Merit Brass K414-1208 Pipe Bushing 3/4 X 1/2 Inch 304 Ss

Product Description

The MERIT BRASS K414-1208 is a threaded pipe bushing designed to reduce a 3/4 inch male NPT connection down to a 1/2 inch female NPT connection. Constructed from 304 stainless steel, it offers solid corrosion resistance in wet, chemical-exposed, or outdoor plumbing environments. Rated at 150 psi, this Schedule 40 fitting meets ISO standards and is suited for use in water, light oil, and compatible fluid systems. Licensed plumbers and pipefitters install this type of bushing when reducing pipe sizes within a threaded piping assembly.

This bushing fits standard threaded piping installations in residential and light commercial plumbing, HVAC hydronic systems, and industrial fluid distribution lines where a 3/4 inch to 1/2 inch reduction is required. The MNPT x FNPT configuration allows it to thread directly into a female pipe fitting or valve port on one end while accepting a 1/2 inch male-threaded pipe on the other. It is commonly used in pump headers, manifold assemblies, and service valve installations.

Key Features

• 304 stainless steel construction provides corrosion resistance in wet and chemically active environments
• 3/4 inch MNPT x 1/2 inch FNPT threaded ends for direct pipe-to-pipe size reduction
• 150 psi pressure rating suitable for low- to medium-pressure service lines
• Schedule 40 wall thickness meets standard piping system requirements
• ISO standards compliance for consistent thread form and fit

Compatibility

Designed as an OEM-style replacement or new-install threaded pipe bushing for Schedule 40 plumbing and piping systems using standard NPT threaded fittings in 3/4 inch to 1/2 inch reducing configurations.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten stainless steel threaded fittings, as galling of the threads can occur.
