Introducing K‑Flex 0.75‑in. Flexible Rubber Pipe Insulation – 72‑in. Self‑Sealing Sleeve. This durable black rubber sheath measures 0.75 in. in diameter and stretches 72 in. long, delivering a tight, leak‑proof fit around residential and commercial piping. Engineered from high‑grade flexible rubber, it resists crushing, abrasion, and extreme temperatures while maintaining a sleek, low‑profile look. The built‑in self‑sealing edge eliminates the need for extra tape or adhesives, speeding up installation and ensuring a continuous thermal barrier.

Why choose this insulation: The thick 0.5 in. wall provides an R‑value of 3.2, reducing heat loss and helping lower utility bills. Its flexibility lets you maneuver around bends and fittings without tearing, while the semi‑slit design allows a snug, airtight seal that blocks drafts and condensation. Ideal for hot water, steam, or chilled lines, it keeps fluids at stable temperatures and protects surfaces from temperature‑related damage.

Key Features & Benefits:
  • Self‑sealing semi‑slit construction: Creates an instant airtight wrap, perfect for quick, mess‑free installations.
  • High R‑value of 3.2: Provides superior thermal resistance for energy‑efficient homes and businesses.
  • Broad temperature range –300 °F to 300 °F: Performs reliably in freezing winters and scorching summer pipelines.
  • Flexible 0.5 in. wall thickness: Easy to bend around elbows and joints while preserving insulation integrity.
  • Durable black rubber material: Resists moisture, chemicals, and UV exposure for long‑lasting protection.

Wrap up your project with confidence: K‑Flex’s 72‑inch rubber pipe insulation offers a seamless blend of durability, thermal performance, and installation ease. Whether upgrading an HVAC system, protecting water lines, or insulating steam conduits, this product delivers consistent results that save energy and extend pipe life. Choose K‑Flex for a reliable, cost‑effective solution that meets demanding temperature extremes and code requirements.
