Value Collection PC133NB-4 Brass Countersunk Plug 1/4 in

Product Description

The VALUE COLLECTION PC133NB-4 is a countersunk pipe plug manufactured from brass with a nickel-plated finish. It is designed to close off pipe openings in low- to medium-pressure fluid and gas distribution systems. The male NPT external thread seats into a female NPT port, with the countersunk head allowing the plug to sit flush or recessed with the surrounding surface. Rated to 125 psi, this plug suits applications where a clean, low-profile closure is required. Plumbers, pipefitters, and HVAC technicians install this type of fitting during system pressure testing, decommissioning of unused ports, or permanent line termination.

This 1/4-inch countersunk plug is used in residential and light commercial plumbing, hydronic heating systems, compressed air lines, and HVAC refrigerant or condensate piping where an NPT port must be sealed. The nickel plating provides additional corrosion resistance over bare brass, making it suitable for moist or corrosive service environments. The MNPT x FNPT end configuration means the plug threads into any standard female NPT fitting or manifold port of the corresponding size.

Key Features

• Countersunk head profile allows flush or recessed installation in manifolds and flat surfaces
• Brass base material provides good corrosion resistance and machinability
• Nickel-plated finish adds an extra layer of corrosion protection
• 125 psi pressure rating suitable for low- to medium-pressure service
• 1/4-inch MNPT x FNPT thread configuration fits standard NPT ports

Compatibility

Designed as an OEM-style replacement or new-installation pipe plug for any 1/4-inch female NPT port in standard plumbing, HVAC, or compressed air piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing code requirements. Shut off system pressure and depressurize the line completely before removing or installing any pipe plug. Apply an appropriate thread sealant or PTFE tape to the MNPT threads before installation to ensure a leak-free seal. Do not overtighten brass fittings, as the material can be damaged by excessive torque.
