Coliter ® Reducing Male Elbow, PN16, 0–120°C, BSP Threaded
GJ3009 Reducing Male Elbow – Brass Fitting for Pipe Diameter Transition with External Threads
The Coliter® GJ3009 Reducing Male Elbow is a forged brass 90-degree elbow designed to connect pipes of different diameters while changing flow direction, featuring male ISO 228 (BSP) parallel threads on both ends. Common configurations include 20×G1/2" and 25×G3/4", allowing seamless integration between larger supply lines and smaller fixture inlets. Rated for PN16 (1.6 MPa) and suitable for hot and cold water within a temperature range of 0°C to 120°C, it ensures reliable, leak-free performance in residential and commercial plumbing systems. Its compact design is ideal for tight spaces such as under sinks, behind walls, or in HVAC terminal units where space efficiency and smooth flow transition are critical.
