Product finder
Our comprehensive product range is designed to meet your operational requirements, complemented by customized sealing solutions for specialized applications.

01
Rod seals protect the most visible failure point of hydraulic cylinders.

02
Piston seals manage pressure between the piston and cylinder bore.

03
Wiper seals keep dust, mud, moisture, and abrasive particles away from the rod seal.

04
Wear rings guide rods and pistons, absorb side-load, and help protect sealing surfaces.

05
O-rings handle static and selected dynamic sealing needs, while backup rings support extrusion resistance.

06
Rotary sealing depends on speed, shaft finish, media, temperature, and pressure.
