Varitef TR is an internal, single-acting sealing element, which consists of a PTFE seal and a stainless steel spring as preload element. The spring is available in a variety of steel qualities.
Varitef TR is particularly suitable for positioning cylinders with high pressures and relative slow rotation movements. Suitable for applications in the hydraulics and pneumatics, chemistry, food industry and pharmacy, for rotation and swiveling movements as well as back and forth motion.
The PTFE compound is filled with bronze or carbon graphite to improve the compressive strength. Further materials upon request.
