Viega 25621 – Frequently Asked Questions
1) What kind of connection does the Viega MegaPressG 25621 adapter have on each end?
The 25621 is a P x FPT adapter: one press end and one female pipe thread end. That lets you transition from a pressed carbon steel run to a male-threaded component such as a valve, union or appliance connector without cutting a thread on site.
2) Is the Viega 25621 a 1-1/2 inch or 1-1/4 inch fitting?
Both, in one part. The 25621 is sized 1-1/2 inch by 1-1/4 inch, so it presses onto 1-1/2 inch carbon steel pipe and reduces to a 1-1/4 inch female threaded outlet. If you need the same size on both ends, this is not the part.
3) Can I use a MegaPressG carbon steel press adapter on copper or stainless pipe?
No. The 25621 is a carbon steel MegaPressG fitting, so its press end is made for black/carbon steel pipe. Copper and PEX take Viega ProPress and PureFlow systems instead, and stainless runs take a stainless press fitting. Matching the fitting material to the pipe material is not optional on a press system.
4) Is the Viega 25621 the gas version or the water version?
It is MegaPressG, Viega's carbon steel press line for gas, with Smart Connect technology in the fitting. Plain MegaPress is the non-gas carbon steel line. If a submittal calls for MegaPressG, specify by model number 25621 so the gas-rated version is what arrives.
5) Does the MegaPressG 25621 adapter need a special press tool jaw?
It presses with a press tool and a jaw or ring sized for the press end, which on the 25621 is 1-1/2 inch carbon steel. The threaded side is 1-1/4 inch FPT and takes a wrench, not the tool. Confirm your press tool is rated for 1-1/2 inch MegaPress carbon steel before you get to the riser.
6) How much room do I need around the Viega 25621 adapter in a tight chase?
The fitting measures 3.413 inches long, 2.437 inches high and 2.437 inches wide, and weighs 0.849 lbs. You also need clearance for the press jaw to close fully around the press end, which is usually the limiting factor in a chase rather than the fitting body itself.
7) What does Smart Connect do on a Viega press fitting?
Smart Connect is a feature of the sealing element that lets an unpressed connection leak intentionally during pressure testing, so a joint you missed shows itself before the wall closes up. The 25621 carbon steel MegaPressG adapter includes it.
8) Where is the Viega 25621 MegaPressG adapter made?
Made in Germany. That matters on institutional and government jobs where country of origin has to be documented on the submittal.
