21K Wiper
- Limits Contaminants from Entering System
Chesterton positive rake wipers are designed to effectively clean and dislodge foreign matter from retracting rods or rams to minimize scoring and system contamina-tion. 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 which allows 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.
Additional custom designs were developed to meet specific applications and equipment needs including snap-in, stepped, and bidirectional wipers.
