Viega 90526 – Frequently Asked Questions
1) What does the Viega 90526 PureFlow press adapter connect to on each end?
The 90526 is a press-by-male-thread adapter: one end is a PureFlow press socket, the other is a 3/4 inch male pipe thread. It's the transition you use to take a PEX press run onto a threaded female port, like a valve, manifold tapping, or appliance connection. Sizes are 1/2 inch by 3/4 inch, so the press side is the 1/2 inch and the thread side the 3/4 inch NPT.
2) Is the Viega 90526 adapter safe for potable drinking water?
Yes. It's a zero lead bronze body, which is the alloy Viega uses for potable water service on the PureFlow line. Bronze also gives it more thread strength than a polymer adapter when you're torquing into a valve or a female iron port.
3) Can I use the 90526 to run 1/2 inch PEX to a 3/4 inch threaded valve or stub-out?
That's exactly what it's for. The 1/2 inch press socket takes the PEX, and the 3/4 inch male thread goes into any 3/4 inch female NPT port. You're reducing the flow to 1/2 inch at that point, so if the fixture or appliance genuinely needs full 3/4 inch flow, run 3/4 inch PEX with a 3/4 by 3/4 adapter instead.
4) Does the Viega 90526 press adapter need a special press tool and jaw?
It presses with a PureFlow press tool and the 1/2 inch jaw or ring, matched to the 1/2 inch press end. The 3/4 inch side is threaded, so that connection is made with a wrench and thread sealant, not the tool. Order the jaw by the press size, not by the 3/4 inch thread size, which is the most common mistake on a reducing adapter like this.
5) How much room does the Viega 90526 adapter take up in a tight wall cavity?
It's a compact fitting: 1.642 inches wide, 1.142 inches high, 1.063 inches long, and 0.152 pounds. That matters when you're pressing inside a 2x4 stud bay or behind a fixture escutcheon, because you need clearance for the jaw around the press socket, not just for the fitting body.
6) Should I use a bronze press adapter or a poly one for a 3/4 inch threaded connection?
Bronze is the choice where the threaded joint sees wrench torque, repeated service disconnects, or a heavier valve hanging off it, and it's the one to spec when a job calls for a metallic potable fitting. The 90526's zero lead bronze body handles that. Polymer adapters are lighter and cheaper, but a 3/4 inch male thread in poly is easier to over-torque and crack during install.
