Viega 91310 – Frequently Asked Questions
1) What pipe size does the Viega MegaPress 91310 coupling join?
The Viega 91310 MegaPress coupling is a 1-1/2 inch by 1-1/2 inch fitting, so it joins two runs of 1-1/2 inch pipe with press connections on both ends (P1 x P2). It is not a reducer, both ends are the same size.
2) What does "no stop" mean on the Viega 91310 MegaPress coupling, and when do I need that version?
A no-stop coupling has no internal pipe stop, so the fitting can slide freely along the pipe. That is what you want for a repair or tie-in where neither pipe end can be moved: slide the coupling over the cut, center it on the joint, mark your insertion depth, and press both ends. If both pipe ends are free to move, a stop version is easier because the stop sets the depth for you. The 91310 is the 1-1/2 inch x 1-1/2 inch no-stop in 316 stainless.
3) Is the Viega 91310 coupling suitable for corrosive or washdown service?
It is built from 316 stainless steel, the grade specified where chloride exposure and corrosion resistance matter, such as washdown areas, coastal installs, and chemical or process lines. For ordinary carbon steel pipe in dry mechanical rooms, the carbon steel MegaPress body is the usual choice, 316 is the upgrade.
4) What is Smart Connect on this MegaPress fitting and why does it matter on the job?
Smart Connect is Viega's unpressed-connection feature: the sealing element is shaped so an unpressed fitting leaks visibly during pressure test rather than holding and failing later. On a large install, that is how you find the joint you missed before you close the ceiling. The 91310 coupling carries it.
5) How much clearance do I need around the pipe to install the Viega 91310?
The coupling body measures 4.713 inches long and 2.437 inches across, so plan on roughly that envelope plus room for the press jaw to close fully around the fitting. Tight against a wall or joist, the jaw, not the fitting, is usually what runs out of space.
