H5.7X234.3 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 234.3 mm (9.224 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 245.7 mm (9.67 in). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware. This item is further identified as Metric O-RING, JIS G235.

Buna-N (Nitrile) is known for strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. This material stands up to greases and lubricants, water, and propane and butane. 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 automotive brake fluid are present.

It sees regular use in automotive, hydraulic and pneumatic systems, and construction equipment.

H5.7X234.3 ships individually. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
