WEH® Connector TW141

For Straight Tube OD | Lever Actuation | Vacuum up to 100 bar

The WEH® TW141 Quick Connector is designed for fast, secure pressure, function, and leak testing of straight tubes (OD 6.0 mm to 22.2 mm). It also supports the charging of closed cooling circuits with refrigerants. No tools, hand tightening, or additional sealants are required — connect and seal in seconds using a simple lever actuation.

Its jaw locking mechanism ensures low surface pressure and minimal deformation, while internal pressure support prevents disconnection under pressure, enhancing operator safety.
