Viega 84345 – Frequently Asked Questions
1) What size pipe does the Viega MegaPress 84345 45-degree elbow fit?
The MegaPress 84345 is a 1 inch by 1 inch 45-degree elbow, press on both ends (P1 x P2). It joins two runs of 1 inch carbon steel pipe at a 45-degree offset. For any other line size you need a different MegaPress elbow; this body is fixed at 1 inch on both ports.
2) Is the Viega 84345 elbow threaded or does it need a press tool?
Both ends are press connections (P1 x P2), so it is installed with a press tool and jaw sized for 1 inch MegaPress, not threaded or welded. Nothing is cut, threaded, or flame-joined on the pipe end, which is why it gets specified for occupied buildings and hot work permit areas.
3) Can I use a MegaPress carbon steel elbow on black iron pipe?
The 84345 is a carbon steel fitting made for black iron / carbon steel pipe systems. It is not a copper or stainless fitting, so do not press it onto copper tube or stainless line; those systems take Viega's copper or stainless press fittings instead.
4) What is Smart Connect on this Viega elbow and why does it matter on a pressure test?
Smart Connect is the feature built into the 84345's sealing element that leaves an unpressed connection deliberately leaky during test. On a system fill, a joint you missed weeps instead of holding, so you find it at test rather than after the ceiling is closed. It does not change how the finished press joint performs once made up.
5) How much space does the 1 inch MegaPress 45 elbow take up in a tight ceiling?
Overall the fitting measures 4.386 by 3.071 by 1.78 inches and weighs 0.661 lbs. That footprint is what you need to clear for the press jaw as well as the fitting itself, so budget extra beyond the raw dimensions for the tool to close around each end in a joist bay or tight riser chase.
6) Should I use a 45-degree elbow or a 90 for offsetting around an obstruction?
Use a pair of 45s like the 84345 when you need to jog a 1 inch carbon steel line around a beam or duct and come back parallel to the original run. A 90 turns the line and leaves it turned. Two 45s also give a gentler direction change and less added length than routing with two 90s, which matters on long horizontal runs.
