Parker tg.lsin143812015-fn Preinsulated Copper Line Set 15 Ft

Product Description

The PARKER tg.lsin143812015-fn is a TwinGel preinsulated copper line set designed for refrigerant line connections in air conditioning and heat pump systems. The set includes 1/4-inch and 3/8-inch copper lines bundled together, each pre-wrapped with 1/2-inch UL Verified polyethylene insulation rated for 3-year anti-UV performance. The copper tubing meets ASTM B280 standards and carries UL Certification. At 15 feet in length, it ships with flare nuts included. This line set is installed by licensed HVAC technicians during equipment commissioning or line set replacement. The R-Value 4.0 insulation supports energy efficiency across the refrigerant circuit.

This line set is suited for residential and light commercial air conditioning applications including unitary split systems, ductless mini-splits, VRF systems, and heat pumps. The 15-foot length fits short-run installations common in residential settings. The liquid and suction lines are machinery attached, keeping the bundle aligned during routing. All rolls are marked by the foot to support accurate refrigerant charging calculations and reduce waste on the job.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with refrigerant line set best practices and local mechanical codes. Recover any refrigerant and isolate the system before disconnecting existing line sets. Avoid sharp bends that could kink the copper tubing or compress the insulation. Secure the line set at appropriate intervals per local code requirements and inspect all flare connections for proper seating before pressurizing the system.
