Merit Brass SW3680D-0604 Pipe Insert 3/8x1/4 SS316 Sw

Product Description

The MERIT BRASS SW3680D-0604 is a 316 stainless steel pipe insert fitting designed for socket weld connections in high-pressure piping systems. Rated to 3,000 psi, it transitions between a 3/8-inch and 1/4-inch pipe connection using a socket weld by socket weld end configuration. The 316 stainless steel construction provides strong resistance to corrosion, making it appropriate for demanding fluid and gas handling applications. This fitting is typically installed by licensed plumbers and pipefitters working on industrial, commercial, or process piping assemblies where pressure integrity and material compatibility are critical.

This insert fitting is suited for use in process piping, instrumentation lines, hydraulic systems, and similar high-pressure applications where a reduction between 3/8-inch and 1/4-inch socket weld connections is required. Its 316 stainless steel material grade makes it compatible with corrosive media environments including certain chemical, marine, and sanitary service lines. Installation is performed by qualified pipefitters and plumbers working to applicable piping codes and pressure system standards.

Key Features

• 316 stainless steel construction for corrosion resistance in demanding service environments
• 3,000 psi pressure rating suitable for high-pressure piping systems
• Socket weld by socket weld end connections for secure, leak-resistant joints
• 3/8-inch by 1/4-inch sizing provides a compact inline reduction
• Lightweight at 0.19 pounds, minimizing load on small-bore piping assemblies

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/8-inch by 1/4-inch socket weld piping systems requiring 316 stainless steel material and a 3,000 psi pressure rating.

Installation Notes

Installation of socket weld fittings should be performed by a licensed pipefitter or plumber in accordance with applicable piping codes such as ASME B31.1 or B31.3. Depressurize and isolate the piping system completely before beginning any fitting work. Socket weld joints require proper fillet weld preparation and should be inspected per the applicable code after welding. Do not exceed the rated pressure or use this fitting in services for which the material grade is not rated.
