Merit Brass 6520-250 Ss Pipe Nipple 1-1/4 in Grade 316 Sch 80

Product Description

The MERIT BRASS 6520-250 is a seamless stainless steel pipe nipple designed for threaded pipe assemblies in demanding industrial and commercial plumbing applications. Manufactured from Grade 316 and 316L stainless steel, this nipple offers strong resistance to corrosion, including chloride environments and chemical exposure. It is built to Schedule 80 wall thickness, providing extra strength for higher-pressure systems. At 1-1/4 inch pipe size with matching 1-1/4 inch thread, it fits standard NPT pipe systems. The seamless construction eliminates weld seams, reducing potential failure points in critical installations. Licensed plumbers and pipefitters are the primary installers of this component.

This pipe nipple is suited for residential and commercial plumbing, HVAC piping systems, industrial process lines, and chemical handling systems where stainless steel is specified. Its Grade 316 and 316L dual certification makes it appropriate for marine environments, food processing facilities, and corrosive-fluid service where carbon steel or lower-grade stainless would be inadequate. Schedule 80 wall thickness makes it a common choice when piping must meet pressure ratings above standard Schedule 40 requirements.

Key Features

• Grade 316 and 316L stainless steel construction for superior corrosion resistance
• Seamless manufacturing eliminates weld seams for improved pressure integrity
• Schedule 80 wall thickness for higher-pressure service compared to Schedule 40
• 1-1/4 inch NPT thread size for compatibility with standard threaded pipe fittings
• Dual-grade 316 and 316L certification supports a broad range of code and specification requirements

Compatibility

Designed as an OEM-style replacement or new-installation component for 1-1/4 inch NPT threaded pipe systems requiring Schedule 80 stainless steel pipe nipples.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the piping system completely before removing or installing any threaded nipple. Use a thread sealant or PTFE tape rated for stainless steel and compatible with the service fluid. Avoid over-tightening, which can crack or gall stainless steel threads; use a pipe wrench with a backup wrench on adjacent fittings to prevent stress on the connected piping.
