Q:I need a new fuel shut off valve for a sediment bowl on an Allis Chalmers B. Was looking for a quick fix instead of needing to buy a whole new unit. Anyone know if this would work? Picture has the new sediment bowl from Steiner.

      A:  It is put there to keep the air from leaking out at that point. You could put on some Teflon tape to solve your issue.

        A:  It fit perfectly. Only took 5 minutes to replace my old one. Works great.

        by|Feb 9, 2022

        A:  The red stuff is thread sealant which is pre-applied on some accessory fittings. If the valve does not have any thread sealant, simply wrap the threads (approximately 4-5 wraps) with Teflon tape prior to installing the drain valve.

          A:  Threadlocker. It keeps screws from vibrating out.

              Installed the Powermate 1/4in. drain valve on my air compressor. The old drain valve was not sealing properly. This one installed easily and is holding the pressure, even when just tightened by hand. That's the goal, no wrenches or pliers used on this drain valve.

              Easy to use!
              I replaced my drain on my air compressor. It wasn’t working properly so I purchased these and they are much better. Easier to turn to drain. My old one required a pair of pliers to turn it to drain, then it finally broke.
