Viega 91850 – Frequently Asked Questions
1) Does the Viega 91850 MegaPress tee have a threaded outlet?
Yes. The 91850 MegaPress tee is configured P1 x P2 x FPT, so two ends are press connections and the branch is a female pipe thread. That lets you press into the run and thread a gauge, drain, valve nipple or sensor into the branch without any further adapter.
2) What pipe size does the Viega 91850 MegaPress tee fit?
It is a 3/4 inch x 3/4 inch x 3/4 inch tee, so both press ends take 3/4 inch pipe and the branch is a 3/4 inch female thread. Overall it measures 4.575 inches long, 2.327 inches wide and 1.496 inches high, which matters when you are fitting it into a tight joist bay or ganged pipe rack.
3) Is the Viega 91850 press tee stainless or carbon steel?
316 stainless steel. That is the corrosion-resistant grade, so it suits stainless pipe runs and wet or chemically aggressive environments rather than the carbon steel MegaPress fittings used on black iron gas and hydronic lines. Don't substitute it into a carbon steel run expecting a matching fitting body, the material grades are different products.
4) What does Smart Connect technology on the Viega 91850 tee actually do for the installer?
Smart Connect is Viega's unpressed-connection feature: an unpressed joint leaks intentionally during pressure testing so you can find it before the system is charged and closed in. On a 3/4 inch MegaPress tee with two press ends, that means a crew pressing dozens of joints can test the run and spot a missed press instead of chasing it after drywall.
5) Should I use a press tee like the Viega 91850 or a threaded or welded tee on stainless pipe?
A press tee is the choice when you want a cold, flame-free joint on existing stainless pipe, which is what gets you into occupied buildings, hospitals and kitchens without a hot work permit. A welded tee needs a certified welder and burn protection, and a fully threaded tee needs the pipe cut, reamed and threaded on site. The 91850 splits the difference: pressed on the two run ends, with an FPT branch so you still have a threaded take-off where you need one.
6) Can I press the Viega 91850 with my existing press tool jaws?
MegaPress stainless fittings press with MegaPress jaws or rings sized for the pipe, and this tee uses 3/4 inch press ends on both run connections. Match the jaw to the MegaPress profile and the 3/4 inch size; standard copper press jaws are a different profile and are not interchangeable.
7) What is the exact part number to order the Viega 3/4 inch stainless MegaPress tee with a threaded branch?
Viega part number 91850. That gets you the 316 stainless MegaPress tee, 3/4 inch x 3/4 inch x 3/4 inch, with two press ends and an FPT branch. It is a single model, so there are no finish or size options to specify.
8) Where is the Viega 91850 MegaPress tee made?
Made in Germany. For spec packages and government or institutional submittals that require country of origin on each line item, that is the value to enter for the 91850.
