Ordered as H2.62X13.1, this is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 13.1 mm (0.516 in), a cross section of 2.62 mm (0.103 in), and an outside diameter of 18.34 mm (0.72 in). The o-ring compresses into its gland to block fluid or gas migration across a joint.
This material stands up to petroleum-based oils, many alcohols, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, low compression set under sustained load. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C).
Typical settings include fluid power, construction equipment, and general industrial maintenance.
H2.62X13.1 ships individually. Review your operating media and conditions against this specification before installation.
