The AQUALINE BT-150 is a 1.5-inch threaded brass tee fitting used to split or combine flow in pressurized piping systems. Constructed from brass, this tee provides reliable performance in plumbing, hydronic heating, and light commercial piping applications. The threaded end connections allow for straightforward installation into standard NPT-threaded systems without specialized tooling. At 1.72 pounds, the BT-150 offers solid construction suited for demanding trade environments. Licensed plumbers and pipefitters are the primary installers of this type of fitting.
The BT-150 is well suited for residential and light commercial plumbing systems where a 1.5-inch branch connection is required. Common applications include domestic water distribution, hydronic heating loops, and pool or spa plumbing where threaded brass fittings are specified. Its threaded design makes it compatible with standard pipe and fittings already in use at most job sites.
Designed as an OEM-style replacement or standard-install fitting for 1.5-inch threaded brass piping systems in residential and light commercial plumbing applications.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off and depressurize the water supply before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape to all male threads before assembly to ensure a leak-free connection. Do not overtighten threaded connections, as brass fittings can crack under excessive torque.
