O Ring

[zReaperAssassin]

So, I was wondering what the best o rings for an AEG Piston head were. The stock ones aren’t very ideal, and trying some ones from Amazon, but my FPS went down by 35 in a few weeks so guessing they aren’t working very well (was a 15/16” OD x 3/4” ID x 3/32” width). Was looking at black blitz X Ring. Are they very good, otherwise what else?

Thanks!

Well for starters, they're metric Orings.
Second, Buna nitrile or viton is often the best material.
Unless your stock Oring is worn out or the wrong size, the issue is the grease, not the Oring material.

I ordered the blackblitz x-rings after I realized that my o-rings were toast. Worked great for me, seals tightly.

Ah, didn't know they were metric. Was just going off of a teching document for various o rings and different forums. (Here's a link to the current orings I am using, guessing they are just silicone https://www.amazon.ca/gp/product/B00...?ie=UTF8&psc=1)

I am currently just using some standard grease, think it is teflon grease I am using, but just a no name brand. What would you recommend for compression parts?
