Pipe insulation for 3 1/8-inch tubes

This Nomaco Kflex pipe insulation fits tubes with a nominal inside diameter of 3 1/8 inches. It uses an NBR/PVC-based elastomeric material in a black finish. The unslit design comes in a six-foot length with a one-inch wall thickness. It suits plumbing and HVAC applications requiring thermal protection.

Check tube size and installation method

Verify that the pipe outer diameter matches the 3 1/8-inch nominal inside diameter before ordering. The unslit tube requires sliding over the pipe end or cutting a slit during installation. Ensure the operating temperature stays within the rated range of -297 to 220 degrees Fahrenheit. Confirm local codes accept elastomeric insulation for the intended use.

Elastomeric body with Proposition 65 notice

The NBR/PVC elastomeric wall provides an approximate R-value of 5.6 for thermal resistance. Black colour helps the insulation blend with standard pipework. A California Proposition 65 warning applies because the product contains a listed chemical. Handle with appropriate protective equipment during cutting or fitting.

Questions about this item

What comes in the box with the Nomaco Kflex 6RX100318 and do I need to buy adhesive or tape separately?

The product is a single 6 ft length of 1 in wall unslit pipe insulation. Adhesive or sealing tape is not included and must be purchased separately for installation.

Which size should I choose if my copper tubing measures 3 1/8 in outside diameter?

This model is manufactured with a nominal 3 1/8 in inside diameter to fit that exact tube size. No other diameter is offered under this part number.

What does the R‑5.6 rating mean for my hot‑water or refrigeration line once the insulation is installed?

R‑5.6 indicates the thermal resistance of the 1 in thick NBR/PVC foam, reducing heat loss or gain across the operating range of ‑297 °F to 220 °F.
