Merit Brass 4506-7200 Pipe Nipple 3/8 in Sch 80 SS304

Product Description

The MERIT BRASS 4506-7200 is a seamless stainless steel pipe nipple designed for use in high-pressure and corrosion-resistant piping systems. Built to Schedule 80 wall thickness and manufactured from Grade 304 stainless steel, this nipple delivers the structural integrity and chemical resistance required in demanding mechanical, plumbing, and industrial applications. The 3/8 inch pipe size makes it suitable for small-diameter branch connections and instrument piping runs. Licensed plumbers, pipefitters, and mechanical contractors specify Schedule 80 seamless construction when system pressure ratings and longevity in corrosive environments are priorities.

This nipple is well suited for residential and commercial plumbing systems, HVAC hydronic piping, compressed air lines, and light industrial process piping where Grade 304 stainless steel is specified for corrosion resistance. The 3/8 inch size fits standard close or short nipple applications in tight spaces and instrument connections. It is commonly used in water treatment, food service, and marine environments where carbon steel or brass fittings are not appropriate.

Key Features

• Seamless construction for uniform wall thickness and higher pressure tolerance versus welded nipples
• Schedule 80 wall thickness provides greater pressure rating compared to Schedule 40
• Grade 304 stainless steel resists corrosion in wet, chemical, and marine environments
• 3/8 inch pipe size for small-diameter branch, instrument, and utility connections
• Threaded ends for standard NPT fitting compatibility

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 3/8 inch NPT threaded fittings, valves, and pipe in Schedule 80 stainless steel piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and ASME B31 piping codes. Shut off system pressure and drain the line before removing or installing any threaded nipple. Apply an appropriate thread sealant or PTFE tape rated for stainless steel and the intended service fluid. Avoid over-tightening, which can stress seamless stainless fittings and compromise thread integrity.
