Value Collection 4HP11/4 Hex Pipe Plug 1-1/4 in 304 Ss Mnpt

Product Description

The VALUE COLLECTION 4HP11/4 is a hex pipe plug designed to seal off threaded pipe openings in plumbing, HVAC, and industrial piping systems. Constructed from 304 stainless steel, this plug offers solid corrosion resistance in both wet and mildly corrosive environments. The male NPT (MNPT) threaded connection provides a standard, reliable seal when installed into a female-threaded port or fitting. Rated to 150 psi, the plug is suited for low-to-medium pressure applications. The hex head profile accepts a standard wrench for controlled tightening. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting during system commissioning, pressure testing, or when capping unused ports on manifolds and equipment.

This hex plug is a common component in residential and light commercial plumbing and HVAC piping systems. It is used to permanently or temporarily close off 1-1/4 inch female NPT threaded openings on pipes, valves, tee fittings, and equipment ports. Typical applications include capping test ports, sealing unused manifold connections, and closing off branch lines during staged system construction or service work.

Key Features

• 304 stainless steel construction for corrosion resistance in wet and mildly aggressive environments
• MNPT threaded connection for compatibility with standard female NPT pipe fittings
• 150 psi pressure rating suitable for low-to-medium pressure piping systems
• Hex head design accepts standard wrenches for secure, torque-controlled installation
• 1-1/4 inch fitting size fits common pipe sizes found in plumbing and HVAC branch lines

Compatibility

Designed as an OEM-style replacement or service fitting for any 1-1/4 inch female NPT threaded port in plumbing, HVAC, or light industrial piping systems rated at or below 150 psi.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter following applicable IPC or IFGC code requirements for the system type. Shut down and depressurize the system 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; use a wrench on the hex head and avoid exceeding the fitting and pipe material limits.
