DIY: Oil Pressure Gauge

Chiefish

Spearfish,
teflon tape has no business on straight threads, (BSP). I've seen it where people have put it on drain plugs, and it has gotten into the oil system. it is possible for some of the tape to make it into the fittings, and gum them up, rendering the readings innacurate.

It's not that it had no business....because that's not true. When used correctly it's completely fine. Trick is to not put too much on and to ensure you don't let any roll over the edge of the fitting so that it would be in the oil stream. I use it sparingly and keep it neat and it's no issue. Also important to clean up any left on threads when taking parts apart that have it.

I agree with Mozen. The trick is to have the tape only on the threads and not at the end of the fitting. I've been doing this for as many years as I can remember having teflon tape. A sloppy taping job could cause problems.

Yes and no

If its straight threaded, it should come with a grommet to ensure the seal, if not a smear of red rtv at the base... teflon can get ugly if a piece spits up into the pressure sender or get to travel around the system. if a fine strip is added at the base of the adapter thread, that should never happen, but if it covers all threads, theres a good chance of chewed up teflon floating aorund in in the system
