Schedule 40 PVC Slip Reducing Coupling-Slip Size Slip Size:1/2 inch

This Schedule 40 PVC Slip x Slip Reducer Coupling is used to transition from one size PVC pipe to another in a straight connection. Slip connections require primer/glue. Selecting the correct size fittings to match your PVC pipe can be confusing if you do not already know what size PVC pipe you have. All plumbing grade PVC should have size and rating information imprinted on the outside of the pipe. PVC pipe is named for the inside diameter, commonly referred to as “a nominal size”. If not able to locate this information then simply measuring the inside or outside diameter will help you determine the correct pipe size using the chart below. **PVC Pipe Size Table** Nominal PVC Pipe Size **1/2 inch** **3/4 inch** **1 inch** **1 1/4 inch** **1 1/2 inch** **2 inch** Average Inside Diameter 0.622 inch 0.824 inch 1.049 inch 1.380 inch 1.610 inch 2.047 inch Actual Outside Diameter 0.840 inch 1.050 inch 1.345 inch 1.660 inch 1.900 inch 2.375 inch Once you determine your PVC pipe size then fitting selection is easy – just match the nominal pipe size to the corresponding fitting size. Example: If your pipe measures 0.824 inch ID (inside diameter) which is 3/4 inch PVC pipe, you will select 3/4 inch PVC fitting.
