Merit Brass 4516-7200 Ss Pipe Nipple 1 in Sch 80 Gr 304

Product Description

The MERIT BRASS 4516-7200 is a seamless stainless steel pipe nipple intended for use in demanding fluid and gas piping systems where corrosion resistance and pressure integrity are required. Built to Schedule 80 wall thickness from Grade 304 stainless steel, this nipple delivers greater wall strength than standard Schedule 40 fittings. It suits plumbing, process piping, and mechanical systems where the pipe size is 1 inch. Licensed plumbers and pipefitters typically specify this fitting when working with corrosive media, high-humidity environments, or sanitary system requirements that rule out carbon steel or galvanized alternatives.

This nipple is designed for 1-inch pipe applications across residential, commercial, and light industrial installations. Typical use cases include connecting valves, pumps, and equipment in water supply, chemical transfer, food service, and HVAC hydronic systems. The seamless construction and Schedule 80 wall thickness make it appropriate for higher-pressure service conditions where a welded seam would introduce a potential failure point. It is sold individually and is compatible with standard 1-inch NPT threaded fittings and valves.

Key Features

• Schedule 80 wall thickness for higher pressure ratings versus Schedule 40
• Seamless construction eliminates weld-seam vulnerabilities
• Grade 304 stainless steel provides corrosion resistance in wet and mildly corrosive environments
• 1-inch pipe size fits standard NPT threaded connections
• Suitable for plumbing, process, and hydronic piping applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch NPT threaded piping systems requiring Schedule 80 seamless stainless steel construction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC codes and local jurisdiction requirements. De-pressurize and drain the system before removing or installing any threaded nipple. Apply an appropriate thread sealant or PTFE tape rated for stainless steel and the intended media before making up the joint. Avoid over-tightening, which can stress the threads or crack mating cast fittings.
