Complete/integrated pistons combine a metal or plastic core, bearing and seals into a single unit. Both bonded and pre-assembled versions are available. The one-piece construction reduces assembly time and part number inventory. They perform two functions: sealing and guiding. Single-acting complete pistons are designed for uni-directional pressurization and therefore provide directional drag oil performance. They show unsymmetrical cross section designs.
Parker's lip seals are single direction low load seals. When applications demand low load or low closure force on their housings and mating components, lip seals are a great solution.
Other benefits of Parker's lip seal technology:
-Ease of assembly
-Increased application pressures can be achieved
-Small or large cross sections available to fir your application
-Alternative to changing your current groove geometries
