Thickened copper tube thickness: Made of high-quality copper tube with flame-retardant insulation layer, it can withstand high pressure and high temperature. Very suitable for air conditioning circuit groups and air conditioning duct applications
High and low pressure dual pipe: including 1/4 "high pressure pipe and 3/8" low pressure pipe, suitable for split air conditioning and heat pump systems.
Thickened insulation cotton: The extension pipe of the air conditioning copper pipe is made of thickened insulation cotton, which better reduces damage to the internal copper pipe.
Working temperature: This insulated circuit group can operate within a wide temperature range of -40 ° F to 248 ° F. It is suitable for most small split air conditioning units that use refrigerants such as R410A and R32.
Seamless copper tube: pure copper, no fluorine will leak. Crack resistant nuts and flared ends: equipped with crack resistant thickened nuts. Precision flared end without burrs. Composed of embossed polyethylene film and insulation cotton. Sunscreen, fire-resistant, and flame-retardant. Suitable for welding copper fittings and pipes for air conditioning systems, very suitable for HVAC copper wires.
