O-Ring material

That is the reason for this post. To get educated on which will serve me better, Buna-N or Viton. Buying bulk will be less expensive than buying one or two at a time at the dealer. Compared to buying one at a time, Viton in bulk is still a bargain. Even at 3-4 times the price of Buna-N. But if there is no need for Viton over Buna-N that's what I'll buy.

Excellent. Rather than buying in bulk, just mail order or go to your local hydraulic shop and buy the kits you need. Probably a lot less expensive than you ever thought.

Viton or Buna-N? Which is better for hydraulics? Viton costs more, is it worth it? Planning on stocking up on ORFS and ORB O-Rings.

Buna-N, 90-durometer definetly for ORFS & ORB......:thumbsup:

If it's used in a static seal (staionary ) use 90 duro

if it's used in a dynamic seal (moving) use 70 duro

Viton not important as the only advantage would be in a high-temp environment or odd chemical resistance....

Also buying in bulk is not a great idea cuz orings have a definet shelf-life (5 years or so)

Oring kits are the best option for everyday usage....then refill from your local supplier that has fresh ones on-hand....

I have a drawer full of new o-rings about 15-20 years old I think and they are mostly worthless.
