Function
The RPORA 32 is a twin-action seal consisting of a PTFE sealing element pretensioned by an O-ring. The seal is externally sealing and is normally used in a twin arrangement. The sealing surface is specially designed for use under high pressures and at low speeds. The grooves running round the dynamic sealing surface offer the possibility of creating a deposit of lubricant. This has the effect of reducing friction and enhancing emergency running properties. 

Application
The RPORA 32 is used for sealing hydraulic rotary transmission leadthroughs and for sealing swivelling or rotating pistons.
