The awesomeness of the 60 duro LX o-ring, long spring at 235 fps...

[sniper1rfa]

So i's a little mixed up and (***)backwards. It happens. I was talking about the 6th dimension's... uh... dimension. yeah.

I just grabbed some rings from a kit we had at school, didnt pay much attention. they work good, okay?

Wouldn't a softer oring have more grab?

It's like throwing one of those gooey wall crawlers on your wall and watching it stick, versus a g-i joe. Obviously the wall crawler will have more resistance against the wall because it adheres to it easier.

But maybe that's just me.

"Wouldn't a softer oring have more grab?"

I thought the same thing. A softer o-ring seems like it would have more friction, thus a faster breakdown.

o-rings seal by deforming or squeezing against the object
being sealed. a softer o-ring will deform more easily to
achieve the same level of seal.

also nitrile (buna-N) has a lower co-efficient of friction
than urethane.

Finally all o-rings have mold flash on the inside and outside diameters,
so when you put that new urethane o-ring
in, after a while the inside flash will wear off and maybe
allow a leak

[sniper1rfa]

probably not, o-rings tend to have a certain amount of pop, where the pressure deforms them to get a seal. Thats why the same o-ring worked in bot a 0 and a .5 carrier.

Coefficient of friction is a totally different thing from hardness or elasticity.

yes of course they are.
