Purpose:  The charts above are used to identify the size number of a PVC fitting for a certain size insulated pipe.

Directions: PVC sizes are different depending on the type of pipe you are insulating.  If you are insulating an Iron pipe use the top chart, use the bottom chart for Copper pipe.  The column on the left is diameter of the pipe and the top row is the thickness of the insulation on the pipe.

Example: If you are insulating a 3" Iron pipe with 1" fiberglass pipe insulation you would use a #13 PVC Fitting.  If you are insulating a 3" Iron pipe but with 1.5" fiberglass pipe insulation you would use a #15 PVC Fitting.  Please contact us with any questions and we will happily advise you on what PVC fittings to order.
