Insulation for 2-1/8" pipe

This elastomeric foam tube fits 2-1/8 inch outside-diameter piping and comes in a six-foot length with a one-inch wall. It is intended for plumbing, HVAC or industrial lines that need thermal protection. The NBR/PVC blend resists moisture and remains flexible across a wide temperature span. Supplied unslit so the installer can cut and seal it on site.

Installers needing continuous runs

Suits contractors who want a single six-foot piece to cover straight sections without joints. The unslit design requires a knife and adhesive tape for fitting around bends, valves or existing pipework. Not for buyers who need pre-slit, self-sealing sleeves or shorter pre-cut lengths for tight retrofits. The material carries a Proposition 65 warning, so projects with strict chemical-restriction specs should verify compliance first.

R-value 6.1 at one-inch wall

The published thermal resistance is 6.1, which determines how well the insulation limits heat loss or gain on the pipe. Operates continuously from minus 297 degrees Fahrenheit up to 220 degrees Fahrenheit. Match this R-value and temperature range to the system design calculations before purchase.

Questions about this item

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

Check that the pipe surface temperature stays within the -297 °F to 220 °F operating range and that no condensation forms on the outer jacket during normal system operation.

What comes in the box and what must I purchase separately?

The package contains one six-foot length of black NBR/PVC elastomeric pipe insulation with a one-inch wall for 2-1/8 inch tubing; adhesive, tape, vapor-barrier coating and cutting tools are not included.

Which specification should I match when selecting this insulation for my pipe?

Choose this model when your tubing outside diameter is 2-1/8 inches and you need a one-inch wall thickness providing an approximate R-value of 6.1.
