Airex AIX-72C-B E-flex Guard Line Set Cover Black 6 Ft

Product Description

The AIREX AIX-72C-B is a black PVC line set cover designed to protect outdoor refrigeration pipe insulation from UV exposure, weathering, and physical damage. Known as the E-Flex Guard, this 6-foot section fits over 3/4-inch wall thickness insulation covering 5/8-inch or 7/8-inch refrigerant tubing, and also accommodates 1/2-inch wall thickness insulation on 1-1/8-inch tubing. The engineered PVC construction meets Class II vapor retarder requirements and satisfies current building, residential, and energy code mandates that restrict or prohibit adhesive tape on outdoor pipe insulation. HVAC technicians use this product to bring line set installations into code compliance on split-system and mini-split applications.

The AIX-72C-B is intended for outdoor refrigeration piping on residential and light commercial split-system air conditioning and heat pump installations. It addresses mandatory requirements found in updated building and energy codes that no longer permit adhesive tapes as the sole exterior protection method for outdoor pipe insulation. The 6-foot length suits standard line set runs and can be combined with additional sections for longer installations. Installation is straightforward on new construction or retrofit projects where exposed line sets require compliant insulation protection.

Key Features

• Engineered PVC construction is UV and weather resistant for long-term outdoor durability
• Rated as a Class II vapor retarder to satisfy current energy code requirements
• Fits 3/4-inch wall insulation over 5/8-inch and 7/8-inch refrigerant tubing
• Also accommodates 1/2-inch wall insulation over 1-1/8-inch tubing
• 6-foot length per section for flexible line set coverage
• Black color provides a clean finished appearance on outdoor installations

Compatibility

Designed to fit over 3/4-inch wall thickness pipe insulation protecting 5/8-inch or 7/8-inch refrigerant tubing, and over 1/2-inch wall thickness pipe insulation protecting 1-1/8-inch tubing. Suitable for outdoor refrigeration and air conditioning line set applications where code-compliant insulation protection is required.

Installation Notes

Installation is performed by licensed HVAC technicians as part of split-system or mini-split line set work. Shut down the system and relieve any pressure from accessible service ports before working on the line set. Verify local building and energy code requirements for insulation protection prior to installation, as specific mandates vary by jurisdiction. Do not use adhesive tape as the primary exterior insulation protection in jurisdictions that have adopted current energy codes restricting that practice.
