H7X335 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 335 mm (13.189 in), a cross section of 7 mm (0.276 in), and an outside diameter of 349 mm (13.74 in). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
The compound resists many alcohols, water, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, strong abrasion and tear resistance. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Applications involving ketones or ozone and direct sunlight call for a different compound.
Typical settings include automotive, agricultural equipment, and fluid power.
Stocked as H7X335 and sold individually. Unit weight is approximately 51.075 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
