ENGINEERED SOLUTIONS FOR
EVERY CHALLENGE
Our comprehensive product range is designed to meet your operational requirements, complemented by customized sealing solutions for specialized applications.
01
Rod seals
Rod seals protect the most visible failure point of hydraulic cylinders.
PU / PTFE / Elastomer
02
Piston seals
Piston seals manage pressure between the piston and cylinder bore.
PU / PTFE / NBR
03
Wiper seals
Wiper seals keep dust, mud, moisture, and abrasive particles away from the rod seal.
PU / NBR / metal caged options
04
Wear rings
Wear rings guide rods and pistons, absorb side-load, and help protect sealing surfaces.
Phenolic / POM / PTFE
05
O-rings & backup rings
O-rings handle static and selected dynamic sealing needs, while backup rings support extrusion resistance.
NBR / FKM / PTFE
06
Rotary seals
Rotary sealing depends on speed, shaft finish, media, temperature, and pressure.
NBR / FKM / PTFE
