Hope someone can help with what should be something very simple. I cannot get an adaptor to fit R410A hoses to my jvac pump. Pump has 3 connections with caps. One 1/2 acme one 1/4 and one what I think is 3/8 or 5/16th ?
I bought a 5/16 to 1/4 adaptor which fits the 5/16th (or 3/8) but unfortunately gives me 1/4 male again so no better off. I seem to need female 1/4 to male 5/16th. Hoses are correct as they fit service valve on a R410a split. Help appreciated
