This PVC coupling features 1/2" Slip x 1/2" Slip connections, designed to join two pieces of plumbing pipe or attach to a fitting. Both ends have an inside diameter of 3/4", making it compatible with rigid or flexible PVC pipe applications in spa systems.
Understanding PVC Sizing: The nominal size designation of PVC fittings refers to the Inside Diameter of the pipe that inserts into the fitting, not the actual opening measurement you can see. To help you select the correct fitting, we provide the Outside Diameter measurements of the pipe. For instance, a fitting labeled 1/2" will accept pipe measuring 3/4" on the outside diameter.
Pipe Outside Diameter Reference Guide:
½" Outside Diameter is ¾"
¾" Outside Diameter is 1"
1" Outside Diameter is 1 ¼"
I have never seen 1 ¼" in Hot Tubs
1 ½" Outside Diameter is 1 ⅞"
2" Outside Diameter is 2 ⅜"
2 ½" Outside Diameter is 2 ⅞"
