Sophia N. ★★★★★

The -15°F to +400°F temp range gives me peace of mind for my outdoor hydraulic equipment, and the 75 durometer feels just right. Fit perfectly on my pump port, and the brown color makes them easy to spot during maintenance.

Sophia V. ★★★★★

I needed o-rings that could handle high heat, and these Viton FKM ones are rated up to 400°F, which is exactly what my application required. The 75 durometer feels firm and durable, and the 10-pack gave me plenty of spares.

Lily ★★★★★

These fit perfectly on my old hydraulic cylinder that I rebuilt last weekend. The 4.475" ID was exactly what I needed, and the brown Viton material feels high quality.
