Description
This Hydraulic Compact Rod Seal GSW is composed of a rubber O-ring and a PTFE ring. The material is PTFE+NBR. In special cases, the rubber will be used FKM. It is suitable for rods in hydraulic cylinders. The rod seal ensures that when the rod circulates back and forth in the gland, the pressurized fluid will not leak out of the system.
The installation's physical performance of this Hydraulic Compact Rod Seals GSW is stable. It also has a good dust-proof effect and is not easy to be invaded by foreign objects. Furthermore, it can prevent all external interference. It is applicable to high and low-speed reciprocating motion environments, a wide range of fluids, and high-temperature conditions. Suitable for a larger gap of the piston rod. Low friction and simple groove make it be able to work in the medium with oil spots.
