Oil gauge should be sealed?

    I would like to change electric switch oil pressure for oil gauge (this close to rear cylinder on the right side). So I will mount switch fitting and oil gauge. The question is should I seal threads in fitting and oil gauge or not. If yes, how to do it. Should I use just a silicone or plumbers tape.

    No sealant necessary . They are a pipe thread which is tapered.

    Piotra you don't have to give up your electric (light) on the oil pressure gauge changeover. JP Cycles offers a dual adaptor so you can have both. JP part #740-581. PS-Glider I know that the sealent isn't necessary but I used a teflon paste because I'm just cautious. This set up has never leaked.

    See, You'll get Many opinions here.. I (I) like to use teflon tape.. Never have bought any paste.

    Not saying Right or Wrong here at all.. Just what I use.

    Teflon gets a "bad wrap" some times because of the user not the use.

    I Carefully apply the tape on Some fittings like this one. I think it makes it easier on the parts together and when back apart..

    Neatly done and applied on a few fittings like the pressure one IMO I don't have to torque the metal to metal as tight.. Not wearing the pipe threads.

    Like the older style chaincase magnetic plug, the 1/8 pipe thread that usually leaks after a time because of In and Out sooooo many times..Then finally is inside the drain hole too far. and not sealing off.

    1/8 taper in 1/2 to 3/4 inch is Very little. I have had a plug last me for years Only because I used Teflon Tape..

    Just My Way

    Just my Way bubbie...I like it...yeah also would use sealer so less "need" to tighten that tapered plug too tight, it is easy to "muscle" it...not that any of us would do that! :s
