Product Detail
TA 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.
