Zoro Select FFKM O-Ring 3/8" ID

The Zoro Select ZUSADC75012 is a black FFKM O-ring designed for sealing applications requiring broad chemical resistance and high-temperature stability. It suits maintenance engineers and process technicians who need a reliable elastomer seal for aggressive fluid or gas systems.

Temperature range 30 to 600 °F and 75A durometer

The seal operates continuously from 30 °F to 600 °F with a medium-hard 75A durometer that resists extrusion in dynamic or static glands. FFKM material handles most acids, bases, solvents and hydrocarbons, but it is not metal detectable, not X-ray detectable and not FDA compliant for direct food contact.

Dash 012 dimensions 0.3 in ID 0.07 in width

Actual inside diameter measures 0.3 in, actual width 0.07 in and actual outside diameter 0.504 in, matching the standard dash 012 envelope. The inch-series round cross section fits existing 3/8 in nominal ID grooves without re-machining, freeing designers from sourcing custom tooling for high-temperature sealing.

Questions about this item

Will the 0.3 in inside diameter of this O-ring match the 3/8 in groove on my existing fitting?

Yes, the nominal inside diameter is 3/8 in and the actual inside diameter is 0.3 in, so it fits a standard 3/8 in groove.

How can I confirm the FFKM material is seated correctly after installation?

Check that the black O-ring sits evenly in the groove with no twists, and verify the 0.07 in actual width fills the 1/16 in cross-section uniformly.

Does the box contain only the ZUSADC75012 O-ring or are lubricant and installation tools included?

Only the FFKM O-ring is supplied; any compatible lubricant or installation tools must be purchased separately.
