Viega 26640 – Frequently Asked Questions
1) What are the two ends on the Viega MegaPress 26640 adapter, press or threaded?
One end is a 2-1/2 inch MegaPress press connection and the other is a 2-1/2 inch male pipe thread (P x MPT). So it presses onto 2-1/2 inch carbon steel pipe on one side and threads into a female NPT fitting, valve, or union on the other. Use it where you are transitioning a pressed carbon steel run into existing threaded equipment.
2) Will the Viega 26640 MegaPress adapter work on black iron gas or hydronic pipe?
It is a carbon steel fitting sized for 2-1/2 inch pipe, which is the same material family as black iron schedule pipe used on gas and hydronic steel systems. Matching carbon steel to carbon steel avoids the dissimilar metal issue you would create pressing a copper or bronze fitting onto a steel line. Confirm the system pressure and media against Viega's approvals for your application.
3) Do I need to thread or weld 2-1/2 inch steel pipe to install this Viega adapter?
No cutting oil, no threading machine, and no torch on the press side. The MegaPress end is made with a press tool and jaw sized for 2-1/2 inch, so the only threading involved is on the MPT end, which screws into existing female NPT. That is what makes it useful for occupied buildings and hot work permit situations.
4) What does Smart Connect do on a Viega MegaPress fitting?
Smart Connect is Viega's unpressed-connection feature: an unpressed fitting leaks visibly during pressure testing, so it gets caught on the test rather than inside a wall. On a 2-1/2 inch carbon steel run with many joints, that is the practical safeguard an inspector and a GC care about.
5) How heavy is the 2-1/2 inch Viega MegaPress adapter for overhead support spacing?
It weighs 1.895 lbs. Light enough that a single 2-1/2 inch hanger near the joint handles it, but with a threaded takeoff hanging off the MPT end you should still support the connected equipment independently rather than letting it load the fitting.
6) Where is the Viega 26640 MegaPress adapter made?
Made in Germany. For public and institutional work with country-of-origin reporting on the submittal, that is the value to put on the form for this carbon steel fitting.
