The VALUE COLLECTION C536142 is a male NPT hex plug designed to close off open pipe ends and unused threaded ports in industrial piping systems. The hex head allows for tightening with a standard wrench, creating a secure, pressure-holding seal at the threaded connection. This type of fitting is a staple in plumbing, HVAC, compressed air, and general industrial piping work where a threaded female port must be capped or blanked off. The MNPT thread pattern follows standard NPT taper specifications, making it broadly compatible with iron, steel, and brass threaded fittings of the same nominal size.
This hex plug is suited for maintenance, repair, and installation work across residential and commercial piping systems. It is commonly used by plumbers, pipefitters, and HVAC technicians to seal test ports, unused branch tees, and manifold outlets. The part ships in a package quantity of 25 units, making it practical for contractors who need to keep a working supply of pipe plugs on hand for service calls and new installations.
Designed as a standard MNPT hex plug for use in female NPT-threaded piping ports found in industrial, commercial, and residential pipe systems.
Installation is performed by plumbers, pipefitters, or HVAC technicians working on threaded pipe systems. Depressurize and isolate the relevant pipe section before installing or removing any threaded fitting. Apply thread sealant tape or pipe dope to the male threads before installation to ensure a leak-free seal. Follow applicable codes such as IPC or IFGC for the specific system being serviced.
