Pipe insulation for 2-inch lines

This unslit tube fits 2-inch pipe and runs 6 feet with a 3/4-inch wall. The NBR/PVC elastomeric body carries an approximate R-value of 4.4 and withstands temperatures from -297 °F to 220 °F. It suits residential and light-commercial plumbing runs that need thermal protection.

Push-on installation with basic tools

Slide the tube over clean, dry pipe and seal the seam with compatible adhesive tape or glue. Common issues include gaps at butt joints and compression at hanger points, both of which reduce the rated R-value if not taped and supported properly.

Verify pipe diameter and temperature limits

Confirm the line measures 2 inches outside diameter so the 2 3/8-inch nominal bore seats without stretching. Ensure the system never exceeds 220 °F or drops below -297 °F, and check local code for any Proposition 65 disclosure requirements.

Questions about this item

How can I confirm the insulation is performing correctly after installation?

Measure the surface temperature of the pipe; it should remain within the rated range of -297 to 220 degrees F and feel consistent along the 6 ft length.

What comes in the box and what must I supply?

The package contains the 6 ft length of 3/4 in wall pipe insulation; you will need to provide adhesive, tape or mechanical fasteners to secure the unslit seam.

Which version should I select for a 2 in pipe?

Choose the 2 in nominal size with 3/4 in wall thickness, which delivers an approximate R-value of 4.4 and fits a 2 3/8 in nominal inside diameter.
