Sebastian F. ★★★★★

The 50 durometer is noticeably more forgiving than standard 70s, which was perfect for sealing a slightly worn flange without over-compressing the o-ring. Cured a persistent leak on my hydraulic cylinder that stiffer rings couldn't handle. Glad this size was available in a 55-count pack.

Joseph T. ★★★★★

I needed these for a pump rebuild and the 1.725" inner diameter fit perfectly on the shaft. The 50 durometer rubber seals well without being too stiff to compress by hand.

Charlotte ★★★★★

The 50 durometer on these was just what I needed for a light seal application—they compress nicely without being too stiff. Arrived quickly and the bag of 55 will last me through several projects. Exactly the AS568-327 size I was after.
