: I replaced 2 lead threaded cap seals/gaskets on an old Thrush water pressure regulator. They don't drip water, but they are wet and show a little water. The new gaskets are fiber since supply was limited on a Sunday. Should I get different ones, or will it stop seeping/weeping?
The fact that the fiber gaskets are still wet indicates that the TENSION held against them by the mating surfaces is not great enough to prevent weeping through the threads. If the weeping persists for more than 24 hours, it will continue. It you remove the seals again, look closely at the mating surfaces. Oftentimes they are scored and even good gasket material can't close the gap perfectly. a lille file sometimes helps. A rubber gasket has more expansion requiring less tension. Lead is NOT RECOMMENDED in areas exposed to children.
