TRC4 - Valve

Part number TRC4 is a high-pressure aircraft tire and strut valve core (Schrader-type), used in aircraft wheel assemblies, landing gear oleo struts, and other aerospace pneumatic charging applications. It is the aviation-industry standard valve core designed for significantly higher pressures than automotive valve cores.
