Merit Brass 6524-550 Ss Pipe Nipple 1-1/2 in Sch 80 316L

Product Description

The MERIT BRASS 6524-550 is a seamless stainless steel pipe nipple designed for threaded piping systems requiring corrosion resistance and high-pressure capability. Manufactured from Grade 316/316L stainless steel, this nipple meets Schedule 80 wall thickness standards, making it suitable for demanding fluid handling and industrial process applications. The 316L designation indicates a low-carbon variant, which reduces the risk of carbide precipitation during welding and improves corrosion resistance in chloride-rich and chemical environments. Licensed plumbers and pipefitters install this component as part of threaded assemblies in systems handling corrosive media, high temperatures, or sanitary process fluids.

This pipe nipple is used in residential and commercial plumbing, HVAC hydronic systems, chemical processing lines, marine installations, and food-grade or sanitary piping applications where standard carbon steel or brass fittings are not appropriate. The 1-1/2 inch pipe size and NPT-compatible threading allow direct integration into standard Schedule 80 threaded piping assemblies. Its seamless construction eliminates weld seams, reducing potential failure points under pressure cycling or thermal expansion.

Key Features

• Grade 316/316L seamless stainless steel construction for superior corrosion resistance
• Schedule 80 wall thickness for high-pressure service
• 1-1/2 inch pipe size with standard NPT-compatible threaded ends
• Low-carbon 316L grade minimizes carbide precipitation risk in welded assemblies
• Seamless construction eliminates weld seam failure points

Compatibility

Designed as an OEM-style replacement or new-installation component for 1-1/2 inch Schedule 80 threaded stainless steel piping systems.

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 system completely before removing or installing any threaded pipe component. Use an appropriate thread sealant rated for stainless steel and compatible with the system media. Avoid over-torquing threaded connections, as excessive force can damage stainless steel threads.
