Norgren 124GA2828 Air Flow Check Valve 1/4 Nptf Brass

Product Description

The NORGREN 124GA2828 is a brass air flow check valve designed to control directional flow in compressed air and pneumatic systems. Built with 1/4-inch male NPTF and 1/4-inch female NPTF threaded connections, this valve prevents backflow and maintains system pressure integrity. The all-brass body offers reliable corrosion resistance in industrial and commercial pneumatic applications. Licensed HVAC technicians, pneumatic system installers, and industrial maintenance professionals typically install this type of valve in air lines where unidirectional flow control is required.

This check valve is suited for compressed air distribution lines, pneumatic control circuits, and fluid power systems requiring NPTF threaded connections. Its compact brass construction makes it a practical choice for tight plumbing configurations in both new installations and retrofit projects. The NPTF thread form creates a pressure-tight seal without relying solely on thread sealant, reducing the risk of leaks in pressurized air applications.

Key Features

• Brass body construction for corrosion resistance in compressed air service
• 1/4-inch male NPTF inlet and 1/4-inch female NPTF outlet connections
• NPTF thread form provides a dry-seal mechanical connection
• Check valve configuration prevents reverse flow and protects upstream components
• Compact and lightweight at 0.2 pounds for installation in space-constrained locations

Compatibility

Designed as an OEM-style replacement or new-installation check valve for pneumatic and compressed air systems using 1/4-inch NPTF threaded connections.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic or fluid power systems. Depressurize and lock out the air supply before removing or installing this valve. NPTF threads are designed for dry-seal connections, but applying an appropriate thread sealant is common practice to ensure leak-free joints. Verify flow direction markings on the valve body before final assembly to ensure correct orientation in the air line.
