The GARTHANE® 9220 U-Seal is a tough urethane seal with excellent tear and abrasion resistance.
Garlock GARTHANE® 9220 U-Seals have four times the tensile strength and tear resistance of conventional seals and can withstand shocks over a wide range of temperatures, chemicals, and pressures. They also demonstrate outstanding endurance under difficult operating conditions. These seals are ideal for plungers, pistons, rams, and rods.
FEATURES and BENEFITS
- Increased seal life and performances
- Eliminates chance of costly premature equipment failure
- 90 Durometer Urethane – High tensile strength and tear resistance
- Reverse bevel lip design – Less friction and responds immediately to pressure
- Balanced Design – Can function as a rod or piston seal
- Extensive tooling list – Greater size availability-both inch and metric
- Four times the tensile strength/tear resistance of conventional seals
- High modulus counteracts extrusion and shear forces
- Withstands shocks over a wide range of temperatures and pressures
- Exceptional abrasion resistance
- Outstanding endurance under difficult operating conditions
- Excellent elasticity and resilience
- Withstands high degree of deformation
- Excellent for use against petroleum based fluids to 225°F / 107°C; air, warm water, and water glycol to 180°F / 82°C
