The WEH® Gas Filling Connector TW52 has been developed especially for filling gas cylinders with gaseous and 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.
The quick coupling is also suitable for filling one litre cylinders, e.g. for soda drinks.
The TW52 is appropriated for non-residual pressure valves and rated for a pressure range of max. 250 bar.
On request you can have as option the linear valve TVCO2 (operating pressure for version with linear valve max. 150 bar).
This Quick Connector has been designed for gas cylinder valves acc. to DIN 477 and is available on request also for other connection possibilities, i.e. BS, NF, CGA etc.
- Suitable for filling of CO₂ or refrigerants
- Connection in seconds
- 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® Jaw Locking Mechanism
- High-grade materials
