Value Collection 4HP1/4 Pipe Hex Plug 1/4 in Mnpt 304 Ss

Product Description

The VALUE COLLECTION 4HP1/4 is a 1/4-inch male NPT hex plug machined from 304 stainless steel. Hex plugs are used to seal open pipe ends and unused threaded ports in fluid and gas piping systems. The external hex head allows standard wrench installation without requiring a driver slot, making seating consistent and repeatable. The 304 stainless steel construction resists corrosion in wet, chemical, and moderate high-temperature environments. This fitting is a standard item for plumbing, HVAC, and industrial piping work where a reliable, corrosion-resistant pipe closure is needed.

This hex plug is suited for residential and commercial plumbing, hydronic heating systems, compressed air lines, and general industrial piping. Plumbers, pipefitters, and HVAC technicians use MNPT hex plugs to cap unused branch outlets, test ports, and gauge connections during system installation, modification, or pressure testing. The 1/4-inch size is common on smaller branch lines, instrument ports, and equipment tappings throughout trade work.

Key Features

• 304 stainless steel construction resists corrosion and oxidation in wet and chemical-exposure environments
• 1/4-inch MNPT thread seals to standard female NPT ports without adapters
• External hex head accepts open-end or adjustable wrenches for consistent torque application
• Compact plug geometry fits tight spaces around equipment tappings and manifold ports
• Suitable for use in plumbing, HVAC, compressed air, and light industrial piping systems

Compatibility

Designed as a standard MNPT hex plug for use in any 1/4-inch female NPT threaded port in plumbing, HVAC, and industrial piping applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or IFGC codes depending on the service. Shut down and depressurize the system and verify zero pressure before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before installation. Do not overtighten stainless steel fittings into dissimilar metal ports, as galling can occur.
