Pipe insulation for 1-1/8" copper tube
This closed-cell tube fits 1-1/8 inch inside diameter copper piping and provides a 3/4 inch wall thickness. It is sold in a six-foot length with an unfaced black finish. The product suits HVAC, plumbing and refrigeration lines that need thermal protection.
Operating range from -297 °F to 220 °F
The Buna-N rubber and PVC foam remains flexible across the full temperature span. A flame spread index of 75 and smoke developed index of 100 support plenum-rated installations. The material carries an R-value of 5.5 for consistent thermal resistance.
Replaces worn or missing pipe wrap
Builders use this tube to upgrade bare copper or deteriorated insulation on 3/4 inch pipe size runs. The unslit form requires cutting and sealing on site. It is not suited for applications that demand a pre-slit or self-sealing sleeve.

Questions about this item
How do I install the unslit tube on an existing pipe?
Slit the 6 ft length lengthwise with a sharp knife, wrap it around the 1 1/8 in copper tube, then seal the seam with compatible adhesive tape or glue.
What maintenance does the closed-cell NBR/PVC foam need over time?
Inspect the 3/4 in wall periodically for tears or UV damage; replace any section where the vapour barrier is broken to keep the R-5.5 value intact.
At what temperature does the insulation reach its upper service limit?
The material is rated to 220 °F maximum operating temperature; sustained exposure above that will degrade the Buna-N rubber/PVC blend.
