr.
1/4" male NPT x ACME thread.
Please note that you should not use the black version of this device with RV regulators. The black nuts are designed to work with BBQ grills and have a much lower shut off limit. Black nuts typically shut off at 70,000 BTU/hr or even lower, too low for most RV systems.
