Purpose:  The charts above are used to help identify the size PVC Cut & Curl Jacketing needed for an insulated pipe. 

Please keep in mind that the PVC Jacketing size is different than all other PVC Fitting Cover sizes.

Directions: PVC Cut & Curl Jacketing sizes are different depending on the type of pipe you are insulating.  If you are insulating an Iron pipe use the left chart (IRON PIPE), use the right chart for Copper pipe (if you already converted your copper pipe size to the correct iron pipe size, use the iron pipe size and the left chart).  The column on the left is the size 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 5.5 PVC Jacketing.  If you are insulating a 3" Iron pipe but with 1.5" fiberglass pipe insulation you would use a 6.5 PVC Jacketing.  Please contact us with any questions and we will happily advise you on what PVC fittings to order.
