Value Collection 4HP1/8 Pipe Hex Plug 1/8 in 304 Ss

Product Description

The VALUE COLLECTION 4HP1/8 is a 1/8 inch male NPT hex plug used to seal off open pipe ends in pressurized fluid and gas systems. Machined from 304 stainless steel, it provides corrosion resistance suitable for water, steam, compressed air, and mild chemical service. The hex head accepts a standard wrench for installation and removal, making it a reliable dead-end fitting for a wide range of plumbing, HVAC, and industrial piping applications. At 150 psi pressure rating, it meets typical low-pressure system requirements. Plumbers, pipefitters, and HVAC technicians commonly use this plug to cap unused branch outlets or test ports during system commissioning or maintenance.

This hex plug is suited for residential and light commercial piping systems where a threaded dead-end cap is needed on a 1/8 inch NPT port. Common applications include capping gauge ports, test tees, manifold outlets, and unused branch connections on compressed air headers, hydronic heating lines, and general plumbing assemblies. The 304 stainless steel construction makes it appropriate for mildly corrosive environments where carbon steel plugs would be unsuitable.

Key Features

• 304 stainless steel construction resists corrosion in water, steam, and mild chemical service
• 1/8 inch MNPT thread for direct installation into female NPT fittings and ports
• 150 psi pressure rating suitable for low-pressure plumbing and HVAC applications
• Hex head design allows installation and removal with standard wrenches or sockets
• 5/8 inch length provides adequate thread engagement for a secure, leak-free seal

Compatibility

Designed as a standard 1/8 inch MNPT hex plug for use in any female NPT-threaded fitting, valve body, manifold port, or pipe end requiring a dead-end cap rated to 150 psi.

Installation Notes

Installation is performed by plumbers or pipefitters following applicable IPC or IFGC guidelines depending on the service. Depressurize and drain or isolate the line before installing or removing threaded plugs. Apply PTFE tape or pipe thread sealant to the male threads before installation to ensure a leak-free connection. Do not over-torque stainless steel fittings into dissimilar metal ports, as galling can occur.
