Product Description
The 126m204 is a large mast gasket that seals the interface between an antenna mast and aircraft skin. This elastomeric seal prevents moisture ingress at the mounting footprint while maintaining electrical bonding between the mast and airframe. Installed at antenna mast bases on general aviation and commercial aircraft, the gasket compresses under fastener load to create a weathertight barrier.
Follow aircraft maintenance manual or STC instructions for installation, torque specifications, and sealant application per FAA AC 43.13-2B guidance.
