DP Seals can now count the new double-decker Airbus A380 among the blue chip users of its precision products. Following an extensive development programme in conjunction with FR-HiTEMP, DP Seals is delivering rubber diaphragms for use in the aircraft’s galley waste system.
Produced to demanding aerospace specifications from a specifically formulated EPDM (ethylene propylene) rubber, the diaphragms provide optimum leak resistance and durability in a wide range of fluctuating temperature, pressure and operating conditions. The wall of the diaphragm is just 0.3mm thick with a rolled edge.
These diaphragms are already installed in over 6,000 FR-HiTEMP drain valves currently in service on Airbus A320 and A330/340 aircraft.
