Viega 98415 – Frequently Asked Questions
1) Is the Viega 98415 MegaPress elbow for 4 inch pipe on both ends?
Yes. The 98415 is a 90 degree MegaPress elbow sized 4 inch by 4 inch, with a press connection on each end (P1 x P2). Both ends press onto 4 inch pipe, so it turns a run without any adapter.
2) What material is the Viega 98415 MegaPress elbow, and will it hold up in a corrosive line?
It's 316 stainless steel through the body. 316 is the molybdenum-bearing austenitic grade, which is why it's specified over 304 where chlorides or wash-down chemicals are in play, and it's also the choice when the system has to stay non-ferrous on the wetted side.
3) Do I need to solder or thread this 4 inch Viega elbow, or is it a press fitting?
It presses. Both ends of the 98415 are MegaPress press connections, so the joint is made cold with a press tool and jaw sized for 4 inch, no flame, no threading, no cutting oil. That's the reason crews use it on occupied buildings where hot work permits are a problem.
4) What does Smart Connect mean on the Viega MegaPress 98415?
Smart Connect is the feature built into the sealing element that lets an unpressed joint leak visibly during pressure testing, so an installer finds a missed press before the ceiling closes up. On a 4 inch elbow that matters, because a large-diameter fitting high in a run is exactly the one that gets skipped.
5) How much space do I need to fit the 4 inch Viega 98415 elbow, and how heavy is it?
Plan for a fitting measuring 11.772 by 11.772 by 5.193 inches and weighing 8.036 lbs. At that size and weight it needs to be supported and aligned before pressing, and you need jaw clearance around the collar on both legs, which usually means roughing in the hanger locations first rather than pressing in a tight chase.
6) Is the 316 stainless MegaPress elbow the same as the carbon steel MegaPress fitting?
No, and they are not interchangeable in a spec. The 98415 is 316 stainless steel, which is the version used where the piping system itself is stainless or where corrosion rules out carbon steel. If the run is black iron or carbon steel pipe, the stainless body is the wrong material pairing for that system. Match the fitting material to the pipe material.
7) What is the exact part number and manufacturer for ordering this 4 inch 90 degree stainless press elbow?
Viega, part number 98415. It's the MegaPress 90 degree elbow in 316 stainless, 4 inch by 4 inch, made in Germany. Distributors ordering against a submittal should quote 98415 directly, since the stainless and carbon versions of MegaPress elbows carry separate numbers.
