Value Collection PC133NB-8 Brass Countersunk Plug 1/2 in

Product Description

The VALUE COLLECTION PC133NB-8 is a countersunk pipe plug designed for closing off pipe threads in pressurized plumbing and fluid systems. Constructed from brass with a nickel-plated finish, it features a male NPT (MNPT) external thread that engages a female NPT (FNPT) port, and a countersunk (flush-style) head profile that sits below or flush with the surrounding surface. Rated to 125 psi, this plug is suited for low- to medium-pressure water, air, and compatible fluid applications. Plumbers, pipefitters, and maintenance technicians use it to seal unused ports on valves, manifolds, fittings, and equipment housings.

This countersunk plug is used in residential and light commercial plumbing, HVAC equipment, compressed air distribution, and general fluid-handling systems where a low-profile or recessed port closure is required. The 1/2 inch fitting size is one of the most common thread sizes across pipe systems, making this plug a standard bench stock item for service vans and shops. The nickel-plated finish provides added corrosion resistance over bare brass in wet or humid environments.

Key Features

• Countersunk head profile for flush or recessed installation in tight spaces
• Brass base material offers good corrosion resistance and machinability
• Nickel-plated finish provides additional protection in wet or humid environments
• 1/2 inch MNPT x FNPT thread configuration for standard NPT port sealing
• 125 psi pressure rating suitable for low- to medium-pressure service

Compatibility

Designed as a standard 1/2 inch MNPT countersunk plug for use in any FNPT-threaded port or fitting accepting NPT pipe threads at or below 125 psi.

Installation Notes

Installation is performed by plumbers or pipefitters working on pressurized pipe systems. Depressurize and drain the system before removing or installing any pipe plugs. Apply appropriate thread sealant tape or compound to the MNPT threads before installation to ensure a leak-free seal. Follow applicable IPC or local plumbing code requirements for pipe thread assembly and pressure testing.
