  • Ready for metric assemblies with 60 mm inside diameter
  • Withstands -40 °F to 250 °F thanks to 70A Buna-N

Zoro Select Buna-N O-Ring Pack

This pack contains ten black O-rings made from Buna-N rubber with a 70A durometer rating. They are designed for metric sealing applications where oil and fuel resistance are required. Each ring is FDA approved and metal detectable but not X-ray detectable. The operating temperature range spans from -40 degrees to 250 degrees F.

60 mm Inside Diameter Fit

The nominal and actual inside diameter is 60 mm with a 3 mm cross-section width. This precise metric sizing determines whether the seal fits your specific groove or gland. The nominal outside diameter measures 66 mm. Buyers needing a different inside diameter or cross-section thickness cannot use this size.

Ten-Piece Bulk Supply

The ten-piece pack provides enough rings for multiple replacements or small production runs. It covers standard maintenance needs for compatible metric glands. The quantity runs out quickly in high-volume assembly lines or facilities requiring larger diameter seals. This pack does not serve applications needing different materials or sizes.

Questions about this item

What does the 60 mm inside diameter mean when the O-ring is installed in a groove?

The 60 mm inside diameter matches the nominal groove diameter so the seal sits flush without stretching or pinching.

How does the 70A durometer rating affect sealing performance in a standard hydraulic system?

The medium-hard 70A durometer resists extrusion under pressure while still conforming to surface imperfections for a reliable seal.

What groove dimensions are needed to fit the 3 mm cross-section and 66 mm outside diameter?

Design the groove for a 3 mm cross-section and ensure the gland diameter accommodates the 66 mm outside diameter for proper compression.
