Fairview 121-B Brass Hex Head Plug 1/4 in Male NPT Pipe Fitting

The Fairview 121-B is a brass hex head plug with a 1/4 in male NPT thread. Designed to seal off open pipe ends, this plug is a reliable solution for capping unused ports in fluid and gas systems across plumbing, pneumatic, hydraulic, and general industrial applications.

Key Features:

• Material: Solid brass construction for excellent corrosion resistance and long-term durability
• Thread: 1/4 in Male NPT (National Pipe Taper) for a pressure-tight, leak-free seal
• Drive Style: Hex head design for easy installation and removal with a standard wrench or socket
• Application: Ideal for sealing pipe ends in hydraulic, pneumatic, plumbing, fuel, and air lines
• Compatibility: Works with standard 1/4 in NPT female-threaded fittings, valves, and manifolds

Brass pipe plugs are a trusted industry standard for temporarily or permanently closing off pipe ports. The tapered NPT thread creates a metal-to-metal seal, and the addition of thread sealant tape (PTFE) or pipe dope ensures a leak-free connection under pressure.
