Pipe insulation for copper tube size

This flexible tube insulation fits 1-1/4 inch pipe and 1-1/2 inch copper tube size. It is made from halogen-free Buna-N rubber with a closed-cell foam structure. The product comes in a six-foot length with a 3/4 inch wall thickness. It is supplied new and unslit for custom fitting.

Plumbers and HVAC installers

This insulation suits professionals who need plenum-rated material with a flame spread index of 25 and smoke developed index of 50. It handles continuous temperatures from -40 to 250 degrees Fahrenheit. It is not for buyers who require a pre-slit design or an adhesive facing for faster installation.

R-value 4.3 thermal performance

The insulation delivers an R-value of 4.3 to reduce heat loss and control condensation on hot or cold lines. The green colour identifies the halogen-free elastomeric formulation. This single figure determines whether the thermal resistance meets your project specification.

Questions about this item

How often will the HAWA elastomeric tube need replacing once installed?

The closed-cell Buna-N rubber is halogen-free and rated for continuous service between -40 °F and 250 °F, so it does not require scheduled replacement under normal conditions.

What performance limit appears first when the insulation runs at high temperature all day?

The material stays within its 250 °F maximum operating temperature, and the 25 flame spread / 50 smoke developed indices are not exceeded, so thermal degradation is the first boundary.

Does the green unfaced tube generate noticeable heat or noise during constant operation?

As passive pipe insulation it produces no noise and adds negligible heat; its R-value of 4.3 simply reduces thermal loss from the 1-1/4" copper line.
