1-1/2" Copper Tube Size (1-5/8"OD) x 72" x 1/2" Wall Pre-Slit Pre-Glued Tubular Insulation, Foam Cover

K-Flex 7PXL048158 – 1-5/8" OD x 1/2" Wall Pre-Slit, Pre-Glued Pipe Insulation, 6' Length

The K-Flex 7PXL048158 is a closed-cell, flexible elastomeric foam insulation designed for use on 1-1/2" copper tube size (CTS) piping. Featuring a 1/2" wall thickness and a pre-slit, pre-glued seam, this 6-foot section offers quick installation and dependable thermal protection for mechanical systems requiring consistent temperature control and moisture resistance.

This product is suited for chilled water, refrigeration, and hot water lines in commercial, industrial, and residential applications. The factory-applied adhesive seam provides a secure bond without additional on-site adhesive, ensuring both speed and reliability during installation.

Key Features

• Pre-Glued Seam – Factory-applied adhesive allows fast closure and reduces the need for field-applied bonding agents.
• Pre-Slit Configuration – Simplifies application on existing piping, minimizing labor time on the job site.
• Closed-Cell Elastomeric Construction – Delivers excellent thermal insulation while resisting condensation and moisture intrusion.
• 1/2" Wall Thickness – Standard for many plumbing and HVAC applications requiring R-value performance and mechanical resilience.
• Domestic Manufacturing – Made in the USA to support product consistency and code compliance.

Technical Specifications

• Nominal Pipe Size: 1-1/2 inch CTS
• Inside Diameter: 1-1/2 inch
• Outside Diameter: 1-5/8 inch
• Wall Thickness: 1/2 inch
• Length: 6 feet
• Material: Closed-cell elastomeric foam

Installation Overview

Ensure all piping is clean and dry prior to insulation. Position the pre-slit tubing around the pipe and press the adhesive seam together to form a continuous seal. If additional sealing or mechanical fasteners are required by code or site conditions, apply them as necessary. The product can be field-trimmed to length using a utility knife.

Application Guidance for Professionals

K-Flex 7PXL048158 is engineered for mechanical system insulation where temperature control, condensation resistance, and labor efficiency are priorities. It is suitable for both new construction and retrofit projects and aligns with common industry practices for thermal insulation on hot and cold water piping systems.
