Anyone know of a source for Chinese hydrualic fittings. I tried to hook up my backhoe and found that the wrong fitting was put on the pressure side. It is too small for the o ring flanges that go on each side of the pump. Local hydraulic shops say this is a fitting which is expressly banned by some international hydraulic standards ... I'm being sent a whole new hose from the factory, but I'm worried about having to do this each time I have a problem with a hose.
