K-flex P809-T11834 Lineset Insulation 1.125in Wall 0.75in Id

Product Description

The K-FLEX P809-T11834 is a closed-cell elastomeric tube insulation designed for refrigerant lineset applications in HVAC systems. With a 1.125-inch wall thickness and a 0.75-inch inner diameter, this product delivers substantial thermal protection around suction and liquid lines. The UV-rated outer surface makes it suitable for outdoor installations where prolonged sun exposure would degrade standard insulation. HVAC technicians and refrigeration mechanics install this product during new equipment commissioning and lineset replacement work.

This insulation is used on residential and light commercial split-system linesets, mini-split refrigerant lines, and other refrigerant piping routed along exterior walls or rooftops. The 6-foot length is practical for shorter runs or for cutting into segments to fit specific sections of a lineset. Its UV-rated construction makes it a common choice wherever lineset piping is exposed to direct sunlight without additional cladding or conduit protection.

Key Features

• 1.125-inch wall thickness provides high thermal resistance to minimize heat gain on suction lines
• 0.75-inch inner diameter sized for common residential lineset tubing
• UV-rated outer surface resists solar degradation for outdoor lineset runs
• 6-foot length suits short runs or segmented fitting around obstacles
• Closed-cell elastomeric construction limits moisture vapor transmission

Compatibility

Designed as an OEM-style replacement or new-installation insulation sleeve for residential and light commercial HVAC refrigerant linesets with a 0.75-inch outer diameter copper tube.

Installation Notes

Installation is typically performed by a licensed HVAC technician or refrigeration mechanic. Power down the system and recover or isolate refrigerant per EPA Section 608 requirements before working on any open refrigerant lines. Slide the insulation over the lineset before brazed fittings are made where possible, or slit and glue the insulation around existing lines using a compatible elastomeric adhesive. Secure all seams and butt joints fully to prevent moisture infiltration and thermal bridging.
