Benjamin S. ★★★★★

I needed a batch of reliable 137-size o-rings and these fit perfectly into my air line couplers, with the 50 durometer giving just enough flexibility. The package of 200 is great value for the price compared to buying them individually.

Madison A. ★★★★★

The 2.049" inner diameter is spot-on for my pump repair, fitting snugly without any deformation. These 50 durometer rings have held up perfectly under constant water exposure so far. I'm impressed with the consistent quality across the entire 200-pack.

Emily F. ★★★★★

Fitting these o-rings on a hydraulic cylinder was a breeze; the 50 durometer is noticeably softer than the standard 70, which made installation much easier. The 200-count pack means I have plenty of spares for future maintenance.
