Value Collection PC122NB-4 Brass Hex Plug 1/4 in Mnpt Fnpt

Product Description

The VALUE COLLECTION PC122NB-4 is a brass hex plug fitting designed to seal pipe ends in pressurized fluid and gas systems. It features a 1/4 inch MNPT external thread on one end and an FNPT internal thread on the other, allowing it to cap off or close a threaded port in a pipeline or manifold. Rated to 1,000 psi, the fitting is machined from brass and finished with a nickel plating for added corrosion resistance. Licensed plumbers and HVAC technicians typically install this fitting when blanking off unused ports on valves, tee fittings, manifolds, or service connections.

This hex plug fits into standard 1/4 inch NPT threaded applications found in residential and light commercial plumbing, HVAC refrigerant lines, compressed air systems, and hydraulic assemblies. Its hex head profile accepts a wrench for secure tightening without overtorque. The nickel plated finish helps resist oxidation in damp or corrosive environments, making it suitable for mechanical rooms, utility spaces, and outdoor enclosures where bare brass may degrade.

Key Features

• 1/4 inch MNPT x FNPT thread configuration for standard NPT pipe connections
• 1,000 psi pressure rating suitable for a wide range of plumbing and HVAC applications
• Nickel plated finish over brass base for improved corrosion resistance
• Hex head design allows wrench engagement for controlled installation torque
• Compact, lightweight fitting at 0.02 pounds for easy handling on the job

Compatibility

Designed as a standard replacement or new-installation hex plug for any 1/4 inch NPT threaded port in plumbing, HVAC, compressed air, or light hydraulic piping systems.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off the supply line and relieve system pressure completely before installing or removing any pipe fitting. Apply thread sealant tape or pipe dope to the MNPT threads before engagement, following IPC and IFGC guidelines for the specific media being carried. Hand-tighten first, then use a wrench on the hex head to achieve a leak-free seal without cracking the fitting body.
