Wiper Seals

Explore our wide range of high-performance wiper seals, an essential element for the correct functioning of both hydraulic and pneumatic systems.

Reliable Wiper Seal Performance for Contamination Prevention

A wiper’s primary role is to clean the rod or ram of a cylinder, removing dirt, moisture, and other contaminants before they can enter the system. Its performance is critical to the reliability of hydraulic and pneumatic systems and is heavily influenced by the quality and efficiency of the surrounding seal.

Also known as dust seals, scraper seals and excluder seals, wiper seals effectively prevent contamination by blocking debris and moisture from entering the system, preventing premature wear within the system or extensive damage to the rod and cylinder.

Wiper Seals We Supply

Explore our range of wiper seals, suited to a range of hydraulic and pneumatic applications.

Chesterton® 21K Canned Wiper Seal

A positive-rake canned wiper designed to effectively clean and dislodge foreign matter from retracting rods/rams to prevent scoring and system contamination in open-cavity hydraulic applications. This wiper provides excellent performance for hydraulic and pneumatic applications.

Chesterton® 21K Wiper Seal

This positive-rake wiper is designed to effectively clean and dislodge foreign matter from retracting rods and rams to prevent scoring and system contamination. The sharp, rugged, flared profile provides protection against abrasive particles which can contaminate the system and lead to premature equipment failure. These wipers provide excellent performance for hydraulic and pneumatic applications.

Chesterton® 5K Wiper Seal

A positive-rake wiper engineered to efficiently remove debris and contaminants from retracting rods and rams, helping to prevent scoring and system infiltration. Its sharp, durable flared design shields against abrasive particles that can cause early equipment wear or failure. Ideal for delivering reliable performance in both hydraulic and pneumatic systems.

Engineered for Maximum Protection

Wiper seals are designed with a precision scraping lip that removes contaminants from the rod or ram during the retraction stroke, preventing debris from entering the system. The most effective wiper seals feature a positive rake profile—a proven geometry that not only clears away foreign matter efficiently but also helps reduce rod scoring.

For a wiper seal to perform effectively, the sealing lip must maintain a tight interference fit around the rod, ensuring protection both at rest and during operation. This requires the inner diameter of the seal to be slightly smaller than the rod itself. For applications involving stubborn contaminants like dirt, ice, or frost, double-lipped wiper seals provide added protection with a secondary lip to enhance cleaning performance.

Robust Protection Against Environmental Contaminants

Effective wiper seal performance is essential to protecting hydraulic and pneumatic systems. Without protection against contaminants, dirt and moisture can lead to premature wear or serious damage to rods and cylinders. A seemingly simple component, the critical role of wiper seals are often underestimated.

Contamination is one of the leading causes of early seal and component failure. Choosing the right wiper seal—especially one made from advanced materials—can significantly extend mean time between failures (MTBF) and improve overall system reliability.
