Product description

Screw seals = leather rings. Metal washers of rectangular cross-section with a ring of vulcanized rubber with a trapezoid-shaped cross-section glued to the inside. An improvement on the original concept, the self-centered bonded seal offers a further increase in utility.

  • The seal is designed for high pressure environments where copper washers are inadequate.

Washer and rubber material can be selected as required. Available in a complete metric and inch size range.

Material

Nitrile - NBR

Elastomer resistant to mineral oils, water and watery liquids, hot air and numerous chemicals.

  • It is a multi-purpose rubber suitable for a wide range of applications.
  • Temperatures from -30 °C to 110 °C

Fluorocarbon

Fluorocarbon elastomer resistant to mineral oils, gasoline and a wide range of solvents and chemicals. In this respect it outperforms other oil resistant materials (e.g. NBR).

  • For temperatures from -25 °C to 250 °C

Hydrogenated nitrile - HNBR

HNBR has higher tensile strength and abrasion resistance than NBR, and five times the resistance to acid gasoline, acid gas and ozone.

  • Highly effective in oil wells with resistance to heat, hydrogen sulfide, corrosion inhibitor, oil and steam.
  • Wide application in automotive and petroleum industries.
  • Permanent use from -30 °C to 150 °C (10,000 hours).
