Seal profiles for piston and rod applications
Symmetric hydraulic seals can be used as piston seals or rod seals depending on the installation situation. Thanks to their symmetric profile, they are suitable for both externally sealing and internally sealing applications in hydraulic systems.
Which design is the right one depends on the specific operating conditions. Key factors include installation position, sliding speed, pressure load, medium, and temperature.

Symmetric hydraulic seals from INNSEALS
Symmetric hydraulic seals are versatile sealing elements for hydraulic applications. Depending on the installation, they are used either for sealing on the piston or on the piston rod.
As piston seals, they provide external sealing. As rod seals, they perform an internal sealing function. This makes them particularly suitable for applications requiring a compact, universally usable seal profile.
Symmetric hydraulic seals in the sealing system
Symmetric hydraulic seals often work together with guide elements, wipers, and other sealing elements. Guide elements stabilize the piston or piston rod, while the seal provides the sealing function.
Reliable function is achieved through the right interaction of profile, material, installation space, and operating conditions.

Your FAQs answered
Frequently asked questions:
Symmetric hydraulic seals have an identical geometry on both sides. This allows flexible installation and reduces the risk of assembly errors.
Yes, many symmetric seals are designed so that they can be used in both piston and rod applications.
The identical shape on both sides eliminates the need to check installation direction. This simplifies assembly and saves time, especially in series installations.
Yes, they offer comparable sealing performance in many applications. However, suitability depends on the specific operating conditions.
They are used in mechanical engineering, hydraulic systems and industrial plants where easy assembly and flexible deployment options are required.
