Polymer Seals Catalog Polymer Seals Polymer Seals Catalog Polymer Seals Wiper The function of a wiper is to effectively clean and to dislodge foreign matter from a reciprocating rod/ram to prevent contaminants from entering the system. Rod Seal The function of a rod seal is to act as a pressure barrier and prevent fluid bypass along the dynamic (rod/ram) surface and the static (stuffing box bore) surface under various operating conditions. It regulates the fluid film during extension of the cylinder rod. Buffer Seal The buffer seal reduces the impact of pressure spikes on the secondary rod...

Hydraulic and Pneumatic Seals – Wiper Seals Polymer Seals Catalog Protect the System from Entering Contaminants Chesterton positive rake wipers are designed to effectively clean and dislodge foreign matter from retracting rods or rams thus preventing 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. Single- and double-acting wiper designs are available...

Hydraulic and Pneumatic Seals – Wiper Seals Polymer Seals Catalog CW21K Canned Wiper Seals Protect the System from Entering Contaminants Chesterton positive rake wipers effectively clean and dislodge foreign matter from retracting rods or rams thus mitigating scoring and system contamination in open cavity designs. These wipers provide excellent performance for hydraulic applications. Canned wiper seals require an open, easy construction groove. It helps to simplify gland design, layout, and manufacturing. Another advantage is the possible space savings, as shorter space is required for...
