Riley ★★★★★

I replaced some old Buna-N seals with these Viton O-rings and immediately noticed they handle the higher heat near the engine bay much better. The 0.139" cross-section fits the groove perfectly, and the 75 durometer feels just right for a snug, leak-free seal.

Michael G. ★★★★★

The brown colour makes them easy to spot among my spare parts, and the 75 durometer hardness is just right for the moderate pressure fuel line I'm using them on.

Joshua P. ★★★★★

I needed a seal that could handle high heat in my compressor setup, and these Viton FKM o-rings are rated up to 400°F. The 0.859" inner diameter was a perfect fit for the port, and the brown color makes them easy to spot during installation.
