Viega 25351 – Frequently Asked Questions
1) What pipe sizes does the Viega MegaPressG 25351 tee connect?
The MegaPressG tee, model 25351, is a reducing tee sized 1-1/4 inch x 1-1/4 inch x 1 inch. The run is 1-1/4 inch on both ends and the branch outlet is 1 inch, so you can take a 1 inch branch off a 1-1/4 inch main without adding a separate reducer. All three ends are press connections (P1 x P2 x P3), not threaded.
2) Will the Viega 25351 press tee work on black iron / carbon steel gas pipe?
Yes. The 25351 is a carbon steel MegaPressG fitting, so it is made to press onto carbon steel pipe rather than copper or stainless. Keeping the fitting material the same as the pipe material avoids dissimilar-metal issues in the joint.
3) Do I need to thread pipe to install the Viega MegaPressG 25351 tee?
No threading, no cutting oil, no flame. All three outlets on the 25351 are press connections, so the joint is made with a press tool and the matching jaw or ring for the size. You cut the pipe square, deburr, mark insertion depth, and press. On a 1-1/4 x 1-1/4 x 1 tee that means two 1-1/4 inch presses and one 1 inch press.
4) How much clearance do I need around a 1-1/4 inch MegaPressG tee in a tight chase?
The fitting body measures 6.457 inches long, 3.831 inches wide and 2.205 inches high, and it weighs 1.477 lbs. Those are the fitting dimensions only, so add the swing room your press tool jaw needs on each of the three outlets before you commit to a tight chase or a joist bay.
5) Is the Viega 25351 tee the same as a MegaPress tee for water?
They are different product lines. The 25351 is a MegaPressG tee, the gas version of Viega's carbon steel press system, identified by model 25351 on the fitting. MegaPress and MegaPressG fittings look similar and share the carbon steel body, so check the model number and the line marking before you press it in, since the sealing element differs by application.
6) What exact part number should I order for a Viega 1-1/4 x 1-1/4 x 1 MegaPressG tee?
Order Viega 25351. That is the manufacturer part number for the carbon steel MegaPressG reducing tee at 1-1/4 inch x 1-1/4 inch x 1 inch, UPC 691514253510. It is made in Germany.
7) Does the Viega MegaPressG 25351 tee include anything to tell me the joint was pressed?
It carries Viega's Smart Connect feature, the design that leaks visibly at an unpressed connection during pressure testing so an unpressed joint shows itself before the system is put in service. That matters on a three-outlet fitting like this one, where it is easy to miss the branch press.
