Viega 46622 – Frequently Asked Questions
1) What does the Viega 46622 PureFlow adapter connect to on each end?
The Viega 46622 is a crimp-to-copper adapter: one end is a 3/8 inch PureFlow crimp connection for PEX, and the other is a copper sweat end listed as C or FTG, meaning it works as a 3/8 inch copper cup or a 1/2 inch fitting-end that slips into a 3/8 inch copper socket. That is what the "3/8 x 3/8 or 1/2" size call-out means. Use it where a PEX branch has to tie into existing copper tube.
2) Is the Viega 46622 PEX adapter safe for potable drinking water lines?
It is a zero lead brass fitting, so it is intended for potable water distribution. Both the material fields list brass, and the product name specifies Zero Lead Brass. It is also made in the USA.
3) Can I use the Viega 46622 with Viega PEX Press or ProPress tools?
No. The 46622 is a PureFlow crimp fitting, which uses a copper crimp ring set with a crimp tool and go/no-go gauge. Press-fit systems use a different fitting body with a sealing element and a press jaw. If your installation standard is press, order a press-style PEX-to-copper adapter instead of this one.
4) Do I solder or crimp the Viega 46622 adapter, and in what order?
Both. The copper end is a sweat joint and the PEX end is a crimp ring connection. Solder the copper side first, with the PEX tubing and crimp ring off the fitting, then let the brass cool before crimping the PureFlow side. Heating the fitting with PEX already attached will damage the tubing and the ring seal.
5) Will the Viega 46622 fit in a tight wall cavity or behind a fixture?
It is a compact fitting: 1.33 inches on the height dimension and 0.626 inches on both length and width, weighing 0.036 lbs. That leaves room in shallow stud bays and behind lavatory or toilet supply drops, though you still need clearance around the copper end for a torch.
