Richard U. ★★★★★

I've been using these o-rings for hydraulic system repairs, and the 90 durometer holds up perfectly under pressure. The temperature range is ideal for my shop where things can get pretty hot.

Stella ★★★★★

I use these for sealing fuel lines in a race car, and the 90-durometer material doesn't soften up under pressure like the cheaper ones did. The temp range down to -40°F gives me peace of mind for cold starts, and with 400 in a pack it's a solid value.

Victoria ★★★★★

These 90-durometer rings handled the heat cycle on my compressor without any softening, held their shape perfectly at 200°F. The 920 size was a snug fit on the first try, and having 400 on hand means I'm set for a long time. Exactly what I needed for a stubborn hydraulic line.
