Coliter ® Equal Brass Tee, PN16, 0–120°C, BSP Threaded
GJ3010 Equal Brass Tee – For Hot and Cold Water Branching
The Coliter® GJ3010 Equal Brass Tee is a high-quality forged brass fitting designed for reliable branching in residential and commercial plumbing systems. Featuring three equal-diameter ports (e.g., 20×20×20 mm), it allows seamless connection of hot or cold water lines at a 90-degree junction. Rated for a nominal pressure of PN16 (1.6 MPa) and suitable for operating temperatures from 0°C to 120°C, it is ideal for potable water, heating circuits, and HVAC applications. The fitting uses ISO 228 (BSP) parallel threads for secure, leak-free assembly and is manufactured from lead-free brass with excellent corrosion resistance. Its robust design ensures long-term durability in concealed or exposed installations.
