I've been very happy with the o ring routine. It corrects for fititings that

either have hardened or got misshapen by misapplied force, or rounded nuts.

Also, if the fitting is in decent condition, the fitting is leakproof and

secure with very low force, thus preserving the nuts. Unfortunately, there's

no way of knowing ?which? Teflon is in which o-rings, but the ones I have

have worked since MTBE has been used in our California Rotgut gas.

I've given up on teflon for the pipe threaded connections. MTBE gas just

seems to seep through anyway. And the shredding is no help. I resorted to

good ole Permatex.
