Armacell IPBST07812 Pipe Insulation 7/8 in Id

Product Description

The ARMACELL IPBST07812 is a closed-cell foam pipe insulation sleeve designed to reduce heat gain and condensation on refrigerant and chilled-water piping systems. With a 7/8 inch inner diameter and a 1/2 inch wall thickness, this product fits standard copper tubing and provides thermal protection in residential and light commercial HVAC and plumbing applications. HVAC technicians and plumbers install this sleeve during new construction or service calls where bare pipe runs require insulation to meet energy codes or prevent moisture damage.

This insulation sleeve is suited for use on suction lines, chilled-water supply and return lines, and domestic cold-water piping where condensation control is a priority. The 7/8 inch ID accommodates standard 3/4 inch copper tube OD, making it a common choice for refrigerant suction line insulation in split-system air conditioning installations. It is installed by slitting the sleeve lengthwise and pressing it over the pipe, then sealing the seam with appropriate foam insulation adhesive.

Key Features

• 7/8 inch inner diameter fits standard 3/4 inch copper tube
• 1/2 inch wall thickness provides thermal and condensation control
• Closed-cell foam construction resists moisture absorption
• Flexible sleeve design allows installation on straight runs and moderate bends
• Suitable for refrigerant suction lines and chilled-water piping

Compatibility

Designed as an OEM-style replacement and standard-fit insulation sleeve for 7/8 inch ID pipe applications in residential and light commercial HVAC and plumbing systems.

Installation Notes

Installation is typically performed by licensed HVAC technicians or plumbers. Shut down the system and allow piping to reach ambient temperature before applying insulation. Slit the sleeve lengthwise, press it over the pipe, and seal all seams and butt joints with compatible foam insulation adhesive to maintain thermal and vapor-barrier integrity. Follow local energy codes and manufacturer adhesive guidelines for outdoor or high-humidity installations.
