O-ring seal / U-shaped / rubber / piston
Max.: 1,500 bar (21,756 psi)
The Merkel Compact Seal T 42 is used as sealing pistons that can be pressured on both end of the plungers. Supplementary cylinders in self advancing support systems are very good protection from extrusion even at pressure peak. It has a high resistance to abration and it also has a high contact pressure because of the rubber profile ring.
