Viega 25710 – Frequently Asked Questions
1) Will the Viega MegaPress 25710 work on 1 inch black iron pipe?
The 25710 is a 1 inch x 1 inch MegaPress fitting in carbon steel, so it presses onto 1 inch carbon steel (black iron) pipe. Both ends are press connections (P1 x P2), meaning no threading, no cutting oil, and no torch on either side. Carbon steel MegaPress is the carbon steel pipe system, not the copper one, so don't put this on copper tube.
2) Do I need to thread or weld anything to install the Viega 25710?
No threading and no welding. Both ends of the 25710 are press ends (P1 x P2), so the joint is made with a press tool and the correct 1 inch jaw. That is the whole point of MegaPress on carbon steel pipe: cut the pipe square, deburr, mark the insertion depth, and press. You do still need a press tool and jaws sized for 1 inch, which are separate from the fitting.
3) Can I use a MegaPress fitting to break into an existing threaded carbon steel line?
Not on its own. The 25710 has press ends on both sides (P1 x P2), so it mates to plain-end carbon steel pipe, not to threads. To tie into an existing threaded line you need a press-by-thread adapter at the transition, then this fitting downstream on the plain pipe.
4) What does Smart Connect on a Viega MegaPress fitting actually do for me?
Smart Connect is the feature that shows you an unpressed connection during pressure testing: liquid or gas escapes past the sealing element at an unpressed joint so you can find it before the system is buttoned up. On a 1 inch carbon steel run with a lot of joints, that is what keeps you from chasing a missed press behind a ceiling later.
5) How much room does the Viega 25710 take up in a tight ceiling or chase?
Plan on a fitting roughly 5.339 inches by 2.362 inches by 2.165 inches, weighing 1.406 lbs. Beyond the fitting body itself you also need swing clearance for the press jaw around the 1 inch pipe, which is usually the real constraint in a chase rather than the fitting envelope.
6) Is the Viega 25710 the right part number to spec, and where is it made?
The manufacturer part number is 25710, a Viega MegaPress carbon steel fitting at 1 inch x 1 inch, made in Germany. For a submittal or a standardization list, 25710 is the number to carry; the size and material are what separate it from the adjacent MegaPress models, so confirm you want carbon steel at 1 inch rather than another size in the same family.
