If you're referring to the size of the fittings at the first stage end of the hoses, they both should be 3/8" male threads. That's pretty standard in the industry. The HP hose thread will be 7/16". Occasionally you'll find an older first stafe with an HP port that's 3/8" and you must be careful not to put a LP hose in there.
