Viega 25591 – Frequently Asked Questions
1) What kind of connections does the Viega MegaPressG 25591 adapter have?
It is a P x FPT adapter: one press end and one female pipe thread end. The press side goes onto the pipe with a press tool jaw, and the FPT side takes a male threaded fitting or nipple. Sizes are 1-1/4 inch by 1/2 inch.
2) Is the Viega 25591 MegaPressG fitting for gas lines or for water?
MegaPressG is Viega's carbon steel press system for gas piping, and the 25591 is a MegaPressG carbon steel adapter. For water or hydronic service on black iron, the plain MegaPress line is the one to order instead; the G suffix is what identifies the gas-rated sealing element.
3) What pipe does the press end of the Viega 25591 go on?
The press end is sized 1-1/4 inch and the fitting body is carbon steel, so it presses onto 1-1/4 inch black iron pipe. Carbon steel press fittings are not for copper or stainless tube; those take the copper or stainless press systems.
4) Can I use the Viega 25591 to drop a 1/2 inch threaded branch off a 1-1/4 inch gas main?
Yes, that is exactly what it does. The 1-1/4 inch press end joins the main and the 1/2 inch FPT outlet takes a threaded nipple, valve, or appliance connector. Thread that joint with an approved gas-rated sealant; the press end needs no sealant.
5) What does Smart Connect do on the Viega 25591 adapter?
Smart Connect is the feature that lets an unpressed connection leak visibly during pressure testing, so the installer can find a joint that was missed before the system is charged. It is built into the 25591 MegaPressG adapter, which matters most on gas runs with a lot of joints.
6) What is the Viega part number and where is it made?
Order it as Viega MegaPressG 25591. It is made in Germany.
