Viega 91615 – Frequently Asked Questions
1) Is the Viega 91615 MegaPress tee an equal 1-1/2 inch tee on all three ports?
Yes, all three outlets on the Viega 91615 MegaPress tee are 1-1/2 inch, so it branches a 1-1/2 inch run without a reducer. The port configuration is press x press x press (P1 x P2 x P3), meaning every connection is made with a press tool, not threaded or welded.
2) What material is the Viega 91615 MegaPress tee, and will it hold up in a corrosive mechanical room?
It is 316 stainless steel, the molybdenum-bearing grade used where chlorides and washdown chemicals attack 304. That makes the 91615 tee suited to industrial and coastal mechanical rooms where a carbon steel press fitting would pit.
3) Can I use the Viega 91615 MegaPress tee on carbon steel pipe, or does it need stainless pipe?
MegaPress fittings press onto IPS black iron and carbon steel pipe; the 91615 is the 316 stainless version of the fitting body, chosen for the corrosion resistance of the fitting itself. Confirm your pipe is 1-1/2 inch IPS schedule pipe in good condition at the press location, since the seal is made on the pipe OD.
4) What is Smart Connect on the Viega 91615 tee and why does it matter on a big job?
Smart Connect is the feature that lets an unpressed connection leak visibly during pressure test, so a missed joint shows up before the system is charged and closed in. On a run with dozens of 1-1/2 inch presses, that is what keeps you from chasing a single skipped fitting behind drywall.
5) How much space do I need to fit the Viega 91615 MegaPress tee in a tight chase?
The 91615 tee measures 6.953 inches by 4.65 inches by 2.437 inches overall. Allow clearance beyond that for the press tool jaw to seat squarely around each of the three 1-1/2 inch ports, which is usually the limiting factor rather than the fitting body.
6) Do I need to thread or weld anything to install the Viega 91615 tee?
No cutting oil, no threading, no hot work. All three 1-1/2 inch ports are press connections, so installation is cut, deburr, mark depth, and press with a compatible press tool and jaw. That is the usual reason it gets specified in occupied buildings where a hot work permit is a problem.
7) What is the exact part number and origin for the Viega 1-1/2 inch stainless MegaPress tee?
Order it as Viega part 91615. It is made in Germany, which is the detail most often asked for on specs and submittals that call out country of origin.
8) How heavy is a 1-1/2 inch MegaPress stainless tee for overhead hanger spacing?
The 91615 tee weighs 1.882 lbs on its own. Add that to the filled pipe weight when you set hanger locations near the branch, since press tees are typically supported on the adjacent run rather than at the fitting.
