Characteristics and performance

The Hallite 003 Polyurethane O-Ring (PU O-Ring) is an excellent compact solution for your static applications. It is an effective singular solution versus a two-piece component when the space for a seal in the cylinder is limited. Its key benefits include:

  • Less risk of assembly errors
  • Less space required
  • Less purchase and stock handling needed

Product details

The O-Rings fit traditional and industry normal O-Ring grooves. Please refer to datasheet for more information.
