Doesn't the fitting on the gauge use a barrel compression fitting.I am debating using silicone on my mechanical oil pressure guage inside my car is that bad? I don't know if I would trust Teflon tape on the inside of the car, the interior will be nice and I sure don't want oil dripping on the inside.
Thanks

Yep.. we use Hylomar all the time on the fighter enginesI'm sure that other stuff will work also however, I use Hylomar, (sparingly), to seal threads into oil or gasoline.
