Finally found a 90-durometer FKM that actually seals my high-temp hydraulic line without leaking after a few cycles. The 0.139" cross-section fits snugly into the groove, and the package of 125 should last me years.

I’ve been using these o-rings on a pneumatic actuator that cycles between -10°F and 200°F, and they’ve held their seal perfectly. The 90 durometer feels noticeably stiffer than standard Buna-N, which is exactly what I needed for the higher pressure rating. They came well-packed and fit the groove wi

I work on a hot oil system that hits 350°F regularly, and these Viton o-rings hold their seal perfectly where nitrile would have failed in weeks. The 90 durometer is firm enough to resist extrusion, and they slide into the groove without cracking.
