Use regular central vacuum pipe (2″ / 51 mm outer diameter) for the straight runs. Keep the following in mind:
Deburr all pipe ends
Limit each valve to a maximum of four Hide-A-Hose 90° fittings
Do not deform the pipe or fittings out of round
Do not install any tees or wyes in the line until the stored hose ends in the Hide-A-Hose pipe run
Each Hide-A-Hose 90° fitting needs 12″ / 305 mm of space to make the turn
Hide-A-Hose fittings are available in 90°, 45°, and 22.5°.
