Anderson Metals 756120-0404 Pipe Adapter Mnpt X Fnpt

Product Description

The ANDERSON METALS 756120-0404 is a male-to-female pipe thread adapter designed for connecting 1/4-18 MNPT to 1/4-18 FNPT fittings in low- and high-pressure piping systems. Rated to 1000 psi maximum working pressure and certified lead free, this adapter is suited for use in potable water, grease, fuel, LP gas, and natural gas service lines. Plumbers, pipefitters, and HVAC technicians install this type of adapter when transitioning between male and female NPT connections on valves, gauges, equipment ports, and distribution manifolds. The compact form factor and standard NPT thread profile allow direct hand-start threading before final wrench tightening.

This adapter is appropriate for residential and light commercial applications where a direction-change or gender-change fitting is needed in a threaded pipe assembly. Typical install scenarios include gas appliance connections, fuel distribution headers, hydraulic lines, and potable water service where lead-free compliance is required by code. Its 1000 psi pressure rating provides margin for higher-pressure fuel and gas service as well as standard plumbing line pressures.

Key Features

• 1/4-18 MNPT x 1/4-18 FNPT thread configuration for direct gender-change connections
• 1000 psi maximum working pressure rating
• Lead free construction — meets lead-free requirements for potable water systems
• Compatible with potable water, grease, fuels, LP gas, and natural gas service
• Standard NPT thread profile for broad compatibility with pipe fittings and equipment ports

Compatibility

Rated for use with potable water, grease, fuels, LP gas, and natural gas systems requiring 1/4-18 NPT threaded connections. Designed as an OEM-style replacement or service fitting for any threaded piping assembly using standard 1/4-18 NPT male and female ports.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or HVAC technician in accordance with applicable IPC, IFGC, or local code requirements. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape to the male threads before assembly and tighten to hand-snug plus wrench-tight per standard NPT practice. Do not over-torque — NPT threads are tapered and will distort or crack fittings if overtightened.
