Question by: Kirk T on Oct 18, 2025, 7:23 PM

For a -10 MORB or SAE port that uses an O-ring, this matches that size callout. It is the Brennan 4000 series O-ring with a 0.755 mm inner diameter spec and it is listed for 5/8 inch tube OD.

What's this o-ring made of, and is it gonna hold up around hydraulic oil?

Question by: Marvin S on Jun 28, 2025, 9:28 AM

NBR, which stands for Nitrile Butadiene Rubber, is exactly the material you want when hydraulic fluid is in the picture. It handles oils well and keeps its shape under pressure, so leaks stay out of the equation. The 90 durometer hardness rating means it's on the firmer side, which works in its favor for demanding industrial setups.
