Viega 91935 – Frequently Asked Questions
1) What size pipe does the Viega 91935 MegaPress union fit?
The Viega 91935 MegaPress union is a 1 inch by 1 inch fitting, press on both ends (P1 x P2). It joins two runs of 1 inch pipe, so both sides have to be 1 inch nominal for the press jaw to seat correctly.
2) Is the Viega 91935 union threaded or does it need a press tool?
Both ends are press connections (P1 x P2), so you need a press tool with the correct MegaPress jaw for 1 inch. There are no threads and no soldering. Nothing in the joint is made up by hand, which is why the fitting can go in on a wet line without draining the system down.
3) What material is the Viega 91935 MegaPress union made of, and will it hold up in a corrosive environment?
It is 316 stainless steel. 316 is the molybdenum-bearing grade, which is what gets specified where chlorides or washdown chemicals are in play, so it suits food processing, coastal, and industrial service better than a carbon steel fitting.
4) Can I mix the Viega 91935 stainless union with carbon steel MegaPress fittings on the same line?
Keep the material consistent. The 91935 is a 316 stainless steel fitting and is intended for stainless piping systems. Putting stainless directly against carbon steel pipe sets up a dissimilar metal couple at the joint, so if your run is carbon steel you want the carbon steel MegaPress fitting instead, not this one.
5) How much clearance do I need to install a Viega 1 inch MegaPress stainless union?
The fitting itself measures 5.37 inches long, 2.26 inches wide and 2.087 inches high, and it weighs 1.358 lbs. Plan the space around that body plus whatever your press jaw needs to swing, which is usually the limiting factor in a tight joist bay or against a wall.
6) What does Smart Connect do on the Viega 91935 union?
Smart Connect is Viega's unpressed-joint feature: if a connection gets missed during a pressure test, it leaks at that joint so you find it before the system is closed up. It is a commissioning aid, not part of the seal on a properly pressed connection.
7) Why use a union here instead of just pressing a straight coupling?
A union gives you a disconnect point. Press couplings are permanent, so if you need to pull a pump, valve, or section of pipe for service later, the 91935 union at 1 inch lets you break the line without cutting it. Typical spots are either side of equipment or at a tie-in that gets serviced.
