I found the quick disconnect coupler fitting on my compression tester hose fits the air hose couplers too. All you have to do is remove the Schrader valve on the other end of the hose to allow air to flow thru it, so you can supply air into the cyldr.The home made tool. The one I have apart is the small thread and the last is the large thread plug B4 modified. The porcelain part is the same size on both plugs.
