WEH® Connector TW850

For High-Pressure Testing up to 630 bar
Grip Sleeve Actuation For Beads, Rims, Collars, Flanges, Stubs & Male Threads

The WEH® TW850 Leak Test Connector is a rugged, high-performance quick connector designed for pressure, function, and leak testing of components with bead, rim, collar, flange, stub, or external thread—withstanding pressures up to 630 bar (9,135 psi).

With its manual grip sleeve actuation, the TW850 creates a secure and leak-tight connection in seconds—no sealants, tapes, or hand-tightening tools required. Its rapid operation significantly reduces test cycle times, streamlining testing procedures in high-pressure environments.

Built from corrosion-resistant stainless steel and equipped with a durable NBR front seal, the TW850 is engineered to withstand demanding industrial applications and is suitable for manual and automated test setups.
