Project Description

Bonded Seal(Dowty Seal) is a washer used to seal around a bolt or screw. These seals are available in metric and inch dimension. Bonded Seal(Dowty Seal) consist an outer annular ring of steel and an inner ring of elastomeric material. An inner ring of elastomeric material is known as a gasket. Dowty Seal acts as sealing discs which seal threads and flange joints. Bonded seals are high-pressure seal used in hydraulic, pneumatic, and mechanical sectors. The metal washer in bonded seal prevents over compression and limits deformation of the elastomeric ring(gasket).

  • Ideal Pressure Gasket.
  • Reliable sealing at high & low pressure.
  • High & low temperature capability.
  • Reduced bolt torque with no loss of tightening loads.
  • Metal ring prevents rubber compression.

The most common washer types are Mild Steel or Stainless steel. Other more unusual metals can be supplied. Different combinations of metal washer and rubber sealing elements can be produced.

Bonded Seals are available in a choice of materials including:

  • Metal.
  • MS.
  • SS.
  • Brass.
  • Aluminium.
  • Rubba
  • NBR
  • Viton.
  • EPDM.
