Viega 25045 – Frequently Asked Questions
1) What size pipe does the Viega MegaPress 25045 coupling join?
The 25045 is a 1-1/4 inch by 1-1/4 inch MegaPress coupling, so it joins two runs of 1-1/4 inch carbon steel pipe. Both ends are press connections (P1 x P2), not threaded and not grooved.
2) What does "no stop" mean on the Viega 25045 MegaPress coupling?
No stop means there is no internal shoulder inside the coupling, so pipe can slide all the way through. That is what you want for a repair: cut out the damaged section, slide the coupling fully onto one pipe end, bring the new piece in, then slide it back to center and press both ends. A stop-type coupling can't do that because the pipe bottoms out halfway.
3) Can I use the 25045 MegaPress coupling on black iron gas pipe, or is it for water only?
The 25045 is a carbon steel MegaPress press fitting for carbon steel pipe systems. Which service it is approved for depends on the sealing element in the fitting, so confirm the MegaPress series (standard versus MegaPressG for gas) matches the application before you press it in.
4) What is Smart Connect on Viega MegaPress fittings?
Smart Connect is Viega's unpressed-connection feature. If a fitting gets missed during pressing, it leaks visibly at low test pressure during pressure testing, so you find the joint before the walls close up instead of after. The 25045 coupling includes it.
5) How much room do I need around the pipe to press a 1-1/4 inch MegaPress coupling?
The fitting body itself is 2.205 inches across and 4.311 inches long, so plan clearance for that plus the press tool jaw swing around the pipe. In tight ceiling or wall cavities, that jaw clearance, not the fitting, is usually what decides whether you can press in place.
6) Where is the Viega 25045 MegaPress fitting made, and what is its part number?
Part number 25045, made in Germany by Viega. It weighs 0.86 lbs, which matters if you're pricing out a bulk pallet of fittings for a mechanical room job.
