Retaining Ring, M38 Internal

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.

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.

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.
