Threadless connections -plug-in systems - are becoming more and important for the layout of new hydraulic systems. The connection technology is an important cost factor for pipeline systems. A simple and effective solution such as STH-P provides a large saving potential. In addition to that, STH-P provides a unique combination of all benefits of a modern plug-in system and at the same time the guarantee of million fold use due to the proven connection technology.

• Simple connection plug-in connector
  Applying of the connector by roller-burnishing No assembly at the plug-in connector, as all components are pre-assembled in the plug-in socket
• Considerable reduction of assembly time
  Simple connection instead of screwing in
• Optimized design of constructed space by minimized space requirements
  No assembly tools are necessary, disassembly with a small extraction tool
• Saving potential by reduction of components
  New connection components allow a reduction of number of components as well as of the total weight
• Reliably sealed hydraulic system
  The patented 2-ring locking system excludes leaks caused by over- or under-assembly
• A connection technology confirmed by the market
  Millions of this connection technology are used

STH-P the hydraulic plug-in system by SCHÄFER
The system was developed to connect fluid-carrying tubes with each other. The necessary contours for the use of the plug-in system can be independently roller-burnished for the male component by the customer according to the specifications of Schäfer. All components of the plug-in system are integrated in the plug-in socket (female connection component). In the delivery condition, only the protective cap of the plug-in socket has to be removed, after this it can immediately be plugged in. While plugging in initially, the retaining ring is put in the plug-in socket on the retaining ring notch at the tube and remains there permanently, even if the connection is released. The plug-in connection can be released easily with a separate removal tool (see illustration).
