DESCRIPTION
The MPSU300 is a two-piece double-acting compact seal consisting of one polyurethane profile ring with a pronounced sealing edge and one nitrile contact pressure component for producing pre-tension.
The MPSU300 offers very good static and dynamic tightness along with low friction, smooth operation movement even at lower linear velocities. The contact pressure component with rectangular cross section prevents twisting within the groove.
