What is the Hose barb size connector for SDR 7 IPS PS24 ASTM02239 PS-11-69 3/4 IPS. 160PSI. Fresh water from water meter to the house. The OD of poly pipe is 1.075. Guess the wall is 0.100 . So the hole is apx 0.800. Do you use a standard 0.750 barb in it and pull the pipe down with a clamp? Or can you find a barb fitting that is oversized? Anyone have a source? Thanks.
