Pipe insulation for 1-1/4" pipe

This black elastomeric pipe insulation fits 1-1/4 inch pipe and 1-5/8 inch tube with a 1 inch wall thickness. The six-foot length covers residential and commercial plumbing runs. The NBR/PVC based material suits hot and cold water lines in new installations or retrofit projects.

Operating range and thermal rating

The insulation performs from minus 297 degrees F to 220 degrees F and carries an approximate R-value of 6.6. This wide temperature span supports chilled water, refrigeration and hot water systems without additional jacketing in normal indoor use.

Unslit construction and daily handling

The unslit body requires cutting to length and sealing at joints during installation. The flexible elastomeric material bends around fittings without kinking and the black finish resists UV exposure on exposed runs. California Proposition 65 applies to this product.

Questions about this item

How do I install the 1 in wall thickness insulation on a 1-1/4 in pipe and what step is often missed?

Slide the unslit tube over the pipe before final connections, then seal the seam with compatible adhesive tape; skipping the tape leaves a thermal bridge.

What maintenance or replacement will the NBR/PVC elastomeric insulation need over time?

Inspect annually for UV cracking or compression set; replace sections that have lost thickness or show surface degradation to maintain the R 6.6 value.

At what temperature limit does the insulation reach its maximum rated performance during sustained use?

Continuous exposure at 220 °F is the upper service limit; beyond this the material can degrade and lose insulating effectiveness.
