The WEH product range for the refrigeration and air conditioning industry has been extended by the addition of a further connector for filling R410A refrigerant. The WEH TW111 connector is specifically designed for filling and maintenance of refrigeration and air conditioning systems and plants with ‚Schrader valves‘ which need to be connected and disconnected under pressures up to a maximum of 42 bar.
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 the R410A refrigerant which remains in the filling tube and can then be correctly disposed of.
The type TW111 for R410A is equipped with an UNF 1/2Pressure-tight connection in seconds“-20 (equivalent to 3/8“ – SAE tube connection) and is either available for high pressure (red grip sleeve) or for low pressure (blue grip sleeve.
