Viega 98430 – Frequently Asked Questions
1) What connections does the Viega MegaPress 98430 tee have on each port?
The 98430 is a reducing tee with two press ends and one female threaded branch: P1 x P2 x FPT. The two 4 inch runs are press connections made with a MegaPress tool and jaw, and the 3/4 inch branch is female pipe thread, so you can thread in a gauge, sensor, drain valve, or a nipple without any press tooling on that port.
2) Can I press the Viega 98430 onto 4 inch black iron or carbon steel pipe, or does it need stainless pipe?
MegaPress fittings press onto IPS black, galvanized, and carbon steel pipe as well as stainless; the 316 stainless version like the 98430 is the one chosen when the system piping or the environment calls for stainless. The press ends are sized for 4 inch IPS pipe, not tube, so confirm your run is nominal 4 inch iron pipe size before ordering.
3) I need a 4 inch branch off my main, not 3/4 inch. Is the Viega 98430 the right tee?
No. The 98430 reduces hard: the run is 4 inch x 4 inch and the branch is only a 3/4 inch female thread. It's for tapping a small takeoff, instrument, or drain off a 4 inch main. For a full-size branch you need a different MegaPress tee with the branch sized to your pipe.
4) Is the Viega 98430 MegaPress tee suitable for a corrosive or washdown environment?
The body is 316 stainless steel, which is the grade specified where chloride exposure or washdown chemicals would attack carbon steel or 304. That makes it a fit for food and beverage plants, coastal mechanical rooms, and chemical process lines. It's made in Germany.
5) What does Smart Connect on the Viega 98430 tee actually do for me on the job?
Smart Connect is a deliberate feature in the sealing element that lets an unpressed connection leak during pressure test, so an inspector or the installer finds the missed joint on the test rather than after the wall closes. On a 4 inch tee in an overhead run that's the difference between a quick fix and a tear-out.
6) What is the exact Viega part number to order for the 4 x 4 x 3/4 stainless MegaPress tee?
Order Viega 98430. That's the manufacturer part number for the 316 stainless MegaPress tee in 4 inch x 4 inch x 3/4 inch FPT.
