I'm building a housing for my video camera using the simple pipe-with-a-cap method, almost everyone I see making housings use PVC, and I understand that PVC is pressure rated so the argument of why PVC is used isn't an issue for me. The issue is that Home Depot only has ABS pipe large enough to fit my camera (4"...and that's cutting it close) I picked up two feet to start the job on but I can't find any information relating to pressure handled by ABS ANYWHERE online, short of buying the ASTM specs for $50 to download. Does anyone know how much pressure 4" sch 40 cellular core ABS can hold? It'll need to hold up and be useable at 100' max. Should I toss it in a dumpster and travel farther until I get my hands on PVC?
