x-rings (or quad rings) are much better than a standard o-ring due to the dual sealing surfaces and the resistance to rolling on itself..
the next better choice would be a u-cup..
but the best choice is a polypak, which is just a u-cup preloaded with an oring..
the o-ring keeps the sealing lip of the polypak pressed tight up against wall of the cylinder, whereas, to some extent, the u-cup relies on pressure to create a seal..
and you can see that the polypak has a sealing surface that is square to the applied force, and an oring has a beveled edge exposed. so the oring has a better chance of being "pushed" back inside of the piston and letting fluid pass by..
polypaks also have a higher pressure handling capability than an oring..
not bad for a bag guy, huh?![]()
