Metal Seals from Parker
LANDING GEAR AND WHEEL & BRAKE SEALS
Parker designed its sealing solutions for aerospace applications to withstand aggressive chemicals, including hydraulic fluids, jet fuels, engine lubricants and solvents/degreasers. Custom and standard solutons are available in a wide range of elastomeric, PTFE or labyrinth designs for engine, air management, landing gear, and wheel and brake applications.

EM163  |  METAL SEALS  |  FLEXISEALS  |  HYDRAULIC SEALS  |  ROTARY SHAFT SEALS
The critical nature of aircraft landing systems, actuation systems, wheel and brake assemblies requires a premium sealing compound to reduce frequency of maintenance and maintain the safety of all passengers.  Parker has developed EM163 to meet the ever demanding NAS1613 Rev 6 material specification.

Hydraulic Seals
Parker's extensive portfolio of sealing profiles, compounds and dimensions enables design engineers to find an ideal sealing system to meet their application needs. Custom and standard sealing solutions for landing gear, hydraulic actuators, struts, and shock absorbers are available in a wide range of polyurethane, elastomeric, and PTFE material options for seal designs.
Our hydraulic sealing products include Piston Seals, Rod Seals and Buffer Seals, Guide and Wear Rings, Guiding Tape, Wipers and O-Rings.
Hydraulic Seals
Rotary Shaft Seals
Parker's wide range of rotary shaft sealing solutions provide superior material options for improved wear resistance and enhanced performance.  Custom and standard rotary sealing solutions for wheel assemblies are available in a broad range of elastomeric and PTFE materials, as well as PTFE or metal materials for ProTech™ Bearing Isolator labyrinth seal designs. 
O-Rings
LB Rod Seal
The LB rod seal for hydraulic cylinders in aviation applications is characterized by exceptionally high static and dynamic sealing performance and high wear resistance.
It is designed for installation in grooves according to MIL-G-5514 / AS4716.
