Benjamin E. ★★★★★

I needed a bunch of these for a pneumatic rebuild, and the 70 durometer is just right—soft enough to seal but still firm. The inner diameter fit my groove perfectly on the first try.

Ryan H. ★★★★★

These rings seated perfectly in the hydraulic fittings I use for an assembly line jig. The 70 durometer feels just right—firm enough to hold pressure but not too stiff to install by hand. I've already used a handful and they're holding up great so far.

Christopher ★★★★★

I needed a bulk supply for a pneumatic system rebuild, and these 137-series o-rings have the exact 2.049" ID I was looking for. The 70 durometer material seats well without being too stiff, and the pricing for 500 pieces saved me over buying individually.
