Nomaco BST07812 Pipe Insulation 1/2 Inch Wall Black

Product Description

The NOMACO BST07812 is a black, lap-seal pipe insulation product manufactured by Armacell, LLC under the AP/Armaflex line. It features a nominal 1/2-inch wall thickness and is designed to reduce heat gain and condensation on cold and chilled water piping systems. The lap-seal design allows for tool-free, adhesive-free closure during installation, which speeds up the job and helps maintain a continuous thermal barrier. Licensed plumbers, HVAC technicians, and mechanical insulation contractors install this type of product on copper, iron, PVC, and other standard pipe materials in both residential and commercial applications.

This pipe insulation is suited for chilled water lines, refrigerant suction lines, domestic cold water piping, and other mechanical piping that is subject to condensation or heat transfer losses. The black exterior finish is UV-resistant, making it appropriate for exposed indoor and outdoor installations. It is commonly used in mechanical rooms, rooftop equipment, and interior piping runs where a finished appearance and reliable thermal performance are required.

Key Features

• Nominal 1/2-inch wall thickness provides thermal resistance for chilled and cold water piping
• Black lap-seal design enables fast, secure closure without additional adhesive at the seam
• Closed-cell foam construction resists moisture absorption and limits condensation
• Black finish is suitable for exposed indoor and outdoor piping applications
• AP/Armaflex product line from Armacell, LLC, a recognized manufacturer of mechanical pipe insulation

Compatibility

Designed as an OEM-style replacement and new-installation pipe insulation for standard residential and commercial mechanical piping systems requiring closed-cell foam thermal insulation with a 1/2-inch wall.

Installation Notes

This product is typically installed by licensed plumbers, HVAC technicians, or insulation contractors following local mechanical codes and ASHRAE energy requirements. Before installing, ensure the pipe surface is clean, dry, and free of oils or debris to promote proper adhesion at the lap seal. Slit the insulation lengthwise, wrap it around the pipe, and press the lap seal firmly to close. On existing systems, shut off and drain the line before service where required by code or safety protocol.
