I just wanna make sure this oring fits my metric port. How do I know if it's the right size?

This oring is identified by the supplier part number OR-42MM, which should help you confirm compatibility with your equipment.

what exactly is this o-ring for, like what kind of port does it fit?

Question by: Dustin H on Jan 4, 2026, 4:39 PM

Metric port o-rings like this one are used to seal threaded hydraulic fittings at the port connection point. The OR-42MM from Adaptall is sized for a 42mm metric port, so it sits in the groove at the face of the fitting or port boss and creates a leak-free seal when the fitting is tightened down. Pretty standard setup in hydraulic systems that use metric porting rather than SAE or NPT.

got an OR-42MM in my hand. is this just a sealing o-ring for a metric port on a hydraulic setup?

Question by: Bobby S on May 20, 2025, 4:58 PM

Used as a metric port O-ring, it’s meant to provide a seal in hydraulic applications. This one is the Adaptall part OR-42MM, and it’s called out specifically as a metric port O-ring used for reliable sealing.
