High pressure test bench couplings THL

Designed for very frequent use, i.e. up to 10,000 unpressurized connections, THL quick couplings ensure a consistent and reliable mechanical connection. They are also completely leak-tight: sealing is metal to metal , so no seal is needed between the product and customer interface. Push-button lock for easy disconnection saves time between tests.

Application: High pressure test bench
