Charlotte K. ★★★★★

I needed a seal for a coolant line that hits 200°F, and these -450s held up fine with no swelling or leaks. The 70 durometer felt pliable but sturdy during installation.

Ruby ★★★★★

These -450 o-rings fit perfectly on my air compressor check valve, and the 70 durometer feels just right for the pressure. I installed them in about 10 minutes and haven't had a single leak since.

Chloe F. ★★★★★

Finally got around to resealing my hydraulic press; these AS568-450 rings fit perfectly and the 70 durometer rubber feels nicely firm and durable. Held up great during the first test run at around 200°F.
