Viega 43343 – Frequently Asked Questions
1) Does the Viega 43343 PureFlow coupling reduce from 3/4 inch to 1/2 inch PEX?
Yes. The Viega 43343 is a reducing coupling sized 3/4 inch by 1/2 inch, so it joins a 3/4 inch PEX run to a 1/2 inch branch or fixture drop without needing a separate reducer bushing. Both ends are crimp connections.
2) Is the Viega 43343 coupling metal or plastic?
It is PolyAlloy, Viega's engineered polymer. That makes it a non-metallic option for water systems where installers want to avoid brass, and it is the usual choice on jobs where dezincification of brass fittings is a concern. If your spec calls out a metallic fitting body, this is not the part.
3) Is the Viega PureFlow 43343 coupling made in the USA for domestic-preference jobs?
Yes, the 43343 PolyAlloy reducing coupling is made in the USA, which is what institutional and government procurement typically needs documented on the submittal.
4) What part number do I order for a Viega PureFlow 3/4 x 1/2 PolyAlloy crimp coupling?
Order Viega 43343. That is the manufacturer part number for the PureFlow PolyAlloy crimp coupling in the 3/4 inch by 1/2 inch reducing size, and it is a single configuration with no finish or option choices to specify.
5) Can I use the Viega 43343 coupling to join PEX to copper pipe?
No. Both ends of the 43343 are crimp sockets for PEX tubing, sized 3/4 inch and 1/2 inch. To transition to copper you need a PEX-to-copper adapter or a threaded adapter plus a sweat fitting, not this coupling.
6) How much room does the Viega 43343 PureFlow coupling take up in a wall cavity?
It is small. The body measures 1.5 inches long and 0.728 inches across, so with a crimp ring on each end it fits inside a standard stud bay or a tight manifold cluster. Weight is negligible at 0.01 lbs, so it needs no support of its own beyond normal PEX hanging.
