Fiberglass Pipe Insulation
This common insulation material is typically used on hot and cold water lines and in process piping. To use outdoors, add metal jacketing.
Tubes, elbows, and tees are formed to provide the best fit on pipe and are the easiest to install. If your pipe is larger than the sizes we offer, choose a sheet/strip.
Elbows and tees with PVC jacketing seal using reinforced HVAC tape (sold separately). Tees have a capped top and open sides. The top can be cut as needed.
