Merit Brass XNL103A-16 Brass 45 Street Elbow 1 in

Product Description

The MERIT BRASS XNL103A-16 is a brass 45-degree street elbow designed for threaded pipe systems requiring a directional change at a 45-degree angle. Rated at 125 psi and Class 125, this fitting connects female NPT to male NPT ends, allowing it to thread directly into another fitting without a coupling. It meets lead-free requirements, making it suitable for potable water and plumbing applications where lead content compliance is mandated. The fitting is sized at 1 inch and weighs 0.52 pounds. Licensed plumbers and pipefitters install this type of elbow in water supply, hydronic, and general piping systems.

This street elbow is used in residential and light commercial plumbing systems where space constraints or layout requirements call for a 45-degree offset in a threaded pipe run. The FNPT x MNPT configuration allows the male end to engage directly into a tee, coupling, or valve without an additional fitting in between, reducing overall assembly length. Typical applications include water supply lines, hydronic heating piping, compressed air lines, and general-purpose brass piping work within the Class 125 pressure range.

Key Features

• 45-degree street elbow configuration with FNPT x MNPT connections for compact inline installation
• Class 125 pressure rating at 125 psi for standard water and fluid service
• Lead-free brass construction for compliance with potable water regulations
• 1-inch fitting size for common residential and commercial pipe runs
• Threaded ends for tool-only installation without soldering or press tools

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch threaded brass pipe systems rated at Class 125 or lower pressure service.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter using standard pipe wrenches and thread sealant or PTFE tape applied to the male threads. Always shut off the water supply and depressurize the line before removing or installing threaded fittings. Do not overtighten brass threaded fittings, as brass is softer than iron and can be damaged by excessive torque. Local plumbing codes, including the IPC, may govern fitting material and pressure ratings for specific applications.
