Merit Brass C102-08 Brass Coupling 1/2 in Fnpt Class 125

Product Description

The MERIT BRASS C102-08 is a Class 125 brass pipe coupling with female NPT (FNPT) connections on both ends. It accepts 1/2 inch pipe threads and provides a straight, inline joint between two threaded pipe sections. The fitting is machined from brass, which offers corrosion resistance and reliable sealing in a wide range of fluid and gas service applications. Plumbers, pipefitters, and HVAC technicians use couplings like the C102-08 when extending, repairing, or reconfiguring threaded piping systems. The FNPT x FNPT configuration means both mating pipes are male-threaded, with the coupling serving as the internal female connector.

The C102-08 is suited for residential and light commercial plumbing, hydronic heating, compressed air, and general-purpose gas and water distribution systems where 1/2 inch NPT threaded connections are standard. Its Class 125 pressure rating aligns with typical low- to medium-pressure service conditions found in supply lines, branch connections, and equipment tie-ins. Licensed plumbers and pipefitters install this fitting in applications governed by the IPC and IFGC where brass fittings are the specified material.

Key Features

• 1/2 inch fitting size with FNPT x FNPT end connections for straight inline joining of male-threaded pipe
• Class 125 pressure rating suitable for low- to medium-pressure water, gas, and air service
• Brass construction provides corrosion resistance and long service life in wet and dry piping systems
• Standard NPT thread form ensures broad compatibility with commonly available pipe and fittings
• Compact, single-unit package ready for immediate installation

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2 inch male NPT threaded pipe in Class 125 brass piping systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC or IFGC requirements. Shut off the water or gas supply and depressurize the line before threading the fitting. Apply an approved thread sealant or PTFE tape to the male pipe threads before making up the joint. Do not over-tighten; use a pipe wrench and turn to snug-plus-turns per standard NPT assembly practice without exceeding the fitting's rated pressure class.
