EPOTOOR 50FT Twin Copper Extension Hose 3/8" & 5/8" for Mini Split Air Conditioner - Insulated

Product overview: This EPOTOOR air conditioning extension consists of a 50 ft length of twin copper tubing with diameters of 3/8" and 5/8" (diameter of brass hose: 3/8 inch and 5/8 inch). It includes heat-preservation cotton and brass fittings and is supplied as shown in the picture — without any other accessories. Material and durability: The tubing is made from copper, offering good toughness, hardness and ductility, along with corrosion resistance for an extended service life. Insulation: The hoses are wrapped in thickened insulation cotton to better protect the internal copper lines. Note: the temperature resistance of this insulation layer shall not exceed 80 degrees. Fittings and workmanship: The product uses thickened nuts with high hardness for a secure, slip-resistant connection and long-lasting strength. Mechanical precise reaming ensures there are no burrs and minimizes the risk of leakage, providing a more reliable installation.
