Description

Professional Buna-N O-Ring designed for static and low-pressure sealing in oil-based hydraulic and mechanical systems. Its compact geometry enables tight tolerances in small assemblies, with a 28 millimeter inside diameter and a 1 millimeter cross-section.

Specs

  • Product type: O-ring seal
  • Dimensions: Inside diameter 28 millimeters; Cross-section 1 millimeter
  • Material grade: Buna-N 70 (Nitrile Rubber)
  • Durometer: 70 Shore A
  • Packaging: 50 seals per pack; bulk packaging

Features

  • Oil- and fuel-resistance: Buna-N 70 formulation provides reliable sealing across mineral oils and hydrocarbon-based fluids in hydraulic and mechanical assemblies.
  • Static and low-pressure sealing: Optimized for fixed interfaces and low-fluid-pressure environments, reducing leakage risk in assemblies subject to steady-state operation.
  • Compact geometry: 28 millimeter inner diameter with a 1 millimeter cross-section enables tighter tolerances and smaller overall package footprints.
  • Bulk packaging support: Pack quantity of 50 seals facilitates batch processing, inventory control, and consistent re-supply for manufacturing lines.
  • Material compatibility: Nitrile-based elastomer optimized for oil-based systems, offering good compression set characteristics under typical operating temperatures observed in mechanical seals.
