Merit Brass 6520-600 Ss Pipe Nipple 1-1/4 in Grade 316 Sch 80

Product Description

The MERIT BRASS 6520-600 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 provides superior resistance to chlorides, acids, and marine environments compared to standard 304-grade fittings. The 1-1/4 inch pipe size and threaded ends make it a direct-connect fitting for joining pipe sections or transitioning between components. Plumbers, pipefitters, and mechanical contractors typically install this type of fitting in process piping, chemical handling lines, and industrial fluid systems.

This nipple is suited for both residential and commercial installations where stainless steel is specified for durability or code compliance. Common applications include potable water supply lines, steam systems, chemical process piping, and marine plumbing where Grade 316 stainless is preferred for its molybdenum content and elevated corrosion resistance. The seamless construction eliminates weld seams, reducing potential failure points in high-cycle or high-pressure service environments.

Key Features

• Grade 316/316L stainless steel construction for enhanced corrosion resistance in chloride-heavy environments
• Seamless pipe body eliminates weld seams for consistent wall integrity under pressure
• Schedule 80 wall thickness provides additional strength over Schedule 40 for demanding service conditions
• 1-1/4 inch threaded pipe size for standard NPT connections
• Suitable for chemical, marine, industrial, and potable water piping systems

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local mechanical codes. Shut off and depressurize the line completely before removing or installing any threaded fittings. Use a pipe thread sealant rated for stainless steel and compatible with the system fluid. Avoid over-torquing threaded joints, as stainless steel threads are susceptible to galling.
