Viega 28840 – Frequently Asked Questions
1) What size pipe does the Viega 28840 MegaPressG reducer fit?
The Viega 28840 MegaPressG reducing fitting is sized 4 inch x 1-1/2 inch, so it transitions a 4 inch run down to a 1-1/2 inch branch or outlet. Both ends are built for black iron (carbon steel) pipe of those nominal sizes.
2) Can I use the Viega MegaPressG 28840 on a gas line?
MegaPressG is Viega's gas-rated press line, and the 28840 is a MegaPressG carbon steel fitting, so it is intended for gas piping on black iron pipe rather than the water-only MegaPress sealing element. Press it with the same Viega press tool and jaw set used for the size you are joining.
3) Is the Viega 28840 fitting copper or steel, and will it work on my black iron pipe?
It is carbon steel, which is what you want on black iron pipe. Carbon steel press fittings go on carbon steel pipe; do not use this on copper or stainless lines, which take Viega's copper-press or stainless press fittings instead.
4) What is the Smart Connect feature on Viega MegaPressG fittings for?
Smart Connect is a deliberate leak path designed into the sealing element so an unpressed connection shows itself during pressure testing instead of passing inspection and failing later. On a gas line with a 4 inch x 1-1/2 inch reducer buried in a chase, that is the difference between catching a missed press at test and finding it after the wall closes.
5) Do I need any extra sealant or dope on a MegaPressG 28840 connection?
No. The seal is made by the factory-installed sealing element inside the press socket when the fitting is crimped, so there is no thread sealant, flux, or solder involved. What you do need is a correctly cut and deburred pipe end, the pipe marked to full insertion depth, and the matching Viega jaw or ring for the size being pressed.
