K-flex P809-T07834 Lineset Insulation 7/8 in Wall 3/4 in Id

Product Description

The K-FLEX P809-T07834 is a UV-rated flexible foam insulation tube designed to protect refrigerant linesets in HVAC and mini-split installations. The tube features a 7/8 inch wall thickness and a 3/4 inch inner diameter, providing substantial thermal insulation around copper lineset tubing. Each section is 6 feet long. The UV-resistant outer surface makes this product suitable for outdoor exposed runs where sunlight degradation is a concern. HVAC technicians and refrigeration mechanics install this product during new system commissioning or when re-insulating existing linesets that have deteriorated.

This insulation tube is used on refrigerant suction and liquid lines in residential and light commercial split systems and mini-split installations. It is well suited for outdoor lineset runs exposed to direct sunlight, rooftop applications, and exterior wall passages where standard insulation would degrade prematurely. The 6-foot length is practical for short runs and stub-outs, and multiple sections can be used end-to-end for longer lineset spans.

Key Features

• 7/8 inch wall thickness for high thermal performance on suction lines
• 3/4 inch inner diameter sized for standard copper lineset tubing
• UV-rated outer surface rated for outdoor and direct-sunlight exposure
• Flexible foam construction for easy handling and fitting around bends
• 6-foot section length suitable for short runs and stub-outs

Compatibility

Designed as an OEM-style replacement or new-installation insulation sleeve for residential and light commercial refrigerant linesets with a 3/4 inch outer diameter copper suction or liquid line.

Installation Notes

Licensed HVAC technicians typically install lineset insulation during system commissioning or service. Recover refrigerant and isolate the system before replacing insulation on active linesets. Slit the tube lengthwise for retrofit installations over existing piping and seal seams with compatible insulation tape or adhesive. Follow local mechanical codes for outdoor installation requirements, including UV-rated materials for exposed exterior runs.
