Merit Brass SW3402D-02 45 Deg Elbow 1/8 in 304 Ss Socket Weld

Product Description

The MERIT BRASS SW3402D-02 is a 45-degree pipe elbow fitting made from 304 stainless steel, designed for socket weld end connections. Rated at 3,000 psi, this Class 3000 fitting is built for high-pressure piping applications where corrosion resistance and structural integrity are required. At 1/8 inch fitting size, it is suited for small-bore instrumentation and process lines. Plumbers, pipefitters, and industrial maintenance technicians install this type of fitting in systems where directional changes in small-diameter pipe runs are needed under demanding pressure and chemical exposure conditions.

This fitting is appropriate for residential and commercial high-pressure piping systems, as well as industrial process and instrumentation lines. The socket weld configuration makes it a common choice in applications where threaded connections are not suitable and a full-penetration welded joint is preferred for pressure integrity. Typical install scenarios include hydraulic lines, chemical process piping, and compressed gas distribution where 304 stainless steel provides adequate corrosion resistance.

Key Features

• 45-degree elbow geometry for moderate directional changes in pipe runs
• 304 stainless steel construction for corrosion resistance in process and industrial environments
• 3,000 psi pressure rating suitable for high-pressure small-bore applications
• Socket weld by socket weld end connections for full-penetration welded joints
• 1/8 inch fitting size for small-bore instrumentation and process lines

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/8 inch socket weld pipe systems rated to Class 3000 pressure service.

Installation Notes

Installation requires a qualified pipefitter or welder familiar with socket weld procedures per ASME B16.11 or applicable codes. Depressurize and drain the system completely before cutting into any existing pipe run. A gap of approximately one pipe wall thickness should be maintained between the pipe end and the socket bottom before welding to allow for thermal expansion — consult applicable welding codes for specific joint preparation requirements. Do not use this fitting in systems where the operating conditions exceed the rated pressure or are incompatible with 304 stainless steel.
