1.5MM CS X 48MM ID BLACK BUNA 70D

APG stocks the H1.5X48, a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 48 mm (1.89 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 51 mm (2.01 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to many alcohols, propane and butane, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for low compression set under sustained load, strong abrasion and tear resistance. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C).

Maintenance and OEM teams specify it across general industrial maintenance, construction equipment, and agricultural equipment.

Reference part number H1.5X48 when ordering; the item is sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
