The AQUALINE BT-100 is a 1-inch threaded brass tee fitting used to split or combine flow in pressurized piping systems. Constructed from brass, it accepts threaded pipe connections on all three ports and is suited for water, gas, and hydronic applications. At 0.8 pounds, the fitting is compact and solid. Licensed plumbers, HVAC technicians, and pool and spa installers typically specify threaded brass tees when branching supply lines or adding service takeoffs to existing runs. The NPT-style threading seats with standard pipe dope or PTFE tape for a leak-free joint.
The BT-100 fits residential and light commercial piping installations where a 1-inch branch connection is required. Common applications include domestic water supply branching, hydronic heating distribution manifolds, pool and spa equipment plumbing, and irrigation supply lines. The threaded design allows installation without soldering or specialized tooling, making it practical for service and retrofit work in tight spaces.
Designed as an OEM-style replacement or new-installation fitting for 1-inch threaded piping systems in plumbing, HVAC hydronic, and pool or spa applications.
Installation should be performed by a licensed plumber or qualified technician in accordance with local plumbing codes and the IPC. Shut off the water supply and depressurize the line before cutting in or replacing any fitting. Apply PTFE tape or approved pipe thread sealant to all male threads before assembly and tighten with a pipe wrench to a firm, snug fit. Do not overtighten brass fittings, as the threads can be damaged.
