Merit Brass C110-08 Brass Pipe Cross 1/2 Inch Fnpt Class 125

Product Description

The MERIT BRASS C110-08 is a Class 125 brass pipe cross fitting designed for threaded piping systems. It features four female National Pipe Taper (FNPT) end connections, allowing a single fitting to branch a pipeline in four directions simultaneously. Built from brass, this cross fitting handles the pressures and temperatures common in residential and light commercial plumbing, HVAC hydronic lines, compressed air distribution, and general fluid handling. Licensed plumbers and pipefitters are the primary installers. The Class 125 pressure rating and all-FNPT configuration make it a straightforward choice for low-to-moderate pressure systems where a four-way branch connection is needed.

This fitting is suited for 1/2 inch threaded pipe installations in residential and light commercial settings. Typical applications include water distribution lines, hydronic heating loops, compressed air headers, and similar fluid or gas service systems where a four-way cross junction is required. The all-FNPT thread configuration accepts standard male NPT pipe ends on all four ports, keeping installation consistent with common threaded pipe stock and fittings already on the job.

Key Features

• Four-way cross configuration with all FNPT ends for versatile branch connections
• 1/2 inch fitting size fits standard NPT threaded pipe stock
• Class 125 pressure rating suited for low-to-moderate pressure service
• Brass construction provides corrosion resistance in water, air, and compatible fluid systems
• Threaded connection type requires no special tooling beyond a pipe wrench and thread sealant

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2 inch FNPT threaded pipe systems operating within Class 125 service limits.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local plumbing codes. Shut off and depressurize the piping system fully before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to all male NPT threads before assembly, and tighten with a pipe wrench to a snug, leak-free connection without over-torquing the brass body. Verify system integrity with a pressure test before returning the line to service.
