Viega 90840 – Frequently Asked Questions
1) What pipe size does the Viega MegaPress 90840 45-degree elbow fit?
The 90840 is a 1-1/4 inch by 1-1/4 inch fitting, press on both ends. Viega MegaPress is the carbon steel pipe system, so it presses onto 1-1/4 inch black iron or carbon steel pipe at both connections. Both ends are press (P1 x P2), so there is no threading or welding at either joint.
2) Is the Viega 90840 elbow stainless steel or carbon steel?
The 90840 elbow body is 316 stainless steel. That is the corrosion-resistant grade, which matters on wet or chemically aggressive service and in mechanical rooms where condensation sits on the fitting. It is made in Germany.
3) What is Smart Connect on the Viega MegaPress 45-degree elbow, and why does it matter on an install?
Smart Connect is the feature Viega builds into the 90840's sealing element so an unpressed connection leaks visibly during pressure test rather than passing inspection and failing later. On a large run with dozens of joints, that is how a crew finds the one fitting the tool missed before the ceiling closes up.
4) How much room do I need to allow for a 1-1/4 inch MegaPress 45 elbow in a tight chase?
Plan the space from the fitting's published envelope: 5.543 inches long, 3.85 inches wide, 2.205 inches high. You also need clearance around the joint for the press jaw to close fully on both ends, which is usually the real constraint in a chase or next to a joist, not the fitting itself.
5) Can I use the Viega 90840 to make a 45-degree offset around an obstruction?
That is what it is for. Two 45-degree elbows let you jog a 1-1/4 inch carbon steel line around a beam, duct or another pipe with a gentler change of direction than a pair of 90s, which keeps pressure loss down. Both ends press, so the offset goes together cold with no threading or hot work.
6) Do I need a special press tool or jaw for the Viega 90840?
MegaPress joints are made with a press tool and the MegaPress jaw or ring sized for 1-1/4 inch pipe. The 90840 ships as the fitting only, with its sealing element already installed, so the tool, the correct size jaw, and a pipe cutter and deburring tool are what you supply.
7) What is the exact part number and weight of the Viega 1-1/4 inch MegaPress stainless 45 elbow?
Order it as Viega part 90840. Each fitting weighs 1.042 lbs, which is worth knowing when you are pricing freight on a full bag of fittings for a large press job.
