The PDM US gbw.un383412025b is a pre-insulated copper refrigerant lineset designed for residential and light commercial HVAC installations. The lineset includes a 3/8 inch liquid line and a 3/4 inch suction line, with 1/2 inch insulation on the suction line to limit heat gain and maintain system efficiency. Rated to 700 psi and tested across a temperature range of -94 to 250 degrees F, this lineset meets the demands of standard split-system air conditioning and heat pump applications. The copper tubing conforms to ASTM B1003, ASTM B280, and ASTM C1427-07. Total length is 25 feet. Installed by licensed HVAC technicians during new equipment commissioning or system changeover.
This lineset is suited for connecting an outdoor condensing unit or heat pump to an indoor air handler or evaporator coil. The 25-foot run length accommodates typical residential installations where the indoor and outdoor units are in close proximity. The black insulation jacket blends with common installation environments and provides UV and thermal protection along the suction line. Domestically sourced, this lineset is appropriate for split-system installations requiring ACR-grade copper tubing that meets recognized industry material standards.
Designed as an OEM-style replacement or new-installation lineset for residential and light commercial split-system air conditioners and heat pumps requiring a 3/8 inch liquid line and 3/4 inch suction line configuration.
Installation should be performed by a licensed HVAC technician. Recover and evacuate the system to the required vacuum level before connecting the lineset, and pressure-test per local mechanical code requirements before charging. Secure the lineset with appropriate hangers to prevent vibration stress on the copper tubing. Do not overbend the lines, as kinking will restrict refrigerant flow and reduce system capacity.
