STH-C ALS is a further development of our connector system for high-pressure hydraulics STH-C. Hereby, the benefits of this established connection system technology are completed by an integrated non-return valve. In addition to this, the system is equipped with a release ring permanently affixed to the connector (male connection component).

• Considerable reduction of assembly time
  Simple connection instead of screwing in
• Optimized design of constructed space by minimized space requirements
  No assembly tools necessary; disassembly by using a release ring integrated in the connector
• Permanently leak-proof hydraulics system
  Leakages by under and over-tightening are eliminated due to the 2-ring interlocking technology.
• Integrated leak stop
  Allows the connection of pre-filled tubes, as well as an uncoupling of the tube without spilling the fluid inside during maintenance or repair works.

STH-C ALS, the plug-in system with leak stop by SCHÄFER
The plug-in system for a quick, safe and clean connection. The system was designed for the use in sensitive or clean work areas. The integrated non-return valve prevents spilling of the included fluid while uncoupling the connection during maintenance or repair works. Therefore, maintenance can be carried out much quicker compared with conventional connection technology. In addition to that, the plug-in system is also suitable for applications which include pre-filled pipelines that need to be connected in the initial assembly.

• Cooling and temperature control circuits in medical devices (e.g. MRT)
• Cooling and temperature control circuits of industrial plants in controlled areas or clean rooms
• Cooling and temperature control circuits in the automotive industry (chassis, steering, clutch etc.)
