Aeroflex 502-ac1210 Epdm Pipe Insulation 1/2 in Id 6 Ft

Product Description

The AEROFLEX 502-ac1210 is a closed-cell EPDM foam rubber pipe insulation tube designed to thermally protect straight runs of copper and stainless steel pipe or tubing. Manufactured as an unslit tube with a 1/2 inch inside diameter and 1 inch wall thickness, it delivers an R-value of 4.08 and a K-value of 0.25 BTU. The 6 ft factory-cut length arrives preformed and ready to slide over pipe ends during new installations, reducing field fabrication time. Licensed plumbers, HVAC technicians, and mechanical insulation contractors install this product on refrigerant lines, chilled water piping, and domestic cold water systems.

This insulation tube is suited for residential and light commercial mechanical systems where thermal efficiency and condensation control are priorities. The unslit design maintains a continuous vapor barrier along the pipe length without requiring a separate vapor barrier material. Its operating range spans -297 degrees F to 300 degrees F, making it appropriate for both cryogenic and elevated-temperature service lines. The flexible EPDM construction conforms to piping layouts without cracking or delaminating during installation.

Key Features

• Closed-cell EPDM foam construction requires no separate vapor barrier
• R-value of 4.08 with 1 inch wall thickness for effective thermal insulation
• Unslit tube format preserves insulation integrity along the full pipe length
• Rated for service from -297 degrees F to 300 degrees F
• Plenum rated with a Flame Spread Index of 20 and Smoke Developed Index of 50
• Non-corrosive to copper and stainless steel; UV-resistant and paintable

Compatibility

Sized for 1/4 inch nominal pipe (1/2 inch copper tube size) with a 1/2 inch inside diameter. Suitable for copper and stainless steel pipe and tubing applications in mechanical insulation work.

Installation Notes

Mechanical insulation contractors and licensed HVAC or plumbing technicians typically install pipe insulation in accordance with local mechanical codes and ASHRAE energy standards. For unslit tubes, slide the insulation over the pipe end before final connections are made. Use a compatible contact adhesive at all butt joints and seams to maintain a continuous thermal and vapor seal. Shut off and depressurize the system before working on any open pipe sections.
