Hydraulic Seals And Pneumatic Seals

Engineered Polymer Solutions for Hydraulic, Pneumatic, and Rotating Equipments
 
Chesterton'" positive rake wipers are designed to effectively clean and dislodge foreign matter from retracting rods or rams to prevent scoring and system contamination. The sharp, rugged, flared profile provides protection against abrasive particles which can con - taminate the system and lead to premature equipment failure. These wipers provide excellent performance on rods or rams in hydraulic and pneumatic applications. The 21 K 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. The SK Super Wiper is made from a compression molding process that utilizes existing tooling. Additional custom designs were developed to meet specific application and equipment needs which include snap-in, stepped, and bi-directional wipers.

Rod Seals and Piston Seals

 
Chesterton" 1 OK Super Monoseal" and 22KN are single-acting, U-cup designs. The positive rake, lip profile provides an optimal amount of radial sealing load with minimal frictional resistance. This seal design is offered as a rod or piston seal and provides outstanding performance in both hydraulic and pneumatic applications. The 1 OK Super Monoseal" is made from a custom molding process that utilizes existing tooling. The 22KN design is manufactured using a machining process which allows the flexibility to create any size based on equipment dimensions. A number of unique designs have been derived from the originall OK to address specific needs and applications in the market. These include designs to address pressure reversal, pressure spikes, and system vacuuming.

Ancillary Devices

Chesterton" 9K anti-extrusion rings, often referred to as back-up rings, are designed to prevent seals or O-rings from extruding into equipment clearances while under pres- sure. Each ring is individually manufactured and provides excellent performance, as a supporting element, to both piston, rod and face seals that are generally found in static or dynamic applications.

Chesterton" 9K anti-extrusion rings, utilize a machining process to create a final product which enables all sizes to be made to equipment dimensions. These anti-extrusion rings are available in various extrusion-resistant materials and are located on the back-side or low pressure side of the sealing element they are supporting. Anti-extrusion rings are available in many materials and custom profiles including rectangular, contoured, con-tinuous or split designs.
