Viega 28635 MegaPressG 45° elbow Smart Connect technology Carbon steel, 3'' x 3''

Both ends of the Viega 28635 are press connections, listed as P1 x P2, so it goes in with a press tool and MegaPress jaws rather than threading or welding. Nothing on the fitting is threaded, so if you need to land on a threaded valve or male nipple you'll want a press-by-thread adapter to finish that side.

It is a 3 inch by 3 inch fitting, so both ends press onto 3 inch pipe. Same size in and out, no reduction through the elbow.

Carbon steel. That is what makes it a match for black iron pipe runs, which is the pipe MegaPressG systems are used on. Don't substitute it into a copper or stainless line where dissimilar metal contact matters.

Viega part number 28635. Ordering by size alone is risky with MegaPress since the G series for gas and the standard MegaPress line carry different numbers, so quote 28635 when you order the carbon steel 3 inch 45.

A 45 lets you offset around an obstruction or come off a riser at an angle without the pressure drop and extra joint count of stacking 90s. Each press joint is another potential leak point and another tool cycle, so on 3 inch carbon steel the 45 is usually the cleaner route. The 28635 gives you that turn with press ends on both sides.

Smart Connect is Viega's unpressed-joint indicator. During pressure testing an unpressed fitting leaks noticeably so the installer can find and press it, rather than having a missed joint show up after the system is charged. On a 3 inch line with a dozen joints that is the difference between a five minute fix and chasing a leak behind finished work.

Germany. That matters on federal, state and institutional jobs where country of origin has to be documented in the submittal package, so check the origin requirement on your spec before you commit to it.
