  • Viton material resists -15 to 400 °F

  • Medium-hard 75A durometer balances strength and flexibility

Square Profile Viton O-Ring Pack

This pack contains 25 square-profile Viton O-rings in dash size 012 for static sealing applications. The rectangular cross-section design provides reliable sealing in hydraulic and pneumatic systems where standard round O-rings may roll or twist. Each ring is manufactured to precise dimensional tolerances for consistent performance across the batch.

Medium Hard 75A Durometer Performance

The Viton material carries a 75A durometer rating that resists extrusion under pressure while maintaining elasticity through thermal cycles. Operating temperature range spans from -15°F to 400°F, covering most industrial fluid and gas media. The medium-hard compound balances compression set resistance with installation compliance for long service intervals.

FDA Approved Metal Detectable Design

These black O-rings are FDA approved and metal detectable for use in food, beverage and pharmaceutical processing equipment where contamination control is mandatory. The nominal inside diameter is .3 in with .07 in actual width and .504 in actual outside diameter. Not X-ray detectable, so detection method compatibility should be verified before specification.

Questions about this item

How do I install the Zoro Select Square Profile Viton O-Ring Dash 012 without damaging the rectangular cross-section?

Press the ring evenly into the groove using a blunt tool; stretching the 0.07 in width over sharp edges cuts the Viton material and ruins the seal.

When should I replace these Viton O-rings in a high-temperature system?

Replace them once the material hardens or cracks from cycling near the 400 Degrees F limit; the 75A durometer Viton loses elasticity after prolonged heat exposure.

What is the first limitation that appears when these O-rings run continuously at the upper temperature range?

The Viton compound gradually hardens past its 75A rating, reducing compression set resistance and causing leak paths to form at the 0.3 in inside diameter.
