Viega 95805 – Frequently Asked Questions
1) What size pipe does the Viega MegaPress 95805 coupling press onto?
The Viega 95805 MegaPress coupling is a 1-1/4 inch by 1-1/4 inch fitting, so it joins two runs of 1-1/4 inch pipe with a press connection on each end (P1 x P2). It is a straight coupling, not a reducer, so both sides must be the same 1-1/4 inch size.
2) What does "no stop" mean on the Viega 95805 MegaPress coupling?
No stop means there is no internal shoulder inside the coupling body, so the pipe can slide straight through. That is what you need for a repair or tie-in where you cannot pull the pipe apart: slide the coupling along the existing line, position it over the joint, then press both ends. A standard coupling with a stop has to be fed onto a free pipe end instead.
3) Can I use the Viega MegaPress 95805 coupling on black iron or carbon steel pipe?
MegaPress fittings are the press system for black iron and carbon steel pipe, and the 95805 is built in 304 stainless steel with a press end on each side. Note that this is the stainless steel body version rather than carbon steel, so confirm your spec calls for the 304 body before ordering.
4) How much space do I need around the pipe to press the Viega 95805 coupling?
The coupling body itself measures 4.429 inches long and 2.205 inches in both height and width, so plan on clearance for that envelope plus room for the press jaw to close around it. Tight ceiling spaces and pipe close to a wall or joist are the usual problem spots.
5) What is Smart Connect technology on a Viega MegaPress fitting?
Smart Connect is a feature of the sealing element that deliberately leaks a small amount when the joint is pressurized but has not been pressed. On a 50 or 100 joint rough-in it is how you find the one connection you missed during pressure testing, rather than discovering it after the ceiling closes.
6) Should I use a press coupling like the Viega 95805 instead of threading or welding the repair?
A press coupling makes the joint cold, with no torch, no pipe dope and no threading machine, which matters in occupied buildings and anywhere a hot work permit is a problem. Because the 95805 is the no stop version, it also handles the case threading and welding make hard: an in-line repair on pipe that cannot be shifted. The trade-off is that you need the matching press tool and jaw for 1-1/4 inch.
7) Is the Viega 95805 coupling corrosion resistant enough for a mechanical room or exposed run?
The body is 304 stainless steel, which is the grade used where carbon steel fittings would be at risk from moisture or washdown. It weighs 0.849 lbs, so supporting the line is no different than with a threaded or welded fitting at this size.
