Crush washers..

Acctualy I need two adam, and seriously I’d rahter just get a couple from you if I could rather than go buy an assortment of ones I don’t need…

Any chance you have 1/8th adapter fittings as well for an aftermarket oil pressure gauge…

As no one at any parts store around here grasps the concept of a female->male adapter fitting

The aftermarket uses a 1/8th something or other fitting versus the 1/8th NPT stock fitting
