2"Copper Tube Size (2-1/8"OD) x 72" x 1/2" Wall Pre-Slit Pre-Glued Tubular Insulation, Foam Cover

K-Flex 7PXL048218 – 2-1/8" OD x 1/2" Wall Pre-Slit, Pre-Glued Pipe Insulation

The K-Flex 7PXL048218 is a 6-foot section of closed-cell elastomeric pipe insulation designed for use on 2" copper tubing. With a 1/2" wall thickness and an outer diameter of 2-1/8", this insulation provides thermal protection and condensation control for mechanical piping systems in commercial and residential installations.

This pre-slit, pre-glued format simplifies application by allowing fast placement and secure closure without requiring field-applied adhesive. The durable foam construction helps reduce thermal transfer, supporting energy efficiency while minimizing moisture ingress in hot or cold water piping applications.

Key Product Features

• Pre-Glued Seam – Integrated adhesive enables fast installation with consistent sealing.
• Closed-Cell Foam Insulation – Maintains thermal resistance and prevents condensation on piping surfaces.
• 1/2" Wall Thickness – Provides effective insulation without excessive bulk.
• Flexible and Lightweight – Allows easy handling and shaping around piping and fittings.
• Made in the USA – Manufactured domestically to meet industry performance standards.

Installation Information

This insulation is designed for rapid application in field environments. The pre-slit design fits over existing pipe runs, and the pre-glued seam simplifies closure. Use a utility knife for cutting to length. Ensure pipe surfaces are clean and dry before application to maintain insulation integrity and vapor barrier performance. Additional sealing may be used where required.

Application Use

Suitable for hot and cold water, chilled water, and refrigeration piping where condensation control and energy conservation are required. Ideal for mechanical rooms, risers, and above-ceiling pipe runs in both retrofit and new installations.
