Add to Compare
  • Suitable for filling of CO₂ or refrigerants
  • Connection in seconds - Just PUSH to connect
  • No tapes, no thread sealants, no hand tightening required
  • High safety due to pressure-assisted piston
  • Environmentally friendly - a vent pipe recirculates the vented gas (in conjunction with TVCO₂)

    WEH® TW52 | CO2 High Pressure Quick Connect
    The WEH® Gas Filling Connector TW52 (with or without a residual pressure valve) has been developed especially for filling gas cylinders with gaseous or liquid CO2 or refrigerants. Connection to the cylinder is made within seconds without tedious screwing and unscrewing, thus preventing RSI resulting in the inflammation of tendons and abrasion of joints. This quick coupling is available for gas cylinder valves acc. to DIN, BS, NG, CGA, etc.

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. It is fitted with a TVCO2 linear valve, suitable for use with residual pressure valves and at an operating pressure of up to 2,175 psi (150 bar).

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.

The filling connection is particularly environmentally friendly when used together with the TVCO2 linear valve. The valve allows you to bleed back and carefully dispose of residual gas and to control the filling procedure and stop it if necessary. The TVCO2 is simply screwed onto the pressure inlet of the connector and the residual gas produced by the venting process can be fully vented via venting hose. This means that almost no CO2 is released in an uncontrolled manner into the atmosphere.

The quick connector is suitable for gas cylinder valves conforming to DIN 477. On request we can provide the connector for other connection ports, such as BS, NF, CGA etc., for non-residual pressure valves and for systems not using linear valves.
