Safe, reliable and pressure-tight connections can save time and money by boosting efficiency during leak and pressure tests and filling of gaseous material. WEH’s quick-release couplings allow for safe and easy pressure and leak testing during series production of automotive components. The high-quality couplings connect in seconds to threads, tubes, bores, beads, collars, flanges, etc. And all without tedious hand tightening, thereby simplifying testing and reducing connection time. The productivity is increased and testing of fuel lines, engines, steering and braking systems made easy.
