K-flex P809-T03434 Lineset Insulation 3/4 in Wall 3/4 in Id

Product Description

The K-FLEX P809-T03434 is a flexible closed-cell foam pipe insulation tube engineered for HVAC lineset applications where UV exposure is a concern. With a 3/4-inch wall thickness and a 3/4-inch inner diameter, each section runs 6 feet in length. The thick wall construction provides meaningful thermal resistance to minimize heat gain on refrigerant suction lines, helping maintain system efficiency. The UV-rated outer surface resists degradation from direct sunlight, making this insulation suitable for outdoor lineset runs without additional jacketing. HVAC technicians and installers use this product on split-system and mini-split refrigerant lines.

This insulation tube is intended for refrigerant lineset applications in both residential and light commercial HVAC installations. It is well suited for outdoor lineset runs exposed to direct sunlight, rooftop installations, and any application where standard insulation foam would break down prematurely due to UV exposure. The 3/4-inch inner diameter accommodates common suction line copper tubing sizes used in split-system air conditioning and heat pump installations. Each 6-foot section is easy to cut to length and fit around existing or new linesets.

Key Features

• UV-rated outer surface resists breakdown from prolonged direct sunlight exposure
• 3/4-inch wall thickness provides substantial thermal insulation for refrigerant suction lines
• 3/4-inch inner diameter fits standard copper suction line tubing used in residential and light commercial systems
• 6-foot length per section allows flexible use on a wide range of lineset run configurations
• Flexible closed-cell foam construction conforms to bends without cracking or splitting

Compatibility

Designed as an OEM-style replacement and new-installation insulation solution for refrigerant linesets requiring UV-resistant foam insulation with a 3/4-inch inner diameter.

Installation Notes

Installation is typically performed by a licensed HVAC technician as part of a split-system or mini-split lineset installation or service call. Shut off and recover refrigerant from the system before working on any lines that require insulation removal or replacement. Slit the tube lengthwise if installing over an existing lineset, and use a compatible foam insulation adhesive or UV-rated tape to seal all seams and joints exposed to the elements. Follow local mechanical codes and manufacturer guidelines for insulation requirements on refrigerant piping.
