Wipers
Wiper seals, also called scraper seals, are used to remove dirt, dust, moisture, and other contaminants from a rod as it retracts into a hydraulic or pneumatic cylinder. They are the first line of defense against contamination and help protect internal sealing components from premature wear and damage.
In demanding industrial environments, effective wiping is essential for preserving seal life, protecting system integrity, and reducing maintenance.
3D Seals offers wiper solutions suited for tough operating environments where contamination control is critical. We offer a complete range of Wiper series to meet industry requirements in various combinations of profiles and materials, matching a wide range of thermal, mechanical and physical properties. This includes both, standard and specialized Wipers.

Frequently Asked Questions
A wiper seal removes contaminants from the rod surface before they enter the cylinder.
The primary role of a wiper seal is contamination exclusion rather than pressure retention. However in certain cases, especially in low pressure applications, wiper seals can also work as secondary pressure seals.
They help prevent dirt and moisture from damaging internal seals, rods, and cylinder surfaces. Outside contamination are not limited to damage of cylinder componets but also damage system like valve, pumps and filter
Yes, wiper seals are available in both standard and custom dimensions.
They are widely used in hydraulic and pneumatic cylinders, especially in dirty or outdoor environments.
Wiper seals are designed to exclude contaminants and should be used together with rod seals for effective sealing. However in some case wiper works as secondary seals.
Polyurethane is commonly used due to its excellent wear resistance and durability.
