From Pathfinder Wiki
A six-hole transverse flute can be made from a 3/4" (19mm) diameter length of PVC (or CPVC) pipe. PVC is used for plumbing cold water supply lines, and CPVC is used for hot water supply lines. Do not use ABS, as it is used for plumbing waste lines, and is therefore not regulated in regard to toxicity. For the same reason, you should not use plastic electrical conduit.
