The VALUE COLLECTION 4HP3/4 is a 3/4-inch hex plug designed to close off open pipe ends in threaded piping systems. Manufactured from 304 stainless steel, it offers solid corrosion resistance in both wet and dry service environments. The male NPT (MNPT) threaded connection engages standard tapered pipe threads for a secure, leak-resistant seal. Rated to 150 psi, this plug suits a wide range of low- to medium-pressure plumbing, HVAC, and industrial piping applications. Licensed plumbers and pipefitters install this type of fitting during system commissioning, pressure testing, or any time a pipe branch needs to be capped off cleanly.
This hex plug is a standard choice for capping unused ports, test points, and branch outlets in residential and light commercial piping systems. Its 3/4-inch MNPT thread size fits common piping found in domestic water supply, HVAC hydronic systems, and general-purpose industrial lines. The hex head allows for wrench engagement with a standard open-end or adjustable wrench, making installation straightforward in tight spaces.
Designed as a standard MNPT threaded hex plug for use with 3/4-inch NPT-threaded pipe fittings and components in plumbing, HVAC hydronic, and general industrial piping systems.
Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC and local plumbing code requirements. Shut off system pressure and drain the line before installing or removing any threaded plug. Apply an appropriate thread sealant or PTFE tape to the MNPT threads before installation. Do not over-tighten; use the wrench flats to apply controlled torque without stressing the fitting body.
