Aeroflex AC7834 Pipe Insulation 3/4 in Id R-5.3

Product Description

The AEROFLEX AC7834 is a flexible closed-cell elastomeric pipe insulation designed to limit heat gain and condensation on cold-water and refrigerant piping. With a 3/4-inch inner diameter and a 7/8-inch wall thickness, this insulation sleeve delivers an R-value of 5.3, meeting the thermal performance demands of commercial and residential mechanical systems. HVAC technicians and plumbers use this product to insulate copper, steel, and plastic lines where energy efficiency and moisture control are the primary concerns.

The AC7834 is suited for chilled-water lines, refrigerant suction lines, domestic cold-water piping, and similar low-temperature applications. Its flexible closed-cell structure conforms to bends and fittings without compromising the insulating layer. This product is appropriate for both new construction and retrofit installations in residential and light commercial mechanical systems.

Key Features

• 7/8-inch wall thickness provides R-5.3 thermal resistance for energy-efficient pipe insulation
• 3/4-inch inner diameter fits standard 3/4-inch copper and compatible pipe sizes
• Closed-cell elastomeric construction resists moisture absorption and inhibits condensation
• Flexible material allows installation on straight runs, bends, and fittings
• Suitable for refrigerant suction lines, chilled-water piping, and cold domestic water lines

Compatibility

Designed as an OEM-style replacement and new-installation insulation sleeve for 3/4-inch nominal pipe used in residential and light commercial HVAC, refrigeration, and plumbing systems.

Installation Notes

Installation is typically performed by licensed HVAC technicians or plumbers. Shut down and depressurize the system before cutting and fitting insulation on active refrigerant or chilled-water lines. Slit the sleeve lengthwise, fit over the pipe, and seal the seam and all butt joints with a compatible elastomeric adhesive to maintain thermal and vapor barrier continuity. Follow local mechanical codes and ASHRAE 90.1 requirements for minimum insulation thickness on applicable pipe types.
