About Us

TST is a manufacturer of quick-connect couplings in the areas of hydraulics, pneumatics, vacuum, gas, chemical applications and water applications. This includes single couplings, multi-couplings, connecting elements, hoses and accessories.

Founded 34 years ago with headquarters in Turkey, we now have production capacity based on the latest CNC technology on an area of over 10,000 m2.

TST Europe AG took over Oetiker's coupling business in 2012 and opened a branch in Switzerland. This means that swivel couplings (SC couplings) and valve couplings (SV couplings) can continue to be delivered directly from Switzerland as usual and our customers can be supported on site. The 2-stage safety clutches are SUVA compliant. In addition, TST Europe AG is now supplying the Swiss market with water couplings, hydraulic couplings and multi-couplings from its own range.

Through the use of our leakage-free couplings in Swiss industry, we have been a partner of the Energy Switzerland campaign since 2014.
