Fits 1/2" pipe with 1" wall

Nomaco Kflex 6RX100078 pipe insulation fits 1/2 inch pipe and 7/8 inch tube with a 1 inch wall thickness. The unslit black NBR/PVC elastomeric tube runs 6 feet long. It suits plumbing systems that need thermal protection on small-diameter lines. Buyers who want pre-slit or adhesive-backed wrap cannot use this item.

Temperature range from -297°F to 220°F

The material withstands continuous service from minus 297 degrees Fahrenheit up to 220 degrees Fahrenheit. An approximate R-value of 7.0 provides consistent thermal resistance across that span. Systems operating beyond these limits need different insulation. California Proposition 65 warning applies because the product contains a listed chemical.

Push-on installation on unslit tube

The unslit tube slides over pipe before fittings are made, so joints stay continuous. A sharp knife and contact adhesive are the only tools required for a clean seal. Installers who skip adhesive at seams risk condensation leaks. The product is new and ships as a single 6-foot length.
