Viega 25700 – Frequently Asked Questions
1) Will the Viega 25700 MegaPress fitting work on 1/2 inch carbon steel pipe?
Yes. The 25700 is a carbon steel MegaPress fitting sized 1/2" x 1/2", with a press connection on each end (P1 x P2). MegaPress is the carbon steel line, so it presses onto 1/2 inch carbon steel pipe, commonly called black iron or black steel in the field. It is not a copper-tube fitting, and it will not press onto copper.
2) Do I have to thread or weld the Viega 25700 MegaPress fitting?
No cutting oil, no dies, no torch. Both connections on the 25700 are press (P1 x P2), so the pipe is cut, deburred, marked to depth and pressed with a press tool and the matching carbon steel jaw. That is the reason crews use MegaPress in occupied buildings, mechanical rooms and anywhere a hot work permit is a problem.
3) Can I use a Viega MegaPress carbon steel fitting on a domestic water line?
Carbon steel is the wrong material for potable water. The 25700 is a carbon steel body, which is what MegaPress is built for: black steel systems such as hydronic heating, chilled water, compressed air, and fire protection piping. For potable copper or PEX work, use the copper or PEX press line rather than a carbon steel fitting.
4) What is Smart Connect on the Viega 25700, and why does it matter on a pressure test?
Smart Connect is Viega's unpressed-connection feature. On a fitting that has been slipped on but not pressed, it lets test fluid or air escape past the seal during the pressure test, so the missed joint shows itself before the wall closes up. On a repipe with dozens of 1/2 inch connections, that is the difference between finding the miss on test day and finding it after drywall.
5) How much room does the Viega 25700 need in a tight joist bay or wall cavity?
The 25700 measures 4.496" long, 1.772" wide and 1.614" high, and weighs 0.76 lbs. Lay that out against your cavity before you cut, and remember the press jaw itself needs clearance around the fitting collar, not just the fitting footprint.
6) What part number do I put on a Viega MegaPress 1/2 inch carbon steel submittal?
Order it as Viega MegaPress 25700, manufacturer part number 25700, carbon steel, 1/2" x 1/2", press by press. It is made in Germany. That is the full identity a spec reviewer or purchasing agent needs to match it.
