PRODUCT DESCRIPTION

The single-acting rod seal S72 consists of an extrusion and wear-resistant TPU sealing element and a POM back-up ring, which protects against gap extrusion at high pressures and temperatures. These characteristics are the basic requirements for functional, long-lasting sealing solutions.

PRODUCT ADVANTAGES

• The sealing material polyurethane (TPU) stands out for its high wear and extrusion resistance as well as its compression set
• The back-up ring made of polyoxymethylene (POM) prevents gap extrusion at high temperatures and pressures
• TPU is 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 surfaces ensure a rapid pressure buildup
• Channels on the seal's backside allow a direct media backflow
• The sealing lip can bring about a pressure release in the event of an excessive pressure build-up
• Very low mounting effort
