Nibco 9025400PC Wrot Copper Press X Fnpt Adapter

Product Description

The NIBCO 9025400PC is a wrot copper adapter fitting designed to transition between a press-style connection and a female NPT threaded port. The fitting accepts a 1-inch press end on one side and a 3/4-inch FNPT connection on the other, making it a practical solution for joining press copper systems to threaded pipe, valves, or equipment ports. It is manufactured from wrot copper, which provides reliable pressure ratings and corrosion resistance suited to potable water, hydronic heating, and general plumbing distribution systems. Licensed plumbers and pipefitters install this type of fitting in both new construction and retrofit work.

This adapter is used in residential and light commercial plumbing applications where a press copper distribution system must connect to a threaded fitting, valve body, or mechanical equipment port. The press end eliminates the need for open flame at the connection point, making it well suited for installations near combustibles or in occupied spaces. The FNPT end accepts standard tapered pipe threads with appropriate thread sealant or PTFE tape.

Key Features

• Wrot copper construction for strength and corrosion resistance in water and hydronic systems
• 1-inch press inlet transitions to 3/4-inch FNPT outlet for mixed-system connections
• Press end requires no soldering, open flame, or flux at the joint
• FNPT end compatible with standard tapered NPT threaded fittings and valves
• Domestic manufacture

Compatibility

Designed as an OEM-style press copper adapter for use in residential and commercial press-system plumbing installations requiring a transition from a 1-inch press connection to a 3/4-inch female NPT threaded port.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off water supply and depressurize the line before making any connections. The press end requires a compatible press tool and approved jaw set sized for the pipe diameter. Apply PTFE tape or a listed thread sealant to the FNPT threads before assembly.
