Merit Brass SW3480D-0602 Pipe Insert 3/8x1/8 Ss 3000 Psi

Product Description

The MERIT BRASS SW3480D-0602 is a socket weld pipe insert fitting designed for use in high-pressure piping systems. Constructed from 304 stainless steel, this insert reinforces the pipe end at the joint and is rated to 3,000 psi. The socket weld x socket weld end connection provides a clean, strong joint when welded in place. At 0.12 pounds, it is a compact, lightweight component suited for plumbing, industrial process piping, and mechanical systems. Licensed plumbers and pipefitters install this type of fitting where code and system design call for socket weld connections in stainless applications.

This fitting is appropriate for residential and commercial piping installations where 304 stainless steel is specified for corrosion resistance. The 3/8 x 1/8 inch sizing makes it a common choice for reducing insert applications in moderate to high-pressure lines. It is typically used in process systems, HVAC hydronic loops, and plumbing runs where socket weld joints are required and long-term material integrity is a priority.

Key Features

• 304 stainless steel construction provides corrosion resistance in wet and process environments
• Rated to 3,000 psi for use in high-pressure piping systems
• Socket weld x socket weld end connections for strong, permanent joints
• 3/8 x 1/8 inch fitting size for reducing insert applications
• Lightweight at 0.12 pounds, easy to handle during installation

Compatibility

Designed as an OEM-style replacement or new-installation insert fitting for socket weld piping systems requiring 3/8 x 1/8 inch stainless steel components rated to 3,000 psi.

Installation Notes

Installation should be performed by a licensed plumber or certified pipefitter in accordance with applicable codes such as the IPC and ASME B16.11 socket weld fitting standards. Shut off and depressurize the system completely before fitting removal or installation. Socket weld fittings require proper fit-up and certified welding procedures — do not attempt to tighten or seal without completing the weld. Inspect the fitting and pipe end for burrs or damage before assembly.
