Fabricated mitered fittings
(ie: elbows, line tees, line crosses and wyes) are generally rated
at 80% of the pressure rating of the SDR of material that is used
for the fitting (ie: a mitered fitting produced using SDR-11 160
psi material would be pressure rated for a working pressure of 128
Fully pressure rated
mitered fabricated fittings will be constructed using the next size
heavier SDR material available (ie: fittings rated for a SDR-11
160 psi working pressure rating would be manufacturing using SDR-9
Other fabricated fittings
such as branch saddle tees, branch saddle wyes, fabricated concentric
reducers and waterstops are normally pressure rated to the SDR ordered.
Fabricated fittings are stocked in most SDR's listed.
