Fittings & Routing · Expanded master guide
Elbows & Offsets
Ten expanded field guides for rectangular and round elbows, offsets, compound fittings, vane access sections, and vertical-to-horizontal riser turns.
Do not use a fitting to hide a bad route.
Establish both centerlines, support the fitting body, match the correct plane and orientation, and stop before forcing a joint or twisting the fitting.
