Q: Disecting a cut-off valve?
I have a fuel cut-off valve (two positions, either on or off) that is
seeping ever so slightly. That led to me taking it apart and examining its make-up, which leads to the following: 1. There is a thin copper washer or shim between the body of the valve and the top. It has in ID of about 3/4". Am I correct that it's purpose is to act as a gasket rather than a shim? I suspect that it's designed to be distorted to match the two mating surfaces and that means anytime the valve is taken apart, the copper gasket should be replace. Correct? 2. Valve stem packing: I can visualize leaks along the valve stem being controlled by either an 'O' ring or some form of packing. Is one better than the other ? Sorry, I don't recall what was orginally around the valve stem. If it was packing (vice the currently installed 'O' ring), is there a generic packing I can use or must it be specific to that valve? TIA - Mike |
