Customer Reviews (4.6 / 5 · 5 reviews)

Victoria ★★★★★

The temperature range on these is perfect for my outdoor pneumatic system; they handle the harsh winter cold without cracking. The 5.734" inner diameter fit my cylinder cap exactly as needed. Exactly what I was looking for to seal a stubborn air line connection.

Mia L. ★★★★★

Got these for a hydraulic rebuild and the 70 durometer EPDM is exactly what the spec called for. Fit the gland perfectly, no trimming needed. Arrived well-packed with all 100 accounted for.

Charlotte ★★★★★

Finally tracked down a proper AS568-256 for a stubborn hydraulic cap, and the 0.139" cross-section seated perfectly. Held up to 300°F during a steam test without any distortion. Will be ordering another pack soon.
