Customer Reviews (4.4 / 5 · 5 reviews)

Hazel Z. ★★★★★

The metal-detectable feature saved me during a recent FDA audit, these rings hold a tight seal at 200°F without any issues. They feel a bit stiff at first but seat perfectly once installed, and the 40-pack is great value for the price.

Ava ★★★★★

I was skeptical about the 70 durometer hardness, but these o-rings seal perfectly in my hydraulic fittings without being too stiff to compress. They handle the temperature swings in our manufacturing area without any issues.

Scarlett E. ★★★★★

The metal-detectable feature gave me peace of mind on our food processing line, and the -40°F rating is perfect for our cold storage room. These 70-durometer rings seated nicely without any distortion, and forty in a pack is plenty for a full rebuild.
