Brennan 16000 Hex Plug 1/8 Inch Mnpt Steel Pipe Fitting

Product Description

The BRENNAN 16000 is a steel hex plug designed to close off open male NPT pipe ports in industrial piping systems. Sized at 1/8 inch MNPT x MNPT, this fitting threads directly into a female NPT port to seal the line. The hex head allows standard wrench engagement for secure installation and removal. Constructed from steel, it is suited for use in moderate-pressure fluid and gas systems where a reliable threaded plug is required. Plumbers, pipefitters, and HVAC technicians install this type of fitting during system assembly, testing, or when capping unused ports on manifolds, valves, and fittings.

This hex plug is used in residential and light commercial piping applications where 1/8 inch NPT ports need to be closed. Common install scenarios include capping test ports on gas lines, sealing unused taps on water distribution manifolds, and closing off instrumentation ports on HVAC equipment. The MNPT x MNPT configuration means the plug carries external threads on both ends, threading into a female NPT receiving port to complete the seal. Sold in packages of 4.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians in accordance with applicable IFGC and IPC requirements.

Do not overtighten steel fittings into softer alloy or brass female ports.
