Zoro Select O-Ring 15 mm ID 1 mm Buna-N Black PK50

Industrial sealing component

The Zoro Select Buna-N O-ring kit supplies fifty identical rings with a 15 mm inside diameter and 1 mm cross-section for maintenance technicians who need reliable static or dynamic seals in metric-dimensioned equipment. Each ring is manufactured to a 70A durometer hardness and coloured black for quick visual identification in parts bins.

Fits standard 15 mm grooves

The round cross-section seats directly into a 15 mm nominal groove without shims or adapters, while the 17 mm outside diameter fills the gland completely. Buna-N material resists common hydraulic fluids, lubricating oils and water-glycol mixtures, so the same part number covers multiple fluid circuits across a workshop.

Consistent compression over temperature

Rated from -40 to 250 degrees F, the medium-hard compound maintains sealing force during cold starts and sustained heat cycles without permanent set. FDA-approved formulation also permits incidental food-contact use, and the metal-detectable additive supports contamination-control programmes that rely on inline detection rather than X-ray inspection.
