Please select variant!

The WEH® TW640 Manual connector has been specially developed for pallet filling of gas cylinders with female threads. The TW640 is simply placed into the cylinder valve and tightened by hand until the o-ring seal contacts the counterpart. Now the pressure-tight connection is made.
Thanks to the pressure support, the manual connector seals without wrenches, sealants or tape, thus saving connection times and costs.
