Product Specification

-
Ordered as H2X17.5, this is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 17.5 mm (0.689 in), a cross section of 2 mm (0.079 in), and an outside diameter of 21.5 mm (0.85 in). The o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to greases and lubricants, many alcohols, and propane and butane. Buna-N (Nitrile) is widely chosen for the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Verify compatibility before use with ozone and direct sunlight or automotive brake fluid.

Typical settings include fluid power, general industrial maintenance, and construction equipment.

Reference part number H2X17.5 when ordering; the item is sold individually. Unit weight is approximately 0.244 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
