Or is it a pack** A: Single flange **Q: I'm looking for a 1/2" flange to use with schedule 40 pvc but can't find it. will this fit schedule 40 as well?** A: The diameter of the schedule 80 and schedule 40 PVC pipes is the same, so for this flange, they are interchangeable. Schedule 80 pipe has a thicker wall and is designed for higher pressure. Both will fit nicely into this flange and can be glued using PVC glue. **Q: what is the inside dimension of the 2-1/2 inch slip socket?** A: The outside diameter of a standard 2-1/2 inch pipe is 2-7/8 (2.875) inches. So, the inside diameter of the slip socket should be about that (or just very slightly more).
