Viega 84335 – Frequently Asked Questions
1) What pipe does the Viega MegaPress 84335 45-degree elbow press onto?
The MegaPress 84335 is a carbon steel press fitting with two press ends (P1 x P2) sized 1/2 inch by 1/2 inch. MegaPress fittings press onto black iron / carbon steel pipe, so it joins 1/2 inch steel pipe on both ends with no threading, welding or cutting oil. If you need a threaded transition instead, you want a press x FNPT or press x MNPT adapter, not this fitting.
2) Can I use a carbon steel MegaPress elbow on a potable water line?
No. The 84335 is carbon steel, and carbon steel press fittings are for non-potable systems such as hydronic heating, chilled water, compressed air, fire protection and gas where the system design allows. For potable water you need copper or stainless press fittings instead.
3) How much space does the Viega 84335 45-degree elbow take up in a tight chase?
Compact. The fitting measures 3.295 inches long, 2.252 inches wide and 1.264 inches high, and it weighs 0.315 lbs. The thing to plan for is not the fitting size but swing room for the press tool jaw around each of the two press ends.
4) What does Smart Connect technology on a Viega MegaPress fitting actually do for the installer?
Smart Connect is a feature of the MegaPress sealing element that lets an unpressed connection leak intentionally during pressure testing, so an installer or inspector can spot a joint that was missed before the system goes into service. It does not change the fitting's size or connection type: the 84335 is still a 1/2 inch press x press 45-degree elbow that has to be pressed with the correct jaw.
5) Do I need a 45-degree elbow or a 90 for offsetting around an obstruction?
Use a pair of 45s when you are jogging a line around a beam, duct or wall offset and want to keep flow direction and minimize pressure drop. Model 84335 is the 45-degree version in 1/2 inch press x press. A 90-degree elbow is the right part for a full change of direction at a corner or a drop. For a long sweeping offset, two 84335 elbows with a short nipple of 1/2 inch steel pipe between them is the usual approach.
6) Is the Viega 84335 MegaPress elbow threaded at all, and do I need pipe dope?
There are no threads on it. Both ends are press connections (P1 x P2), so there is no dope, tape, cutting or welding involved. Pipe is cut square, deburred, marked to depth, inserted fully into the fitting and pressed with the matching MegaPress jaw. No sealant is added to a press joint.
7) Is the Viega 84335 MegaPress elbow made in the USA?
No, it's made in Germany. That matters if you are bidding public work with domestic sourcing requirements, so check the spec on the drawing before you commit it to a government or federally funded job.
8) What exact part number do I order for a 1/2 inch Viega MegaPress 45-degree elbow?
Order Viega MegaPress part number 84335. It is the 1/2 inch x 1/2 inch carbon steel 45-degree elbow with press ends on both sides.
