Merit Brass SW3412D-2406 Pipe Reducer 1-1/2x3/8 Ss 3000psi

Product Description

The MERIT BRASS SW3412D-2406 is a 304 stainless steel socket weld pipe reducer designed to transition between two pipe sizes in high-pressure piping systems. Rated at 3,000 psi, this fitting connects 1-1/2 inch pipe to 3/8 inch pipe using socket weld end connections on both sides. The 304 stainless steel construction provides solid corrosion resistance in demanding industrial and mechanical environments. Licensed plumbers, pipefitters, and mechanical contractors install this type of fitting where a permanent, leak-tight reduction is required and where welded joints are specified by code or engineering design.

This reducer is suited for use in commercial and industrial piping systems where pressure ratings and material traceability are critical. Socket weld fittings of this class are commonly found in process piping, HVAC hydronic systems, and mechanical rooms where high-pressure service demands a reliable, weld-in connection. The 1-1/2 x 3/8 inch size change handles significant diameter transitions within a compact fitting body.

Key Features

• 304 stainless steel construction for corrosion resistance in wet and chemically active environments
• 3,000 psi pressure rating suitable for high-pressure piping applications
• Socket weld x socket weld end connections for full-penetration weld joints
• Reduces from 1-1/2 inches to 3/8 inches in a single fitting
• Compact concentric reducer body minimizes installed length

Compatibility

Designed as an OEM-style socket weld reducer for use in 3,000 psi Class 304 stainless steel piping systems requiring a 1-1/2 x 3/8 inch diameter transition.

Installation Notes

Installation of socket weld fittings must be performed by a qualified pipefitter or licensed plumber in accordance with applicable mechanical codes such as the ASME B31.1 or B31.3 piping standards. Depressurize and drain the line completely before cutting into any existing system. Proper socket depth and weld gap must be maintained per the applicable welding procedure specification. Post-weld inspection may be required depending on system classification and local code authority requirements.
