Viega 91930 – Frequently Asked Questions
1) What size pipe does the Viega 91930 MegaPress union fit?
The Viega 91930 MegaPress union is a 3/4 inch by 3/4 inch fitting, with press ends on both sides (P1 x P2). It joins two runs of 3/4 inch pipe, so both ends must be the same nominal size.
2) Is the Viega 91930 MegaPress union stainless steel or carbon steel?
It is 316 stainless steel throughout. That is the corrosion-resistant grade, so it suits applications where plain carbon steel MegaPress would be the wrong call, such as wet or chemically aggressive environments. The fitting is made in Germany.
3) Does the 3/4 inch MegaPress stainless union need thread or weld prep?
No. Both ends are press connections, not threaded or welded, so the joint is made cold with a press tool and jaw sized for 3/4 inch MegaPress. No pipe threading, no flame, no field welding. You do still need the correct press tool and jaw set, which is not part of the fitting.
4) What does Smart Connect technology do on the Viega 91930 union?
Smart Connect is Viega's feature that leaves an unpressed connection deliberately leaky during pressure testing, so an installer can spot a joint that was missed before the system is put into service. On a union it matters twice over, since there are two separate press ends to make up.
5) How much space do I need to fit the 91930 MegaPress union in a tight chase?
Plan on roughly 4.984 inches of length, 2.028 inches of width and 1.811 inches of height for the fitting itself. Add clearance beyond that for the press jaw to close around each end, which is usually the real constraint in a chase or against a joist.
6) Can I use a MegaPress union to break into an existing 3/4 inch line later for service?
A union gives you a disconnect point in a run, which is what makes it the fitting to use where a pump, valve or section of pipe may need to come out later. Both sides press onto 3/4 inch pipe, so you set it once and the union itself becomes the service break instead of cutting the pipe again.
7) How heavy is a single Viega 91930 stainless union for estimating a hanger layout?
Each one weighs 1.045 lbs. That is the fitting alone, so when you are supporting a run with several unions in it, add the fitting weight plus the water-filled pipe load when spacing hangers.
