The WEH TW111 connector is now available with a reduced outside diameter of only 25 mm.
It is specifically designed for filling and maintenance of refrigeration and air conditioning systems and plants. Compared to conventional screwed connectors, the escape of refrigerants from the WEH connector during connection and disconnection is reduced by 99 %. Thus saving costs - and far more importantly - our environment.
RSI resulting in the inflammation of tendons and abrasion of joints caused by continuous screwing and unscrewing of threaded joints is eliminated. Connection and disconnection is effected by a simple movement of the grip sleeve. The integrated shut-off valve prevents the escape of refrigerant which remains in the filling tube and can then be correctly disposed of.
The type TW111 is equipped with a UNF 7/16“-20 thread (equivalent to 1/4“ – SAE tube connection) and is either available for high pressure (red grip sleeve) or for low pressure (blue grip sleeve).

The type TW111 is also available with 90° media inlet.
