Viega 25666 – Frequently Asked Questions
1) What connection ends does the Viega 25666 MegaPressG fitting have?
It's a P x FPT fitting: one press end and one female pipe thread end, both 1-1/4 inch. So it presses onto 1-1/4 inch carbon steel pipe on one side and threads onto a 1-1/4 inch male NPT nipple, valve, or appliance connector on the other. Use it where you need to transition out of a pressed run into threaded equipment without cutting threads on the pipe.
2) Can I use the Viega 25666 on copper or stainless tubing?
No. The 25666 is a carbon steel MegaPressG fitting and its press end is sized for 1-1/4 inch carbon steel pipe. Copper tube needs a copper press fitting (ProPress), and stainless needs a stainless press fitting. Mixing the press end with the wrong pipe material and wall gives you a joint the jaw will not seal correctly.
3) What is Smart Connect on this Viega MegaPressG fitting and why does it matter on a gas line?
Smart Connect is the feature built into the sealing element that intentionally leaks at an unpressed connection during pressure test, so a joint you skipped shows itself before the system goes into service. On a gas installation that is the difference between finding a missed press at test and finding it after the wall is closed. It is part of the fitting itself on the 25666, nothing to order separately.
4) I'm standardizing a building's gas piping on press. Does the 25666 let me tie into existing threaded pipe?
That's exactly what the female threaded end is for. Where an existing black iron run ends in a male thread, or where you're landing on a shutoff valve, regulator, or appliance connector with male NPT, the 25666 threads onto it and gives you a 1-1/4 inch press end to carry the new work forward. It keeps the tie-in points threaded and everything downstream pressed.
5) What's the exact part number and where is the Viega 25666 made?
Order it as Viega part number 25666, the 1-1/4 inch x 1-1/4 inch MegaPressG carbon steel fitting with a press end and a female threaded end. It is made in Germany.
