The Primaflow Gas Meter Union is a specialized plumbing component designed for professional gas engineers tasked with securing pipework connections. Its primary benefit is providing a robust, leak-resistant junction between 22mm piping and 1-inch BSP-threaded gas meter outlets. While it offers excellent structural integrity for both new installations and system repairs, it is strictly intended for use by qualified Gas Safe registered engineers due to the inherent risks associated with gas line maintenance.

Confirm you are measuring the BSP thread correctly; remember that 1-inch BSP threads have an actual physical diameter of 1 1/4 inches.
To install, ensure the gas supply is isolated at the primary control valve. Verify that the 22mm pipe is clean and free of debris. When tightening the 1-inch BSP side, remember that the nominal 1-inch measurement translates to an actual diameter of 1 1/4 inches; ensure the correct sizing tools are used to avoid stripping the threads. Always use approved pipe sealing compound or tape if specifically recommended by regional gas safety guidelines, and verify the seal with a leak detection spray after pressurization. Routine maintenance involves checking for signs of corrosion or leakage during annual boiler service inspections.
