Viega V19748 – Frequently Asked Questions
1) What exactly comes in the Viega 19748 flange bolt set?
The Viega 19748 is a flange bolt set in galvanized carbon steel, supplied as a bolt set for a flanged connection. The published sizing reads 2-3/8" x 5/8" - 4, 1/2" - 1-1/2", and the set weighs 0.871 lbs. It is hardware for making up a flange joint, not a fitting body, so the flange, gasket and pipe are separate items.
2) Do I need anything besides the 19748 bolt set to make up the flange joint?
Yes. The 19748 supplies the bolting only. You still need the mating flange or flange adapter, the gasket, and the pipe or fitting being joined. Plan on a torque wrench as well, since flange bolts are cross-torqued in stages rather than run down with an impact.
3) Is Viega part 19748 the same thing as model 2959.7?
Yes. 2959.7 is Viega's model designation for the flange bolt set ordered as part number 19748. If a submittal or takeoff lists 2959.7, ordering 19748 gets you the same galvanized carbon steel bolt set.
4) Will a galvanized carbon steel flange bolt set corrode on a potable water or hydronic job?
The 19748 bolt set is galvanized carbon steel, so the zinc coating handles normal indoor mechanical room and hydronic service. The bolts sit outside the wetted path of the joint, clamping the flange faces, so they do not contact the fluid. For continuously wet, washdown, coastal or corrosive process areas, spec a stainless bolt set instead.
5) How many bolt sets do I need to order for a run with several flanged joints?
One 19748 set per flange joint. Each set covers a single connection, so a run with four flanged breaks takes four sets. Buyers standardizing a mechanical room usually add a spare or two, since a dropped or galled bolt on a galvanized set is not something you want to hunt for mid-shift.
