The hose has a female ball fitting on one end. It is advertised as a 1/4" female NPT ball. If you try to install an Acme propane fitting or quarter inch NPT pipe it will leak. To fix this and ensure no leaks If you have one, you'll need to order a 1/4" ball-to-NPT adapter. Raven carries it. Unfortunately, the ball fitting on the hose probably uses NPS threads and an NPT ball adapter will do, but it's very tight.
