Hydraulic seals, Piston Seals , Oil Seals Manufacturer Supplier for over 20 years .
DSH Piston Hydraulic Ring further development of the standard DAQ, the double-acting incorporates an elastomer. Quad ring seal and an elastomer or polyurethane Bean Seal in the dynamic sealing face. It is energized by two O-Rings to improve sealing behavior. DAQ commonly used in piston accumulators and medium-duty hydraulic cylinders.
DSH Seals DAQ have a nitrile rubber (NBR) O-ring energizer. The PTFE slide ring incorporates an NBR X-ring to improve sealing performance. They are suitable for pressures up to 40Mpa in medium to heavy duty applications.
high sealing effect in applications requiring media separation.
Double security through the combination of low-friction special materials with
elastomer seals.
Simple groove design, small installation space, inter-changeable with Glyd Ring
and Step seal.
Outstanding sliding properties, no stick-slip effect.
