    WEH® TW52 | CO2 High Pressure Quick Connect
    Instant connection to your male cylinder valve thread ( G1/2", TR21x4,5 or W21,8x1/14"). Designed for high pressure up to max. 250 bar and for filling of CO2 or refrigerants.
Description
WEH® Connector TW52 for non-residual pressure valves with male thread W21,8x1/14", CO2 /refrigerants, grip sleeve actuation, max. 3,600 psi 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 suitable for use with the TVCO2 linear valve and for residual-pressure valves, and for an operating pressure of up to max. 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 supply the connector in versions suitable for other connection ports, including BS, NF, CGA, etc., for non-residual pressure valves and with linear valve.
