Types of Symmetric Seals
U-Cups/U-Rings
Many U-cup designs are inherently symmetric.
Compact Seals
Some compact seal designs offer symmetric sealing.
Specialized Lip Seals
Lip seals with specific lip profiles designed for symmetric sealing.
O-Rings
Can function as symmetric seals in certain applications.
Nitrile Rubber (NBR)
Viton (FKM)
For higher temperature and chemically aggressive environments.
Polyurethane (PU)
For applications requiring good abrasion and tear resistance.
Silicone
For applications requiring flexibility and temperature resistance.
PTFE (Teflon)
For low friction and chemical inertness.
Applications
Hydraulic Cylinders
Especially in double-acting cylinders where pressure is applied to both sides of the piston.
Pneumatic Actuators
In systems with reciprocating or oscillating motion.
Valves
Where sealing is required in both directions.
Key Features and Benefits
Bi-Directional Sealing
Seals effectively in both directions, simplifying design and installation.
Versatility
Suitable for a wide range of applications with reciprocating or oscillating motion.
Simplified Installation
No need to worry about seal orientation during installation.
Reduced Inventory
One seal can often replace two different seals (one for each direction) in some applications.
