Profile : Piston Seals


Spareage : P48
P48 Assembly
 
Details :
P48 is a single acting piston seal suitable for light to medium duty hydraulic cylinders & suitable for cylinders with small groove dimensions thus enabling a compact piston. The P48 is a combination of square energiser and outer seal ring made of PTFE added with a filler to increase the resistance of seal ring to high pressure. Generally, Bronze is the used as filler. But, Glass/Graphite filled PTFE seal can also be made. The P48 seal can be easily mounted on a single piece piston and is also suitable for two-piece piston application. The Bronze filled PTFE outer seal ring, when in contact the cylinder bore, the PTFE ensures a stick slip free movement and reduces friction to a minimum. The filler increases the strength in the seal ring to prevent it from extruding and to withstand pressures as high as 400 BAR.
