Product Specification

-
H2.4X5.3 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 5.3 mm (0.209 in), a cross section of 2.4 mm (0.094 in), and an outside diameter of 10.1 mm (0.4 in). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Buna-N (Nitrile) is specified here for strong abrasion and tear resistance, low compression set under sustained load. The material holds up against petroleum-based oils, propane and butane, and water. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where strong acids or polar solvents are present.

Common environments for this compound include fluid power, general industrial maintenance, and construction equipment.
