Customer Reviews (4.4 / 5 · 5 reviews)

Michael ★★★★★

The 3.35-inch inner diameter fits perfectly on my hydraulic fitting, and the 75 durometer feels firm yet pliable during installation. Already ordered a spare pack.

Ryan M. ★★★★★

I've been using these Viton O-rings in my high-temp coolant system, and they've held up perfectly at 400°F without any swelling or cracking. The 75 durometer hardness feels just right for a snug seal.

David K. ★★★★☆

The high-temperature rating is what I needed for a compressor seal, and these have held up perfectly so far. Only minor thing is the packaging could be sturdier, but the o-rings themselves are solid.
