Pneumatic rod seals for internal sealing
Pneumatic rod seals are among the most important sealing elements in a pneumatic system. They seal the system on the rod side and are exposed to the full operating pressure of the application.
If a rod seal no longer functions properly, this usually becomes immediately apparent through leakage. This makes the right selection critical – depending on installation position, sliding speed, pressure load, medium, and temperature.

Pneumatic rod seals from INNSEALS
Pneumatic rod seals are used in pneumatic cylinders to seal the system internally at the piston rod. They prevent compressed air from escaping from the cylinder and are therefore critical for the tightness and function of the entire system.
Because rod seals are directly exposed to the operating pressure, the profile, material, and installation situation must be precisely matched to the application. An incorrectly selected or worn rod seal quickly leads to leakage and should be replaced promptly.
Rod seals in the pneumatic sealing system
Pneumatic rod seals work together in the system with wipers, guide elements, and other sealing elements. The wiper protects against external contamination, guide elements stabilize the piston rod, and the rod seal provides pressure-side sealing.
Only the right combination of these components ensures reliable function, low leakage, and a long service life of the pneumatic cylinder.

Your FAQs answered
Frequently asked questions:
Pneumatic rod seals seal the piston rod to the outside and prevent compressed air from escaping. At the same time they protect the system against the ingress of dirt and particles.
Yes, leaks lead to pressure loss and can negatively affect performance and the precision of movement.
Pneumatic seals are designed for lower pressures and dry media. They place greater emphasis on low friction and fast responsiveness.
Elastomers, polyurethane or special plastics are frequently used. These materials offer a good combination of flexibility and durability.
They are used in pneumatic cylinders, automation systems and industrial plants where precise and reliable movements are required.
