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.
