VP

Oil seal characteristics: Sealed by a single-acting piston (rod) that is forced by a special spiral spring. Because of its low friction, and the preload force is quite stable in a large deformation range, the VP-type universal plug seal is used in friction. Must be kept within a very narrow tolerance range, such as in the case of a pressure switch.
