Sofia ★★★★★

Finally had to swap out the old seals on a pump flange at work, and these fit perfectly right out of the bag. The 90 durometer feels noticeably stiffer than the 70s I’ve used, so I trust them to hold up in the heat range they promise. Pack of 100 means I’m set for the next several rebuilds.

Ava ★★★★★

I needed a pack of 337s for a hydraulic repair and these fit perfectly — the 90 durometer gave me the firm seal I was after. The 2.975" inner diameter matched my groove dimensions exactly, no guessing. Glad I grabbed the 100-pack, plenty to spare for future jobs.

Thomas A. ★★★★★

I was worried about getting a consistent seal on my hydraulic fittings, but these 337s measure exactly to spec and the 90 durometer feels plenty stiff for high-pressure lines. Installed a full set this weekend and they seated perfectly without any twisting.
