Colored NBR and EPDM O-Rings: Standard Sizes and Replacement Selection

Colored rubber O-rings are circular sealing elements offered in NBR and EPDM options for standard-size and drawing-based replacement inquiries. Specify the compound and dimensions for each part number; color can assist assembly identification but does not establish the material grade.

For hydraulic, pneumatic or machinery service, identify the actual fluid, temperature, pressure and whether the sealing joint moves. Wear performance depends on compound, gland fit, surface condition and lubrication. Select NBR or EPDM against the actual application rather than assuming the same ring suits every oil, gas or water exposure.
