The 2.5mm cross section provides excellent extrusion resistance and durability compared to standard thinner O-rings, making them ideal for high-pressure applications and industrial environments where reliability is critical. This thickness offers a good balance between sealing performance and installation ease.

Yes, NBR (Nitrile Rubber) offers excellent resistance to oils, fuels, and hydraulic fluids, making these O-rings perfect for automotive, industrial, and machinery applications where oil exposure is common. NBR maintains its sealing properties even when exposed to petroleum-based products.

These NBR O-rings perform reliably in temperatures from -40°C to +120°C, suitable for most industrial applications including outdoor equipment and machinery operating in varying climate conditions. For continuous high-temperature applications above 100°C, consider our specialized high-temperature compounds.

These heavy-duty O-rings are ideal for hydraulic systems, pneumatic equipment, automotive applications, industrial machinery, pumps, compressors, and any application requiring reliable sealing against oils and petroleum-based fluids. The 2.5mm cross section makes them particularly suitable for medium to high-pressure applications.

Measure the groove diameter where the O-ring will sit. Our O-rings are specified by outer diameter (16mm-250mm) with consistent 2.5mm cross section. For dynamic applications, ensure proper compression and clearance for optimal performance. Contact us if you need assistance with sizing for specific applications.

These O-rings have a 70A Shore Durometer hardness, which provides an excellent balance between sealing capability and mechanical strength. This hardness level offers good compression set resistance while maintaining flexibility for effective sealing in both static and dynamic applications.
