There are also detailed examples of seal failures and their causes, inspection checklists, installation tools and kits within the Hydraulic and Pneumatic Seals catalogue.
O-rings used in mechanical seals, connectors, valves and pumps are available from Fluid Seals. Bonded washers replace copper washers in high-pressure hydraulic systems. Using rod wipers to exclude contamination from the operating system will extend seal life in hydraulic and pneumatic rams.
