Short answer

S&D pipe is PVC sewer-and-drain pipe made to ASTM D2729, a plumbing standard whose active edition is D2729-21 and which does not address dust collection. Rockler says S&D does not connect directly to most dust fittings without an adapter, and WoodRiver's 4 in adapter fits inside S&D with a 4.065 in ID but works only with left-hand threaded hose. The catch: no S&D outside diameter or wall figure is confirmed here. See S&D vs Schedule 40.
