    I have always used PTFE or stag.

    Stag is messy but smells lovely.

    Inverness means what method of sealing oil gauges for the temporary testing of oil pump pressure, as in the title of his thread.
    I just use ptfe tape on end of gauge and manifold and have to redo it every few times.
    I tried an O ring in the past, but gave up on that.
    Must admit there has to be a better, permanent seal to use, rather than tape

    Lol! I did read the post and then thought, - why are people advising using Hawk White or Stag on oil gauges? :p
    I often misread a lot of threads. A lot seem to have the question only in the title.

    I don't know why I miss read it tbh. Can you imagine using stag on your oil gauge? you would go home looking like a murderer!

    Did the O ring disintegrate mate? If so a different compound of rubber is required.
    Have a reference chart buried in a file somewhere of what compound can be used with which liquid but haven`t seen it in 20yrs!

    I use an aluminium washer. These can be taken off of scrap oil pumps.

    That's a good idea.
    One problem is often the oil gauge, or the manifold for it will tighten in wrong position - with gauge not facing where you could view it. That's why ptfe always does the job.

    I can't remember rpm why I stopped using an O ring, but certainly one problem was the final position the gauge tightened to
