Merit Brass 3414D-0602 Pipe Bushing 3/8 X 1/8 in Ss

Product Description

The MERIT BRASS 3414D-0602 is a threaded pipe bushing used to reduce a 3/8 inch female pipe thread port down to a 1/8 inch male pipe thread connection. Constructed from 304/304L stainless steel, this fitting delivers reliable corrosion resistance in demanding service environments. It is rated to 3,000 psi, making it suitable for high-pressure fluid and gas piping systems. The MNPT x FNPT end configuration allows direct installation into a female-threaded fitting or port without additional adapters. Plumbers, pipefitters, and mechanical contractors install this type of bushing during new construction and retrofit work where reducing thread sizes is required.

This bushing is appropriate for use in residential and commercial piping systems where stainless steel construction is specified for corrosion resistance, cleanliness, or code compliance. Typical applications include process piping, instrumentation lines, hydraulic assemblies, and compressed-air or fluid distribution systems where a thread reduction from 3/8 inch to 1/8 inch NPT is needed. The 304/304L dual-certified material grade broadens its suitability across both standard and low-carbon stainless steel specifications.

Key Features

• 304/304L stainless steel construction for broad corrosion resistance
• 3,000 psi pressure rating for high-pressure service
• MNPT x FNPT threaded ends for tool-installable connections without welding
• Reduces 3/8 inch female port to 1/8 inch male pipe thread
• Dual-certified 304/304L material grade meets low-carbon stainless requirements

Compatibility

Designed as an OEM-style threaded pipe bushing for use in 3/8 inch female NPT ports requiring a 1/8 inch MNPT outlet in stainless steel piping systems.

Installation Notes

Install using appropriately sized pipe wrenches or hex-drive tools rated for stainless steel fittings. Apply a suitable thread sealant or PTFE tape to the male threads per system requirements and applicable plumbing or mechanical codes. Depressurize and isolate the system completely before removing any existing fitting or installing this bushing. Avoid over-torquing stainless steel threads to prevent galling.
