Product Description
The 402ah is a metal valve core for aircraft pneumatic inflation valves. This spring-loaded, self-sealing component installs inside a threaded valve stem to maintain tire and inner-tube pressure while allowing controlled inflation and deflation during service. The compact design prevents air leakage when not in use.
Install in compatible wheel valve stems per the aircraft maintenance manual, then leak-check after inflation to verify proper seating and pressure retention.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
