Double Delta Seal Light Load Hydraulic Piston Seal PDD
The PDD Double Delta is a double-acting piston seal suitable for light to medium-duty industrial hydraulics and pneumatics equipment, also applications with small diameter groove design. It provides low-friction performance in a compact design for medium pressure operating conditions. It's a clever upgrade to conventional sealing arrangements and is made to fit standard o-ring grooves. Its optimised profile reduces drag forces in back-to-back and double-acting piston arrangements, helping to separate different media while still providing reliable sealing. It makes it compatible to a wide temperature and fluid range due to different material options. Snap-in construction allows quick and easy installation for larger rod diameters.
