PRODUCT DESCRIPTION

The double-acting K70 is composed of an extrusion-resistant sealing element made of blue TPU 95, which is prestressed by an O-ring made of NBR 70. If there is pressure on both sides, two sealing edges establish a secure media separation.

PRODUCT ADVANTAGES

• The sealing material polyurethane (TPU) stands out for its high wear and extrusion resistance as well as its compression set
• Nitrile butadiene rubber (NBR) and TPU are resistant to hydraulic oils in accordance with DIN 51524 (Part 1-3) and flame-resistant hydraulic fluids (HFA, HFB, HFC), along with lubricating oils and greases based on petroleum oils
• Channels on the facing surface ensure a rapid pressure build-up
• Rounded sealing edge provide a hydrodynamic lubricating film and reduced friction
• Economical profile thanks to the O-Ring as energizer and both direct activated sealing edges
• Very low mounting effort
