The math, done right, on the job
- Offset: travel, run and the pipe cut length between two elbows, for 11¼°, 22½°, 30°, 45°, 60° or any angle
- Rolling offset: set + roll → true offset, travel, run and how far to roll the fittings — or the fitting angle that fits a fixed run
- Parallel offsets: the shift that keeps the spread equal through an offset in a rack
- Miter cuts: cut angle, cut-back and long-side / short-side lengths for 2- to 6-piece miters
- Fitting take-outs: ASME B16.9 butt-weld elbows, tees and reducers, ½″ to 24″, and elbows cut to any angle
- Type feet, inches and fractions on a big keypad; answers to the nearest 1/8, 1/16 or 1/32 with the exact decimal underneath

Pipe Fitter is a calculator. Check every measurement against your drawings and the fittings in your hand before you cut. Fitting dimensions are for ASME B16.9 butt-weld fittings; socket-weld, threaded, grooved and copper fittings differ.
