The HAILIANG 3/445cest is a 3/4-inch OD short-radius street elbow made from copper, formed at a 45-degree angle for directional changes in tight spaces. Street elbows feature one male (spigot) end and one female (socket) end, allowing direct connection to fittings without an additional coupling. This fitting is used in sweat-soldered copper piping systems and is installed by licensed plumbers and HVAC technicians in both new construction and service work.
This fitting is suited for residential and light commercial plumbing, hydronic heating, refrigerant piping, and HVAC condensate or water supply lines where a 45-degree directional change is required. The short-radius design keeps offsets compact, making it a practical choice when working in confined mechanical spaces or tight wall cavities.
Designed as an OEM-style replacement fitting for standard 3/4-inch OD copper tube systems in plumbing and HVAC applications.
Installation is performed by a licensed plumber or HVAC technician following applicable IPC and IFGC guidelines. Shut off and drain the line before cutting or fitting. Clean all mating surfaces with emery cloth and apply lead-free flux before sweating the joint. Do not overheat the fitting, as excessive heat can damage the copper or cause flux to burn off before solder flows properly.
