Part number H2X64.5 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 64.5 mm (2.539 in), a cross section of 2 mm (0.079 in), and an outside diameter of 68.5 mm (2.7 in). An o-ring compresses into its gland to block fluid or gas migration across a joint. Supplementary detail from the product record: Metric O-RING, JIS S65.
The compound resists greases and lubricants, many alcohols, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with strong acids or polar solvents.
Typical settings include fluid power, agricultural equipment, and construction equipment.
H2X64.5 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
