reuse crush type metal gasket?

chubba · Oct 4, 2015

Had a stripped thread on my fuel pressure regulator when installing new crush type gasket.

Helicoiled the thread, is there a reason I can't reuse this gasket, yes I know its been crushed but I can't think of a reason it won't still work?

Guess I'll find out a few miles on..

They crush to form a seal on uneven faces. Re-using a seal that has already been worked is not a good idea generally.

the surfaces are machined flat..my brain is finding it hard to understand why it won't work haha
guess there is a loss of pressure

its only clamped by 3 bolts

How flat is flat?
Machined surfaces will only seal together where they touch. Liquid under pressure finds very small gaps to go through hence gaskets that deform to touch both surfaces to effect the seal.
Slip guages that ring together may be flat enough (before deforming them under bolt loads) to seal but everything else needs a gasket of some sorts.

just replace it with a new one,not worth the trouble if it does not work.
