Screw seal = usit rings
Metal washers of rectangular cross-section with a vulcanized rubber ring with a trapezoid-shaped cross-section bonded to the inner side.

  • Improvement of the original concept is a self-centered bonded seal that offers additional benefits.
  • The seal is designed for high pressure environments where copper washers are inadequate.

The washer and rubber material can be selected as required.
It is available in full dimensional range, both in metric and imperial units.

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.
  • For temperatures between -30 °C and +110 °C
Fluorocarbon
Fluorocarbon elastomer resistant to mineral oils, petrols and a wide range of solvents and chemicals. In this respect it is superior to other oil-resistant materials (e.g. NBR).
  • For temperatures between -25 °C and +250 °C
Hydrogenated nitrile - HNBR
Compared to NBR the HNBR has higher tensile strength and abrasion resistance, five times higher resistance to acidic petrol, acidic gas and ozone.
  • Highly effective in oil wells for its resistance to heat,hydrogen sulfide, corrosion inhibitor, oil and steam.
  • Wide application in the automotive and petroleum industries.
  • Permanent use between -30 °C and +150 °C (10 000 hours).
