Parker gbw.un385812025b Insulated Lineset 25 Foot

Product Description

The PARKER gbw.un385812025b is a pre-insulated suction line lineset designed for unitary HVAC systems. It pairs a bare copper coil for the suction line with a pre-insulated liquid line, delivering a complete, ready-to-install solution for residential and light commercial refrigeration and air conditioning work. The lineset measures 25 feet in length and accommodates suction line tubing in the 3/8 to 5/8 inch range with a 1/2 inch insulated liquid line. Licensed HVAC technicians installing split-system equipment will find the integrated design reduces field prep time and material waste on standard linerun installations.

This lineset is suited for unitary split-system air conditioning and heat pump applications using high-pressure refrigerants including R-410A. The 25 foot run covers typical residential and light commercial installations where the air handler and condensing unit are in close proximity. Foot markings printed along the insulation allow the installer to measure refrigerant charge accurately at the time of commissioning, minimizing copper trim waste and charge calculation error in the field.

Key Features

• Outer polyethylene jacket protects closed-cell foam insulation from tearing during pull-through and installation
• Incremental foot markings printed on insulation support accurate initial refrigerant charge calculations and reduce copper waste
• Rated for high-pressure refrigerant applications including R-410A
• UV-resistant construction tested internally for a minimum of 3 years of UV exposure
• Insulation is paintable with a high-quality exterior paint for color-matching in exposed exterior installations
• Pre-insulated liquid line included, reducing field insulation labor on the lineset assembly

Compatibility

Designed as an OEM-style replacement and new-installation lineset for unitary split-system air conditioning and heat pump equipment using high-pressure refrigerants such as R-410A.

Installation Notes

Installation should be performed by a licensed HVAC technician following applicable mechanical codes and EPA Section 608 refrigerant handling requirements. Power down and lock out the condensing unit and air handler before making any line connections. When routing through exposed exterior areas, apply a high-quality exterior paint over the insulation and consider installing under plastic duct for added protection. Completely seal the open ends of the copper pipe when connecting to the AC unit to prevent water or debris from entering the insulation cavity.
