WEH® Connector TW52 for filling of CO2 /refrigerants - Product family

Even smarter CO2 filling using the WEH® TW52 filling connector.
Specially developed for filling CO2, it works with the medium in either gaseous or liquid state. But it can also be used without problems for filling refrigerants.

The connector is designed for a pressure range of max. 250 bar, suitable for residual and non-residual pressure valves and available for male threads following various national standards: e.g. DIN, CGA, BS, NF, etc.

It adapts to cylinders in seconds – with absolutely no need for screwing.
Simply pull back the filling connector’s grip sleeve and place the connector onto the male thread of the cylinder valve until it locks into place. The WEH® jaws grip onto the cylinder thread, ensuring a pressure-tight connection. Chronic problems like wear on joints are now a thing of the past.

The filling connector is particularly suitable for filling 1-litre cylinders: such as soda cylinders, etc. for example.

Optionally, the quick connector is also available with the TVCO2 linear valve. This makes it particularly environmentally friendly, as the valve makes it possible for residual gas to be bled out and disposed of in a controlled manner, as well as allowing the filling procedure to be controlled and, if necessary, stopped.
