Description
This professional-grade inlet stem is a critical replacement component for primary draught regulators, designed to bridge the connection between the high-pressure gas source and the regulator body. Manufactured from high-tensile forged brass with a mirror-chrome finish, this stem provides superior corrosion resistance in the damp, high-CO2 environments typical of draught cellars and walk-in coolers. Its precision-machined threads and bull-nose seating surface ensure a gas-tight seal, preventing hazardous leaks and ensuring consistent pressure delivery to your kegging system.
- Material: Chrome-Plated Forged Brass
- Inlet Connection: Standard 1/4″ NPT Male Thread
- Outlet Interface: Bull-nose design for CGA-320 (CO2) or CGA-580 (Nitrogen) nut compatibility
- Compatibility: Fits most major regulator brands including Micro Matic, Taprite, and Norgren
- Durability: Engineered for high-pressure gas applications up to 3000 PSI
- Finish: High-polish chrome for sanitary maintenance and aesthetics
Technician’s Note: When replacing an inlet stem, always use a high-quality food-grade oxygen-safe thread sealant or PTFE tape on the NPT threads entering the regulator body. Be extremely careful not to over-torque the stem into the regulator, as the forged brass can stress-crack the regulator housing if forced. After installation, always perform a “bubble test” using a specialized leak detector solution at the junction to ensure there are no micro-leaks, which are the leading cause of wasted gas cylinders.
