PTA is a double acting piston seal suitable for light to medium duty hydraulic cylinders & suitable for cylinders with small groove dimensions thus enabling a compact piston.
The PTA is a combination of NBR O’Ring energiser & 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 filler. But, Glass/Graphite filled PTFE PTA compact seal can also be made. The PTA 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 & reduces friction to a minimum. The filler increases the strength in the seal ring to prevent it from extruding & to withstand pressures as high as 400 BAR.
