Value Collection 4HP1 Hex Plug 1 Inch 304 Ss Mnpt 150 Psi

Product Description

The VALUE COLLECTION 4HP1 is a 1-inch hex plug pipe fitting constructed from 304 stainless steel and designed to seal threaded pipe ends in plumbing and fluid-handling systems. The male NPT (MNPT) threaded connection provides a secure, leak-resistant closure when torqued into a female-threaded port or fitting. Rated to 150 psi, this hex plug handles moderate-pressure service in a wide range of piping applications. The 304 stainless steel construction resists corrosion in water, mild chemical, and general industrial environments. Plumbers, pipefitters, and mechanical contractors use this type of fitting to cap unused branch outlets, test ports, or dead-end runs during installation and service work.

This hex plug is suited for residential and light commercial plumbing, HVAC hydronic systems, and general industrial piping where a 1-inch MNPT closure is required. The hex-head drive profile accepts a standard pipe wrench or open-end wrench for fast installation. It is appropriate for use in water supply, compressed air, and other moderate-pressure fluid systems compatible with 304 stainless steel.

Installation Notes

Installation is performed by licensed plumbers or pipefitters working on threaded piping systems. Isolate and depressurize the system before installing or removing any threaded fitting. Apply thread sealant tape or compound to the male threads in accordance with applicable plumbing codes such as the IPC before tightening. Do not overtighten stainless steel fittings, as galling on the threads can make future removal difficult.
