Piston Seal Set P12

DESCRIPTION
Piston  P12 seal set is duoble acting seal for heavy duty applications.Set  P12 is consisting of one rubber energising element, PTFE modified sliding ring, and two back-up ring made in POM
High resistance to pressure with peak pressure up to 60 Mpa, good protection against axtrusion even at large radial gaps, high resistance to abrasion and low friction and without the appearance of stick-slip.

APPLICATION
Earth moving equipment
Excavators
Lifting machines
Industrial vehicles
Presses
Heavy duty cylinders
