Product catalog
Seal families organized by function, not guesswork.
Identify the product family, then send dimensions, operating details, drawing, or sample photos for profile and material guidance.
Cross-sectionMaterial stack
01
Rod seals
Rod seals protect the most visible failure point of hydraulic cylinders.
02
Piston seals
Piston seals manage pressure between the piston and cylinder bore.
03
Wiper seals
Wiper seals keep dust, mud, moisture, and abrasive particles away from the rod seal.
04
Wear rings
Wear rings guide rods and pistons, absorb side-load, and help protect sealing surfaces.
05
O-rings & backup rings
O-rings handle static and selected dynamic sealing needs, while backup rings support extrusion resistance.
06
Rotary seals
Rotary sealing depends on speed, shaft finish, media, temperature, and pressure.
07
Custom profiles
Not every sealing problem fits a standard catalog profile.

Selection signals engineers actually look for.
| Need | Likely family | What to confirm |
|---|---|---|
| External leakage control | Materials | Rod diameter, groove, pressure, speed, media. |
| Pressure separation | Piston seals | Bore, action type, extrusion gap, temperature. |
| Dust and moisture exclusion | Wipers | Environment, rod finish, installation style. |
| Side-load guidance | Wear rings | Load, clearance, material pairing, cylinder size. |
| Static sealing or extrusion support | O-rings & backup rings | Media, groove, pressure, temperature. |
