The AQUALINE BU-050 is a 0.5-inch threaded brass union designed for joining and disconnecting sections of pipe in plumbing, pool, and irrigation systems. Threaded unions allow technicians to separate pipe runs without cutting, making them a standard fitting for serviceability in both new construction and retrofit applications. The brass construction provides corrosion resistance suitable for water service lines. At 0.2 pounds, the BU-050 is a compact, lightweight fitting that stores and handles easily on the job site. Licensed plumbers and pool service technicians are the primary installers of this fitting.
The BU-050 is suited for residential and light commercial plumbing systems where a removable threaded connection is needed. Common applications include equipment connections on pool and spa systems, water heater piping, and general plumbing service points where future disconnection is anticipated. The threaded ends allow installation without specialized tools beyond pipe wrenches and thread sealant.
Designed as an OEM-style replacement or new-installation fitting for 0.5-inch threaded pipe connections in residential and light commercial plumbing and pool systems.
Installation should be performed by a licensed plumber or qualified pool service technician in accordance with applicable local plumbing codes and IPC guidelines. Shut off water supply and depressurize the line before beginning work. Apply approved thread sealant or PTFE tape to all male threads before assembly. Do not overtighten threaded connections, as brass fittings can crack under excessive torque.
