Violet G. ★★★★★

I needed Viton o-rings that could handle the heat near my grill, and these 70 durometer ones seal perfectly at 400°F without any swelling. The 4.734" inner diameter was a spot-on fit for the groove I measured.

Emma J. ★★★★★

Finally found the right size for a high-temp hydraulic repair I've been putting off. These 4.734" ID rings slid on perfectly, and the Viton material feels noticeably more durable than the standard rubber ones I used before.

Eva ★★★★★

I was pleasantly surprised by how much heat these o-rings can take, rated up to 400°F. The 4.734-inch inner diameter fit perfectly in my pump rebuild kit.
