Steven K. ★★★★★

Finally found some 4.475" o-rings that actually seal my tractor's coolant lines without leaking. The 300°F rating gives me peace of mind even under the hood.

Grace P. ★★★★★

The 70 durometer is exactly what I needed for a seal that has to hold up in an outdoor hydraulic system. These EPDM o-rings feel consistent and durable, and the temperature range covers my application perfectly.

Henry ★★★★★

The 4.475" inner diameter fit my application perfectly, and the 70 durometer feels like the right balance of firmness and flexibility. I've used them in a hot water setup around 180°F so far with no signs of swelling or hardening. Exactly what I needed for a bulk pack.
