  • Ready to install as a 6-foot unslit length for 3/8-inch pipe
  • Prop 65 warning included for California regulatory compliance

Pipe insulation for 3/8" pipe

This unslit pipe insulation fits 3/8 inch pipe and 5/8 inch tube with a one inch wall thickness. The six foot length is made from NBR/PVC based elastomeric material in black. It is designed for thermal protection on plumbing and HVAC lines. The product is supplied new and ready for installation.

Suitable for residential and commercial piping

Installers insulating hot or cold water lines, refrigerant tubing or condensate drains will find this size appropriate. It is not suited for projects requiring pre-slit insulation with self-seal closure or for pipe diameters outside the 3/8 inch nominal size. Buyers needing different wall thicknesses or lengths should select another product.

Operating temperature range and R-value

The insulation performs across a range of -297 degrees F to 220 degrees F and provides an approximate R-value of 7.2. These figures determine whether the material meets the thermal demands of a specific application. A Proposition 65 warning applies due to regulated chemical content.

Questions about this item

Should I choose the 3/8 in pipe size or the 5/8 in tube size for my installation?

Match the insulation to the outside diameter of your pipe; the nominal inside diameter is 5/8 in, which fits a 5/8 in tube or a 3/8 in pipe size.

What does the R-value of 7.2 mean once the insulation is installed?

An R-value of 7.2 indicates high thermal resistance, reducing heat loss or gain across the 1 in wall thickness in typical plumbing runs.

How does the NBR/PVC elastomeric material perform at the rated temperature limits?

The NBR/PVC blend remains flexible and effective from -297 °F up to 220 °F, covering most residential and commercial hot and cold water lines.
