SD 139

Sealing for hydraulics and pneumatics

Epidor

Stem seals

Specifications

The DS 139 profile is a symmetrical single-acting seal. Both the inner and outer lip edges exert the same sealing force and can therefore be used as a rod seal or piston seal.
Part recommended for low pressure hydraulic cylinders or pneumatic cylinders.
- Part for pneumatics and low pressure hydraulics.
- Rod seal / piston seal.
- Spare part.
It can be machined in both polyurethane and elastomer. See materials section.
