The H3.5X66 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 66 mm (2.598 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 73 mm (2.87 in). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against greases and lubricants, petroleum-based oils, and hydraulic fluids. Buna-N (Nitrile) delivers the most widely specified general-purpose sealing elastomer and low compression set under sustained load. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C).

Typical settings include agricultural equipment, automotive, and construction equipment.

H3.5X66 ships individually. Unit weight is approximately 2.566 g. 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.
