Merit Brass SW3480D-0604 Pipe Insert 3/8x1/4 Ss 3000psi

Product Description

The MERIT BRASS SW3480D-0604 is a socket weld pipe insert fitting manufactured from 304 stainless steel. It transitions between a 3/8-inch and 1/4-inch line using socket weld connections on both ends, and is rated to 3,000 psi. This type of fitting is used to reduce or insert within a piping run where high-pressure integrity and corrosion resistance are required. It is installed by licensed pipefitters and plumbers working on industrial or commercial fluid systems where socket weld construction is specified by design or code.

This fitting is appropriate for high-pressure piping systems in commercial and industrial applications, including process piping, hydraulic lines, and other fluid-handling installations that require stainless steel construction. The socket weld end connections suit situations where a leak-tight, permanent joint is needed at reduced pipe sizes. It is sold individually and is commonly stocked by trade professionals for maintenance and repair work on existing socket weld systems.

Key Features

• 3/8 x 1/4 inch reducing insert configuration for socket weld piping runs
• 304 stainless steel construction for corrosion resistance in wet or chemical environments
• 3,000 psi pressure rating suitable for high-pressure applications
• Socket weld x socket weld end connections for permanent, leak-tight joints
• Sold as a single piece with no minimum order beyond one unit

Compatibility

Designed as an OEM-style replacement or new-install component for 3/8 x 1/4 inch socket weld piping systems requiring a 304 stainless steel insert fitting rated to 3,000 psi.

Installation Notes

Socket weld fittings are installed by qualified pipefitters or licensed plumbers in accordance with applicable codes such as ASME B31.1 or B31.3 for pressure piping systems. Depressurize and drain the line completely before cutting into an existing system. Socket weld joints require proper fit-up, gap spacing per weld procedure, and a qualified welder to complete the connection. Do not apply thread sealant or compression fittings to socket weld ends.
