Viega 91655 – Frequently Asked Questions
1) What size pipe does the Viega 91655 MegaPress tee fit?
The 91655 MegaPress tee is a reducing tee sized 1-1/4 inch x 1-1/4 inch x 1 inch. The run is 1-1/4 inch on both ends and the branch outlet is 1 inch, so it drops a 1 inch takeoff out of a 1-1/4 inch line without needing a separate bushing or reducer at the branch.
2) Are all three ends of the Viega 91655 tee press connections?
Yes. The connection configuration is P1 x P2 x P3, meaning all three outlets are press ends. There is no threaded or sweat port on this fitting, so the 1 inch branch has to be picked up with press or with a press-to-thread adapter downstream.
3) Is the Viega 91655 MegaPress tee carbon steel or stainless?
It is 316 stainless steel, not the carbon steel body used on standard MegaPress. The 316 alloy adds molybdenum, which is why this version gets specified where the line or the surrounding environment is corrosive, such as chemical service, wash-down areas, or coastal and industrial plants.
4) What does Smart Connect on the Viega 91655 tee actually do for the installer?
Smart Connect is Viega's unpressed-connection feature: an unpressed fitting leaks visibly during pressure test rather than holding temporarily and failing later. On a three-outlet fitting like this 1-1/4 x 1-1/4 x 1 tee that matters, because you have three separate presses to make and one missed branch is easy to overlook on a long run.
5) How much clearance do I need to install the 1-1/4 inch MegaPress stainless tee in a tight chase?
The fitting itself measures 6.535 inches long, 3.831 inches wide and 2.205 inches high. Lay that out before committing to a chase or a joist bay, and remember the press tool jaw needs room around each of the three ends on top of the fitting body.
6) Should I use a stainless MegaPress tee or the standard carbon steel one on a black iron line?
Pick by the service, not the existing pipe. The 91655 is 316 stainless, which is what you want when the medium or the environment will attack carbon steel. For ordinary dry sprinkler, gas or hydronic black pipe with no corrosion concern, the carbon steel MegaPress equivalent is the normal choice. Both are press systems for iron pipe size; the difference is alloy.
7) What is the part number and manufacturer for the 1-1/4 x 1-1/4 x 1 MegaPress stainless tee?
Manufacturer is Viega and the part number is 91655. It is made in Germany. Quote it by that number; the stainless and carbon steel MegaPress tees share nominal sizes, so the part number is the only reliable way to be sure you get the 316 stainless body.
8) How heavy is the Viega 91655 tee for overhead support spacing?
It weighs 1.448 lbs. Light enough that a single 1-1/4 inch line hanger either side of the branch handles it, but account for the 1 inch takeoff being supported separately rather than hanging off the fitting.
