Product Specification

-
H6X429 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 429 mm (16.89 in), a cross section of 6 mm (0.236 in), and an outside diameter of 441 mm (17.36 in). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, Buna-N (Nitrile) is valued for an economical choice for high-volume maintenance programs and low compression set under sustained load. Expect good resistance to hydraulic fluids, propane and butane, and petroleum-based oils. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Applications involving ozone and direct sunlight or strong acids call for a different compound.

Maintenance and OEM teams specify it across automotive, agricultural equipment, and construction equipment.

Reference part number H6X429 when ordering; the item is sold individually. Unit weight is approximately 47.231 g. Check the compound against your process media, pressure and temperature before committing to a design.
