Viega 28845 – Frequently Asked Questions
1) What size pipe does the Viega 28845 MegaPressG reducer connect?
The Viega 28845 MegaPressG carbon steel reducer is a 4 inch by 2 inch fitting, so it steps a 4 inch run down to a 2 inch outlet. Overall length is 7.268 inches, with height and width both at 4.5 inches, which is worth checking against your available space in a tight chase or against adjacent hangers.
2) Is the Viega 28845 MegaPressG fitting suitable for black iron gas pipe?
Yes. The 28845 is carbon steel and part of the MegaPressG line, which is Viega's press system for gas piping on carbon steel pipe. Matching carbon steel fitting to carbon steel pipe is what keeps the joint metallurgically consistent on a gas run.
3) What is Smart Connect on the Viega 28845, and why does it matter during pressure test?
Smart Connect is the feature built into the MegaPressG sealing element that deliberately leaks at an unpressed connection during test, so an installer can find a missed joint before the system is charged. On a gas branch reduction like this 4 inch by 2 inch fitting, that is the difference between catching a miss at test and chasing it after the wall closes.
4) Should I use a press reducer like this or thread and weld the 4 inch to 2 inch transition?
A press reducer removes the hot work and the threading from the transition, which is why it gets specified in occupied buildings, mechanical rooms and retrofits where a torch permit is a problem. The tradeoff is tooling: a pressed joint needs the correct press tool and jaw or ring for the size, and at 4 inch that is large-diameter tooling, not a standard compact tool. If the crew already owns threading or welding gear and the work area allows hot work, threaded or welded is the lower equipment hurdle.
5) Is Viega 28845 a tee or a straight reducer?
Part 28845 is catalogued by Viega as a reducer and carries FTG x P ends, meaning two connections in line rather than a branch outlet. If you need a 2 inch branch taken off a 4 inch main, you want a reducing tee, not this part.
6) Where is the Viega 28845 MegaPressG fitting made?
Made in Germany. For spec packages and submittals that call for country of origin on gas piping components, that is the value to list against part 28845.
