Merit Brass 3614D-2008 Pipe Bushing 1-1/4 X 1/2 in 316 Ss

Product Description

The MERIT BRASS 3614D-2008 is a hex pipe bushing designed to reduce a 1-1/4 inch male NPT fitting down to a 1/2 inch female NPT port. Constructed from 316/316L stainless steel, this bushing delivers strong corrosion resistance across a wide range of process fluids and environments. It carries a pressure rating of 3,000 psi, making it suitable for demanding fluid and gas piping applications. At 13/16 inches in length and 0.5 pounds, it is a compact, durable fitting intended for installation by licensed plumbers and pipefitters working in industrial, commercial, and marine piping systems.

This bushing is used wherever a line or branch connection must be reduced from a 1-1/4 inch pipe thread to a 1/2 inch pipe thread. Common install scenarios include instrument tapping, chemical process lines, offshore and marine systems, food-grade piping, and sanitary applications where standard carbon steel fittings would be unsuitable due to corrosion exposure. The 316/316L dual-grade material certification makes it compatible with both standard and weld-end fitting assemblies in corrosion-critical environments.

Key Features

• 316/316L stainless steel construction for superior corrosion resistance in aggressive media
• 3,000 psi pressure rating suitable for high-pressure piping service
• MNPT x FNPT end connections for standard threaded pipe assembly
• Reduces 1-1/4 inch male thread to 1/2 inch female thread in a single fitting
• Compact 13/16 inch body length minimizes installation footprint
• Dual-grade 316/316L certification supports broad code and specification compliance

Compatibility

Designed as an OEM-style replacement or new-installation threaded pipe bushing for 1-1/4 inch to 1/2 inch NPT reduction applications in stainless steel piping systems.

Installation Notes

Installation is performed by a licensed plumber or pipefitter in accordance with applicable plumbing and piping codes such as the IPC or ASME B31.3. Isolate and depressurize the line completely before removing or installing any threaded fittings. Apply an appropriate thread sealant rated for stainless steel and the service medium. Do not over-torque NPT threads, as stainless steel fittings are susceptible to galling.
