O-RING GROOVE O005
The space into which an O-ring is inserted.
Dynamic O-ring grooves use a different dimension than static O-ring grooves. Most of the published reference material is for either static or reciprocating applications.
- Mechanical seals typically use a squeeze of less than 0.010″ (0.25 mm) on the dynamic O-ring if the surface finish on the sliding part is 32 rms or better.
- An O-ring can seal with as little as a 0.005″ (0.12 mm) squeeze.
