Our take on the K-Flex USA Thermal Insulation Sheet 6rshfg

This is a flexible Buna-N rubber insulation sheet with a self-adhesive backing, sold in 4 ft lengths for wrapping ducts, pipes and equipment. It handles -40 °F to 200 °F and carries ASTM C534 and EB4013 listings. The listed R-value is 1.85, though the spec sheet also states a thermal resistance of 3.75, so confirm the figure for your thickness before sizing a job. At $105.99 at eBay as of November 4, 2026, it is the best of three new prices.

Questions and answers

Is this sheet worth it over foam insulation?
Rubber closed-cell sheet resists moisture and stays flexible in cold, which foam board does not. If you need a peel-and-stick wrap for ducts or pipes, it is a reasonable buy at $105.99.
What R-value does it actually have?
The listing shows both 1.85 and 3.75. R-value depends on thickness, so check the thickness on the roll you receive before calculating coverage.
Can it be used outdoors?
The rubber itself handles -40 °F to 200 °F, but the adhesive and surface need protection. Jacket or coat it for outdoor and UV-exposed runs.
What temperature range does it cover?
It is rated from -40 °F to 200 °F, with 200 °F as the maximum service temperature. That covers chilled water, refrigeration and most HVAC ductwork.
When is the price lowest?
The best new price seen is $105.99 at eBay as of November 4, 2026, across three stores. Compare per-foot cost, since roll length and thickness drive the real price.
