Julian B. ★★★★★

Had to replace a few old seals in a hydraulic line, and these AS568-218 o-rings fit perfectly with that 1.234" inner diameter. The metal-detectable feature is a nice bonus for our shop's safety checks.

John G. ★★★★★

Installed these in a food-grade pneumatic line and the metal-detectable property is a huge relief for our QC checks; they seated perfectly in the gland without any distortion. The 70 durometer feels firm enough for sealing at 200°F, which is right in our operating range, and the bag count was exact.

Steven ★★★★★

The metal-detectable feature gives me real peace of mind in our food processing line, and these 70 durometer rings fit perfectly on our pneumatic fittings. They're a solid upgrade from standard black o-rings for safety compliance.
