Merit Brass 6520-1000 Stainless Steel Pipe Nipple Sch 80

Product Description

The MERIT BRASS 6520-1000 is a seamless stainless steel pipe nipple designed for demanding piping applications where corrosion resistance and pressure integrity are critical. Manufactured from Grade 316/316L stainless steel and rated to Schedule 80 wall thickness, this nipple delivers reliable performance in aggressive chemical, industrial, and marine environments. The 1-1/4 inch pipe size suits a wide range of commercial and industrial piping systems. Licensed plumbers and pipefitters install this fitting as part of threaded piping assemblies where standard carbon steel would corrode or fail under service conditions.

This pipe nipple is suited for commercial and industrial piping systems handling corrosive fluids, chemicals, saltwater, or high-moisture environments. Schedule 80 wall construction supports higher pressure ratings compared to standard Schedule 40 fittings. The Grade 316/316L dual certification makes it appropriate for both standard and low-carbon applications where weld decay concerns are relevant. Typical installations include process piping, marine plumbing, food service lines, and chemical transfer systems.

Key Features

• Grade 316/316L stainless steel construction for superior corrosion resistance in harsh environments
• Seamless manufacturing eliminates weld seams, supporting consistent wall integrity and pressure performance
• Schedule 80 wall thickness rated for higher-pressure service than Schedule 40
• 1-1/4 inch pipe size with matching 1-1/4 inch thread size for direct compatibility with standard NPT fittings
• Dual 316/316L material certification suitable for applications requiring low-carbon stainless

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with 1-1/4 inch NPT threaded piping systems requiring Schedule 80 stainless steel components.

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 piping system completely before removing or installing any threaded fitting. Use an appropriate thread sealant or PTFE tape rated for stainless steel and the specific fluid being conveyed. Avoid over-torquing threaded connections on stainless steel, as galling can permanently damage threads.
