Norgren 124GA1818 Check Valve 1/8 Inch Nptf Brass

Product Description

The NORGREN 124GA1818 is a brass check valve designed to control air flow direction in pneumatic and compressed air systems. It features 1/8-inch male and 1/8-inch female NPTF threaded connections, allowing it to pass air in one direction while preventing backflow. The all-brass body provides resistance to corrosion and wear in industrial and commercial service environments. Weighing just 0.11 pounds, it is compact and easy to integrate into tight pneumatic circuit assemblies. Licensed pipefitters, pneumatic system technicians, and industrial maintenance professionals are the primary installers of this type of valve.

This check valve is suited for use in pneumatic control lines, compressed air distribution systems, and fluid power circuits where backflow prevention is required. The NPTF thread form creates a pressure-tight seal on both the male and female ends without relying solely on thread sealant. It is commonly installed inline in air tool supply lines, pneumatic actuator circuits, and compressor outlet plumbing in light industrial and manufacturing settings.

Key Features

• Check valve function prevents reverse air flow in pneumatic circuits
• 1/8-inch NPTF male inlet and 1/8-inch NPTF female outlet for dryseal pressure-tight connections
• Brass body construction for corrosion resistance in compressed air and light fluid applications
• Compact and lightweight at 0.11 pounds for installation in space-constrained assemblies
• Sold individually, compatible with standard 1/8-inch NPTF pneumatic fittings and tubing

Compatibility

Designed as an OEM-style inline check valve for pneumatic and compressed air systems using 1/8-inch NPTF threaded connections.

Installation Notes

Installation should be performed by a qualified pipefitter or pneumatic systems technician. Depressurize and lock out the compressed air supply before removing or installing any inline valve. NPTF threads form a dryseal fit, but applying thread sealant tape rated for compressed air is standard practice to ensure leak-free joints. Verify flow direction markings on the valve body before final assembly to confirm correct orientation in the circuit.
