Merit Brass 4520-6000 Ss Pipe Nipple 1-1/4 in Sch 80 Gr 304

Product Description

The MERIT BRASS 4520-6000 is a seamless stainless steel pipe nipple designed for demanding piping applications where corrosion resistance and pressure integrity are critical. Manufactured from Grade 304 stainless steel with a Schedule 80 wall thickness, this nipple delivers greater wall strength compared to Schedule 40, making it suitable for higher-pressure and higher-temperature service. The seamless construction eliminates weld seams, reducing potential failure points in the pipe wall. It is sized for 1-1/4 inch pipe and is installed by licensed plumbers, pipefitters, and mechanical contractors working on industrial, commercial, and specialty residential systems.

This pipe nipple is used in plumbing, process piping, and mechanical systems where stainless steel is specified for corrosion resistance or sanitary requirements. Typical applications include chemical handling lines, steam service, food-grade piping, HVAC hydronic systems, and marine or coastal installations where carbon steel would be susceptible to corrosion. The Schedule 80 wall thickness makes it appropriate for systems operating at elevated pressures where a heavier wall is required by design or code.

Key Features

• Seamless construction eliminates weld seams for consistent wall integrity
• Grade 304 stainless steel provides strong corrosion and oxidation resistance
• Schedule 80 wall thickness supports higher operating pressures than Schedule 40
• 1-1/4 inch pipe size fits standard NPT fittings and valves of the same size
• Suitable for corrosive, sanitary, and high-temperature piping environments

Compatibility

Designed as an OEM-style replacement and standard-fit component for 1-1/4 inch NPT threaded piping systems requiring Grade 304 stainless steel Schedule 80 pipe nipples.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or ASME B31 piping codes. Shut off and depressurize the piping system completely before threading or replacing any nipple. Use appropriate thread sealant or PTFE tape rated for stainless steel and the intended service fluid. Avoid over-torquing threaded connections, which can crack fittings or gall stainless steel threads.
