A while back on AR15.com someone posted that they found a Viton O Ring from McmasterCarr that was basically the samething as the Crane O ring. Anyways, I subscribed to the thread but it is over 30 days old and I can't see it. Does anyone happen to know what the Mcmaster Carr part number is?

I've always been confused by that advice... "Get a #60 o-ring"

O-rings are given dash numbers that correspond to physical size. those dash numbers start at 1 and stop at 50 (55 for the high end stuff), then re-starts at 102 and continues through 475.

I have yet to find a "#60 o-ring" :confused:

Yes, thank you!

Just take the extractor with spring to the local hardware store and ask to see the O-rings.

Wouldn't the oil and solvents break down the regular rubber ones? That is reason the Cranes and the MC ones are viton right? I know viton stands up to oils and other petroleum based products.

I know it worked on my Bushmasters. But I dont have either of them any more so I cant say for sure if they hold up long term.
