-114 WHITE BUNA 70D FDA O-RING

APG stocks the H70FDA114, an AS568-114 white Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 0.612 in (15.54 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.818 in (20.78 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists propane and butane, hydraulic fluids, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for low compression set under sustained load, reliable performance in both static and dynamic service. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving strong acids or automotive brake fluid call for a different compound.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. Maintenance and OEM teams specify it across hydraulic and pneumatic systems, automotive, and fluid power.

This item is sold individually under part number H70FDA114. Unit weight is approximately 0.378 g and nominal inside diameter is listed as 5/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
