RTA is a single acting rod seal suitable for light to medium duty hydraulic cylinders & suitable for cylinders with small groove dimensions, thus enabling a compact gland.
The RTA rod seal is a combination of a NBR O’ring energiser & an inner seal ring made of PTFE added with a filler to increase the resistance of the seal ring to high pressure. Generally, Bronze is the used filler but also Glass & Graphite filled PTFE SS rod seals can be made.
The RTA seal can easily be fitted in a single gland and also suitable for a 2 piece Gland application. The Bronze filled PTFE inner seal ring, when in contact with the piston rod, the PTFE ensure a stick slip free movement & reduces friction to a minimum. Whereas the filler increase the strength in the seal ring to prevent it from extruding & to withstand pressure as high as 400 BAR.
