Merit Brass 3614D-2006 Pipe Bushing 1-1/4x3/8 316SS

Product Description

The MERIT BRASS 3614D-2006 is a stainless steel hex pipe bushing designed to reduce a 1-1/4 inch male NPT fitting down to a 3/8 inch female NPT port. Constructed from 316/316L stainless steel, it delivers a pressure rating of 3,000 psi and resists corrosion in aggressive media, making it well suited for demanding fluid and gas piping systems. At 13/16 inches in length, it is a compact, heavy-duty fitting installed by licensed plumbers, pipefitters, and mechanical contractors wherever a threaded pipe size reduction is required.

This bushing is used in industrial, commercial, and marine piping applications where corrosion resistance and high-pressure performance are critical. Typical installations include process piping, chemical handling lines, saltwater systems, and HVAC hydronic circuits requiring a reliable stainless steel threaded reducer. The MNPT x FNPT end configuration allows direct in-line installation between threaded pipe sections without additional adapters.

Key Features

• 316/316L stainless steel construction for superior corrosion resistance in wet, chemical, and marine environments
• 3,000 psi pressure rating suitable for high-pressure piping systems
• MNPT x FNPT end connections for straightforward threaded installation
• Reduces 1-1/4 inch male NPT to 3/8 inch female NPT in a single fitting
• Compact 13/16 inch length minimizes installation space requirements

Compatibility

Designed as an OEM-style threaded pipe bushing for use in 1-1/4 inch NPT piping systems requiring a 3/8 inch FNPT outlet, conforming to standard NPT thread specifications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable mechanical and plumbing codes. Depressurize and drain the piping system fully before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten; use a pipe wrench with a backup wrench on adjacent fittings to avoid stressing connected pipe.
