Question by: Ricky T on May 26, 2025, 4:05 PM
What size is this O-ring exactly? I need to make sure it'll fit my metric application.
Answer by: Customer Support on May 28, 2025, 6:01 AM
This Hercules metric O-ring measures 19mm x 2.5mm, making it suitable for hydraulic systems, pneumatic equipment, and general industrial fluid power applications that require metric dimensions.
Question by: Norm G on Feb 22, 2026, 4:45 PM
Got some older European-built equipment that calls for metric o-rings at the cylinder end caps. Would a 19mm x 2.5mm fit what I'm describing?
Answer by: Customer Support on Feb 24, 2026, 7:00 AM
For cylinder end caps and port fittings on metric-spec machinery, that 19 by 2.5 sizing is exactly the kind of seal those systems are built around. European-designed equipment almost universally runs metric dimensioning, so if your spec sheet or service manual calls out 19mm inner diameter with a 2.5mm cross section, this is the right part. Worth cross-referencing against the alternate part numbers too, C1DF26, MI-02521693, and MINO-00407X93544, in case any of those show up in your equipment documentation.

got a metric groove that calls for 19mm x 2.5mm, is this the right o-ring size or am i missin something
Answer by: Customer Support on Apr 9, 2025, 6:17 AM
The key detail is the size. This one is a metric O-ring sized 19 mm x 2.5 mm, so it matches components that specify that exact metric dimension for the seal.
