Viega 91225 – Frequently Asked Questions
1) What kind of connection does the Viega MegaPress 91225 adapter have on each end?
The 91225 is a press by male pipe thread adapter (P x MPT) in 1-1/4 inch by 1-1/4 inch. One end presses onto 1-1/4 inch pipe with a MegaPress tool and jaw; the other is a 1-1/4 inch male NPT thread you screw into a female fitting, valve, or threaded equipment connection. No solder, no cutting threads in the field.
2) Is the Viega 91225 MegaPress adapter stainless or carbon steel?
It's 316 stainless steel, not carbon steel. That matters when you are picking a press fitting for a line where corrosion is a concern, since the standard MegaPress body is carbon steel for black iron pipe. 316 is the higher molybdenum-bearing grade used where chlorides or wash-down conditions attack lesser alloys.
3) How much room do I need to press a 1-1/4 inch MegaPress stainless adapter in a tight chase?
The fitting body itself is 3.705 inches long and 2.205 inches across in both height and width. Add clearance beyond that for the press tool jaw to seat square on the press ring, so a chase or joist bay that only just clears the 2.205 inch body will not let you make the joint.
4) Does the Viega 91225 have Smart Connect, and what does that actually do for me on an inspection?
Yes, the 91225 is a Smart Connect fitting. The feature deliberately leaks a small amount during pressure testing if the joint has not been pressed, so an unpressed connection shows itself on test rather than after the wall is closed. On a multi-fitting riser that is the fastest way to find the one joint the crew missed.
5) Can I thread the male end of this MegaPress adapter straight into a 1-1/4 inch FIP valve or gauge port?
Yes. The threaded end is 1-1/4 inch male pipe thread, so it mates with any 1-1/4 inch female NPT port, union, or valve. Use thread sealant or PTFE tape on the taper as you would with any NPT joint; the press end handles the pipe side and needs no sealant at all.
6) I need to branch a line in three directions, not transition to thread. Is the 91225 the right fitting?
No. The 91225 is a two-end adapter, press on one side and male thread on the other. It transitions, it does not branch. For a three-way branch you need a MegaPress tee in the matching 316 stainless family rather than this adapter.
