The bleeder valves consist of a bleeder needle, bleeder seat, needle cap, and in some cases an O-ring.
Bleeder seats are precision manufactured from stainless steel for corrosion resistance, and cadmium plated to prevent galvanic corrosion with the magnesium housing.
The bleeder needle is made from strong, heat treated 17-4 stainless steel, as compared to the original low-grade steel, preventing corrosion and rounding of the hex. The hex size has also been increased to further resist rounding of the wrench hex. Even the rubber cap is improved, with improved material to prevent cracking, and a shorter design, resulting in a more secure fit.
The new bleed valves are available in convenient kits or as individual components, and are available for shipment.
Two kits are required per aircraft
