Coliter ® 6-Way Bridge Fitting – GJ3019, PN16, Brass Manifold Component
GJ3019 6-Way Bridge Fitting – For Manifold Systems in Hot & Cold Water Distribution
The Coliter® GJ3019 6-Way Bridge Fitting is a precision-engineered brass manifold component designed for centralized distribution and individual shut-off control in residential, commercial, and HVAC plumbing systems. It features six full-port outlets with ISO 228 (BSP) parallel threads, enabling leak-free, modular connections to multiple hot or cold water lines—ideal for bathroom groups, underfloor heating manifolds, and multi-point supply networks. Rated at PN16 (1.6 MPa) and suitable for operating temperatures from 0°C to 120°C, the GJ3019 ensures reliable performance under demanding conditions. Made from high-quality dezincification-resistant (DZR) brass, it offers excellent corrosion resistance and long service life. With a compact, symmetrical design and standardized dimensions (e.g., L = 117.5 mm for DN20), it simplifies installation and maintenance while supporting modern plumbing efficiency.
