K-flex P809-T05834 Lineset Insulation Tube 5/8 Wall

Product Description

The K-FLEX P809-T05834 is a UV-rated flexible elastomeric tube insulation designed to protect refrigerant linesets from heat gain, condensation, and ultraviolet degradation. Featuring a 5/8-inch wall thickness and a 3/4-inch inner diameter, this TITAN INSUL-TUBE slips over standard lineset tubing and delivers consistent thermal performance in both indoor and outdoor applications. Each section is 6 feet long, making it practical for standard lineset runs and minimizing field cutting. HVAC technicians and refrigeration mechanics install this product as part of split-system and mini-split refrigerant line installations.

This insulation tube is suited for residential and light commercial HVAC applications where lineset protection is required on exposed exterior runs, rooftop installations, or any environment with direct sunlight exposure. The UV-rated outer surface resists solar degradation, making it appropriate for outdoor use without additional jacketing. The 3/4-inch ID accommodates common refrigerant line sizes used in split-system air conditioning and heat pump installations.

Key Features

• 5/8-inch wall thickness for effective thermal insulation on refrigerant lines
• 3/4-inch inner diameter fits standard lineset tubing sizes
• UV-rated construction resists solar degradation on outdoor and exposed installations
• 6-foot length per section suits typical lineset run segments
• Flexible elastomeric material conforms to bends and offsets in the lineset

Compatibility

Designed as an OEM-style replacement and new-installation insulation sleeve for refrigerant linesets in residential and light commercial split-system HVAC and heat pump applications with a 3/4-inch outer-diameter suction or liquid line.

Installation Notes

Installation is typically performed by licensed HVAC technicians during lineset installation or as a retrofit over existing refrigerant lines. Recover or isolate refrigerant and power down the system before working on linesets. Slide the tube over the line before making flare or braze connections where possible, as the closed-cell construction limits post-connection sleeving. Follow local mechanical codes and manufacturer guidelines for sealing seams and securing insulation on outdoor runs.
