Here is a source for Viton o-rings:
mcmaster.com

If I had known about this source on Viton a year or so ago I would have used it instead of the New Old Stock "O' rings that the dealers are passing off on us. I have been putting it off...but I will use Viton when I change them out on the IP delivery lines. They are not that expensive.... the only draw back is that they are in packs of 25 or more. But at $4.50 to $8.00 dollars a pack
depending on size... whats the difference if you have a few left over. Besides you can send them off by mail to another member in need!
Any idea what the size (ID & OD) is of the ones used on the delivery lines?
Cheers,
