K-flex P809-T03834 Lineset Insulation 3/8 in Wall 3/4 in Id

Product Description

The K-FLEX P809-T03834 is a closed-cell elastomeric foam insulation tube engineered for HVAC lineset applications where UV exposure is a concern. The tube features a 3/8 inch wall thickness and a 3/4 inch inner diameter, with each section running 6 feet in length. Rated for outdoor UV exposure, this insulation is designed to resist solar degradation without requiring an additional protective wrap. HVAC technicians use it on refrigerant lineset runs that pass through exterior walls or along exterior surfaces where sunlight contact is continuous.

This insulation tube is suited for residential and light commercial split-system air conditioning and heat pump installations. It is applied over copper refrigerant lines during new construction, system changeouts, and lineset repair or replacement jobs. The 3/4 inch ID accommodates standard suction or liquid line tubing sizes common in residential split systems. The 6-foot length works well for shorter exposed runs or as a fill piece within a longer insulated section.

Key Features

• UV-rated outer surface resists solar degradation on exposed outdoor lineset runs
• 3/8 inch wall thickness provides thermal insulation to reduce heat gain and condensation
• 3/4 inch inner diameter fits standard residential refrigerant line tubing
• Closed-cell elastomeric foam construction limits moisture absorption
• 6-foot section length suits shorter runs and patch applications

Compatibility

Designed as an OEM-style replacement and new-installation insulation tube for residential and light commercial HVAC refrigerant linesets with 3/4 inch outer diameter copper tubing.

Installation Notes

Installation is performed by licensed HVAC technicians during lineset placement or replacement. Shut off and recover refrigerant charge before working on any open refrigerant lines. Slide the insulation tube over the line before flaring or brazing fittings, or slit lengthwise and use appropriate contact adhesive at the seam for retrofit applications on existing lines. Follow local mechanical codes for insulation requirements on exposed refrigerant piping.
