Description

The 702303 O-RING 2-221 HNBR is a high-quality sealing component manufactured by Blackmer, supplied by KI Pumps of Waukesha, WI. This O-ring is constructed from hydrogenated nitrile butadiene rubber (HNBR), known for its excellent resistance to heat, oil, and compression sets, ensuring durable performance in demanding environments.

The O-ring has a standard AS568 size 2-221, designed for precise fitting in pump and valve assemblies. Its dimensions include a cross-sectional diameter of approximately 0.070 inches (1.78 mm) and an inner diameter of 0.221 inches (5.61 mm). It is compatible with equipment requiring high-pressure sealing, with an operating temperature range of -40°F to +250°F (-40°C to +121°C).

Key features include:

  • Material composition: HNBR (hydrogenated nitrile-butadiene rubber)
  • Dimensions: 2-221 (AS568 standard), cross-section 0.070 inches, inner diameter 0.221 inches
  • Temperature resistance: -40°F to +250°F (-40°C to +121°C)
  • Chemical resistance: oils, greases, hydraulic fluids, and moderate acids
  • Durability: high resistance to wear, compression set, and extrusion
