Ryan Q. ★★★★★

The groove fit was spot on for my housing bore, and the internal release action seated it firmly without any prying or fuss. Exactly the M38 size I needed, and it held up through a couple of installs without bending.

Miles G. ★★★★★

Picked up an M38 internal ring for a small hydraulic cylinder rebuild, and it snapped right into the bore groove with a solid click. The internal retaining design is exactly what I needed to hold the assembly together without extra hardware.

Grace X. ★★★★★

Used this internal ring for a bore repair on a piece of machinery and it snapped into the groove perfectly. The M38 sizing was spot on, no filing or adjustment needed to get it seated right.
