Customer Reviews (4.6 / 5 · 5 reviews)

Chloe W. ★★★★★

The bright red color makes these easy to spot in my parts bin, and the 70 durometer silicone is flexible enough to get a reliable seal without needing excessive force. I've had them installed in a low-pressure water line for three weeks and not a single drip.

Grace ★★★★★

Finally found a seal that stands up to hot oil without swelling at all. The red color makes them easy to spot against dark machinery.

Joshua ★★★★★

We needed o-rings that could handle high heat for a commercial kitchen repair, and these silicone ones with a 450°F rating fit perfectly. The 4.234" inner diameter was spot on for our application, and the red color made them easy to see during installation. A solid purchase for the price.
