Sunbelt Marketing kflex-titan-11812 Pipe Insulation 1-1/8 in

Product Description

The SUNBELT MARKETING kflex-titan-11812 is a UV-resistant, closed-cell elastomeric foam pipe insulation sleeve designed for thermal protection of mechanical piping systems. With a nominal inside diameter of 1-1/8 inches, a wall thickness of 1/2 inch, and a 6-foot length per section, this insulation delivers an R-value of 3.1. The closed-cell foam structure resists moisture absorption and vapor intrusion, making it suitable for both chilled water and refrigerant suction line applications. HVAC technicians, pipefitters, and plumbers install this product on exposed or concealed piping where energy efficiency and condensation control are required.

This insulation is intended for use on copper, steel, or plastic pipe with a nominal outside diameter matching the 1-1/8-inch ID. Typical applications include residential and light commercial HVAC refrigerant lines, chilled water piping, domestic cold water lines, and similar mechanical systems where thermal loss and surface condensation must be controlled. The UV-resistant outer surface makes it appropriate for outdoor or exposed installations without requiring an additional protective jacket.

Key Features

• UV-resistant outer surface suitable for exposed outdoor piping runs
• Closed-cell elastomeric foam construction resists moisture and vapor transmission
• 1/2-inch wall thickness provides an R-value of 3.1
• 1-1/8-inch nominal inside diameter fits standard pipe sizes
• 6-foot section length reduces seam count during installation

Compatibility

Designed as an OEM-style replacement and standard-fit insulation sleeve for mechanical piping with a nominal outside diameter corresponding to a 1-1/8-inch ID fitting, including common copper and plastic pipe used in HVAC and plumbing systems.

Installation Notes

Installation is typically performed by licensed HVAC technicians or pipefitters. Depressurize and dry the pipe surface before applying insulation to ensure proper adhesion at seams and end joints. Use a compatible elastomeric foam adhesive at all longitudinal slits and butt joints to maintain a continuous vapor barrier. Follow local mechanical codes and manufacturer seaming guidelines; avoid stretching the foam during installation, as this reduces effective wall thickness and R-value performance.
