J1438P127
FAA 8130-3 certified: Supplied with traceable paperwork suitable for inclusion in certified maintenance records.
OEM-dimensioned: Manufactured to the original form and fit so it drops into the designed gland or groove without modification.
Good compressibility: Conforms to mating surfaces to form a consistent seal with modest assembly force.
Low extrusion tendency: Engineered to remain in the gland under normal system pressures when installed correctly.
Seals the piston or rod gland during actuator overhauls and routine maintenance.
Prevents oil leakage from pump casings during bench testing and in-service operation.
Provides shaft/stem sealing in control and isolation valves within hydraulic and pneumatic systems.
Used to seal removable ports and fittings during fuel-system servicing when OEM specifies.
What exactly is this packing used for?
It is a replaceable sealing element used in glands or grooves to prevent fluid or air from leaking between mating parts.
How do I install it correctly?
Follow the aircraft or equipment AMM. Clean mating surfaces, seat the packing evenly in the gland, and use any specified lubrication or installation tools.
Can I reuse the packing after removal?
Generally, packing is replaced when disturbed. Reuse is only acceptable if the AMM/OEM explicitly permits it and the packing passes inspection.
