ABOUT O-RING

An O ring is a solid-rubber seal shaped like a doughnut or torus. When compressed between mating surfaces, an O ring blocks the passage of liquids or gases. O rings are available in a wide range of standard and non-standard sizes that are suitable for nearly all sealing applications. The O ring are describe by two dimensions size which is its inside diameter (ID) and its cross-sectional diameter (CS).

O-RING TYPES

Large inventory of O ring including every standard AS-568A size, with I.D.’s ranging from 1/32″ (.794mm) to 26″ (66.04cm), O.D.’s ranging from 3/32″ (2.38mm) to 26-1/2″ (67.31cm) and cross sections (widths) ranging from 1/32″ (.794mm) to 1/4″ (6.35mm). Metrics and non-standard sizes are available. O-rings in various sizes and compounds. O-ring kit in assorted sizes.

Stocked O Ring of different elastomers and durometers:

•Nitrile (Buna), 70-90 durometers
