F1 piston guide rings are open rings with axial pressure relief grooves and a retaining shoulder on the inner diameter made of thermoplastic compounds. They are easy to install, exceptionally wear-resistant and enable simple piston designs.
The F1 piston guide ring can be installed either chambered or non-chambered.

Range of application:
Guides for pistons in hydraulically or pneumatically actuated cylinders. However, for pneumatic systems, utilization is limited to service-lubricated and oiled compressed air. For dry air, we recommend our F2 product series guide tape.
