Merit Brass K414-1612 Pipe Bushing 1x3/4 in 304 Ss

Product Description

The MERIT BRASS K414-1612 is a threaded pipe bushing designed to reduce a 1-inch female connection down to a 3/4-inch male connection in pressurized piping systems. Constructed from 304 stainless steel, this Schedule 40 bushing connects via MNPT x FNPT threads and carries a 150 psi pressure rating. It meets ISO standards, making it a reliable choice for plumbing and process piping where corrosion resistance and thread integrity are required. Plumbers and pipefitters install this type of bushing when transitioning between pipe sizes within a threaded system.

This bushing is suited for residential and light commercial plumbing, as well as industrial and process piping applications where stainless steel is specified for corrosion resistance or sanitary requirements. It is appropriate for use in water supply lines, compressed air systems, and other fluid-handling systems rated within its 150 psi working pressure. The 304 stainless steel construction makes it a practical choice in environments exposed to moisture, mild chemicals, or temperature variation.

Key Features

• 304 stainless steel construction for corrosion resistance in wet and chemical-exposed environments
• MNPT x FNPT threaded connection for tool-compatible, leak-resistant assembly
• 150 psi pressure rating suitable for a wide range of fluid and gas piping applications
• Schedule 40 wall thickness for added strength and durability
• ISO-compliant design ensures dimensional consistency with standard threaded fittings
• 1 inch to 3/4 inch reducing configuration for common pipe-size transitions

Compatibility

Designed as an OEM-style replacement or new-installation bushing for Schedule 40 threaded piping systems using NPT connections at 150 psi or below.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters in accordance with applicable local plumbing codes and IPC guidelines. Shut off and depressurize the system before disassembly or fitting installation. Apply thread sealant or PTFE tape to the male threads before assembly and hand-tighten before using a pipe wrench to avoid cross-threading. Do not exceed the rated working pressure of 150 psi.
