Value Collection PC133NB-6 Brass Countersunk Plug 3/8 in

Product Description

The VALUE COLLECTION PC133NB-6 is a countersunk pipe plug used to seal threaded pipe openings in plumbing, hydraulic, and pneumatic systems. Constructed from brass with a nickel plated finish, this plug features a 3/8 inch MNPT x FNPT end connection and is rated to 125 psi. The countersunk hex drive design allows for flush or recessed installation using a hex key rather than a wrench on exposed flats. Plumbers, pipefitters, and maintenance technicians install these plugs to close off unused ports, branch lines, or test points in piping assemblies.

This plug is suited for residential and light commercial plumbing, compressed air lines, hydraulic manifolds, and general fluid handling systems where a 3/8 inch NPT port needs to be sealed. The MNPT external thread engages the female port, while the FNPT internal thread allows a secondary connection or test instrument to be tapped in if needed. The nickel plated brass construction resists corrosion in a wide range of media and is compatible with water, oil, and many non-aggressive fluids.

Key Features

• Countersunk hex drive design for flush installation without exposed wrench flats
• 3/8 inch MNPT x FNPT end connections for versatile port sealing and pass-through access
• 125 psi pressure rating suitable for low to moderate pressure systems
• Nickel plated brass construction for corrosion resistance and durability
• Compact, lightweight design at 0.03 pounds for easy handling and stocking

Compatibility

Designed as a standard replacement or stock fitting for any 3/8 inch female NPT threaded port in plumbing, compressed air, hydraulic, or fluid handling piping systems.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the MNPT threads before tightening. Use a correctly sized hex key to drive the countersunk plug; do not overtighten, as brass threads can be damaged by excessive torque.
