The rod seal is the most critical seal on any type of fluid power equipment preventing leakage of fluid from within the cylinder to the outside. Leakage through the rod seal can reduce equipment performance, and also in extreme cases can cause environmental issues.
PTFE piston seals (PTFE rod seals) as Spring-energized seals and memory packings are always the ideal choice for sealing static or dynamic pistons and rods.
