Go with the Extend-a-stay.. They can provide a fitting that matches the inlet hose of the Extend-a-stay adapter, and you simply hook up and unhook from that fitting,, Just what that fitting is TODAY. I don't know, Mine (An older model) is a Prest-O-Lite (POL) fitting,
The Extend-a-stay is designed for use on short tanks (Say 20-50 pound) but with a high pressure line ending in the proper fitting will work with any tank.
Home is where I park it!
