High Pressure Joint Gasket Seal
The Dowty Bonded Seal is a synthetic rubber sealing member that is bonded with heat and pressure to a zinc plated steel washer. The flexing action of the lips under pressure provides a positive and leakproof seal against a wide range of fluids, at , depending upon size, pressures up to 20, 000 p.s.i. (1380 bar). The Dowty Bonded Seal, in addition to eliminating leakage, reduces tooling, installation and maintenance costs. The face to face sealing they permit eliminates groove cutting or special machining and reduced bolting torque. Dowty Bonded Seals are supplied in quantity to large scale users in the aircraft, motor and electronics industries, and for specialized products ranging from navigational instruments to rock drilling equipment.
Materials & Temperature Range
The Dowty Bonded Seal is suitable for use with mineral oils, water, gases and many other fluids. The temperature range varies according to the particular application. For general conditions, the 400 Series operates from -40°F to +212°F (-40°C to +100°C)
Low Octane Fuels
The Dowty Bonded Seal is available in the full range of sizes for low octane fuels, diesel oil, etc., suitable for temperature ranges of -20°F to +240°F (-29°C to +120°C)
Tapped Holes
When bonded seals are used to seal tapped holes the thread relief should never be greater than 0.01 in. (0.25 mm) above the nominal outside diameter of the screw thread.
