Coliter ® F-Shaped Gas Tee, 1.6MPa, -20–60°C, BSP Threaded
QF3130 F-Shaped Gas Tee – Brass 3-Way Fitting for Gas Meter and Appliance Branch Connections
The Coliter® QF3130 F-Shaped Gas Tee is a precision-engineered brass 3-way fitting designed to create a branch connection in natural gas, manufactured gas, and liquefied petroleum gas (LPG) piping systems—commonly used between gas meters and household appliances. Its “F-shaped” configuration features three ports: one inlet and two outlets arranged in a compact tee layout, enabling seamless distribution without shut-off functionality. Constructed from high-quality forged brass, it ensures durability and corrosion resistance in residential and utility gas installations. Rated for a nominal pressure of 1.6 MPa and operating temperatures from -20°C to 60°C, it complies with national gas piping standards. All ports feature ISO 228 (BSP parallel) threads, with standard dimensions for DN15 (G1/2"): M = 30×2 mm, H = 30 mm, A = 55 mm. Ideal for secure, leak-free gas line branching where a passive tee—not a valve—is required.

Introduction to Couplings For Gas Meters
Coliter®’s couplings for gas meters are precision-engineered brass fittings designed for secure, leak-free connections between gas meters and supply lines in residential and utility applications. The series includes the standard GJ3101 brass gas coupling and the enhanced GJ3102 extended anti-theft gas fitting, featuring a tamper-resistant design that prevents unauthorized removal or bypass. Both models are made from high-quality forged brass, comply with national gas piping standards, and support working pressures up to 0.1–0.5 MPa with operating temperatures from -20°C to +60°C. With ISO 228 parallel threads (e.g., G1/2", G3/4"), they ensure reliable sealing, corrosion resistance, and long-term safety—essential for gas utilities, smart metering projects, and regulatory-compliant installations.
