Merit Brass 6524-500 Ss Pipe Nipple 1-1/2 in Sch 80 316 316L

Product Description

The MERIT BRASS 6524-500 is a seamless stainless steel pipe nipple designed for high-pressure and corrosion-resistant piping applications. Built to Schedule 80 wall thickness and manufactured from Grade 316/316L stainless steel, this nipple delivers the strength and chemical resistance required in demanding plumbing, industrial, and mechanical systems. The 1-1/2 inch pipe size with matching 1-1/2 inch thread size makes it a direct-fit component for standard NPT threaded assemblies. Licensed plumbers and pipefitters install this type of fitting where Schedule 40 wall thickness is insufficient or where corrosive media, saltwater exposure, or sanitary requirements call for 316L stainless alloy.

This pipe nipple is suited for residential and commercial piping systems where corrosion resistance is critical. Typical applications include chemical processing lines, marine plumbing, food-service and sanitary piping, coastal HVAC condensate lines, and potable water systems requiring stainless fittings. The Grade 316/316L dual certification means the nipple meets both standard and low-carbon requirements, making it compatible with welded or threaded assemblies where carbide precipitation is a concern.

Key Features

• Grade 316/316L dual-certified stainless steel for superior corrosion resistance
• Seamless construction eliminates weld seams for consistent wall integrity under pressure
• Schedule 80 wall thickness supports higher working pressures than Schedule 40
• 1-1/2 inch NPT thread size for direct integration into standard threaded piping systems
• Low-carbon 316L designation suitable for assemblies sensitive to carbide precipitation

Compatibility

Designed as an OEM-style replacement and standard-fit component for 1-1/2 inch NPT threaded Schedule 80 stainless steel piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC and local plumbing code requirements. Shut off and depressurize the system fully before removing or installing any threaded nipple. Use appropriate thread sealant or PTFE tape rated for stainless steel and the intended media. Avoid over-torquing threaded stainless connections, as galling can occur on stainless-to-stainless assemblies without proper anti-seize compound.
