Merit Brass X110-04 Brass Pipe Cross 1/4 in Fnpt Class 125

Product Description

The MERIT BRASS X110-04 is a Class 125 brass pipe cross fitting designed for threaded pipe systems requiring a four-way branch connection. It features four female National Pipe Taper (FNPT) threaded ends in a cross configuration, allowing fluid or gas flow to be distributed or joined at a single junction point. Rated at 125 psi, this fitting is suited for low-to-moderate pressure applications in plumbing, HVAC, and general industrial piping. The fitting weighs 0.17 pounds, making it a compact, lightweight component. It is installed by licensed plumbers and pipefitters working on threaded pipe assemblies.

This cross fitting is used in residential and light commercial piping systems where a four-way tee configuration is required. Typical applications include water distribution, low-pressure air lines, and hydronic heating branch connections. The all-FNPT end connections allow direct engagement with standard male NPT threaded pipe or nipples without adapters. It is commonly installed in tight mechanical spaces where a compact brass cross fitting is specified.

Key Features

• Four-way FNPT threaded connections for straightforward inline branch installations
• Class 125 pressure rating at 125 psi for low-to-moderate pressure service
• Brass construction provides corrosion resistance in water and air service
• Compact and lightweight at 0.17 pounds
• Conforms to FNPT thread standard for compatibility with standard NPT male pipe ends

Compatibility

Designed as an OEM-style replacement or new-installation cross fitting for threaded pipe systems using standard 1/4 inch male NPT pipe ends and fittings rated for Class 125 service.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off and depressurize the pipe system completely before removing or installing threaded fittings. Apply an approved thread sealant tape or compound to the male NPT threads before engagement. Do not overtighten, as brass fittings can crack under excessive torque; hand-tighten and then apply only the additional turns necessary to achieve a leak-free seal per IPC guidelines.
