Chesterton 21K Hydraulic and Pneumatic Wiper

The Chesterton 21K Hydraulic and Pneumatic Wiper is designed to effectively clean and dislodge foreign matter from retracting rods or rams to minimize 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 on rods or rams in hydraulic and pneumatic applications

The 21K design is manufactured using a machining process allowing the flexibility to create any size based on equipment dimensions. This design incorporates a built-in static seal on the flange to ensure contaminants do not migrate along the stationary
side of the wiper during operation. The 5K Super Wiper is made from a compression molding process that utilizes existing tooling.
Additional custom designs were developed to meet specific applications and equipment needs including snap-in, stepped, and bidirectional wipers.
