Eli I. ★★★★★

I was a little worried about the fit, but the 4.484" inner diameter matched my equipment exactly. The red color makes them easy to spot during maintenance, and the -80°F to +450°F range covers every hot and cold line I've got.

Matthew ★★★★★

These o-rings fit my steam valve perfectly; the 70 durometer feels solid but still has enough give to seal. For the price of a 24-pack, it's nice to have spares without breaking the bank.

Samuel S. ★★★★★

I was a bit concerned about temperature range, but these o-rings have held up perfectly in my smoker griddle setup, handling 400°F without any cracking or hardening. The 70 durometer silicone feels durable yet pliable enough to create a tight seal on the first try.
