-152 WHITE BUNA 70D FDA O-RING

APG stocks the H70FDA152, an AS568-152 white Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 3.237 in (82.22 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.443 in (87.45 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists water, greases and lubricants, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is known for reliable performance in both static and dynamic service, low compression set under sustained load. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or ozone and direct sunlight will shorten service life.

This o-ring meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include agricultural equipment, automotive, and construction equipment.

Reference part number H70FDA152 when ordering; the item is sold individually. Nominal inside diameter is listed as 3 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
