Merit Brass 6532-500 Ss Pipe Nipple 2in Grade 316 Sch 80

Product Description

The MERIT BRASS 6532-500 is a Grade 316/316L stainless steel pipe nipple designed for demanding piping applications in plumbing, HVAC, and industrial systems. Constructed seamlessly to Schedule 80 wall thickness, this 2-inch nipple delivers higher pressure and corrosion resistance compared to standard Schedule 40 fittings. The 316/316L dual-grade designation means it meets both the standard and low-carbon specifications, making it suitable for welded assemblies and high-chloride environments. Licensed plumbers and pipefitters install this type of nipple as a threaded connector between fittings, valves, and equipment in both new construction and retrofit work.

This nipple is well suited for commercial and industrial piping systems where corrosion resistance is a primary concern, including chemical process lines, marine environments, food-service installations, and high-humidity mechanical rooms. The Schedule 80 wall thickness supports higher working pressures than Schedule 40, making it a common choice for steam, compressed air, and fluid transfer lines. It is also used in residential and light commercial plumbing where stainless steel is specified for longevity or code compliance.

Key Features

• Grade 316/316L dual-certified stainless steel for superior corrosion resistance in chloride-rich and chemical environments
• Seamless construction eliminates weld seams that can be weak points under pressure or in corrosive service
• Schedule 80 wall thickness provides increased pressure ratings versus standard Schedule 40 nipples
• 2-inch pipe size fits standard NPT threaded fittings, valves, and flanges
• Low-carbon 316L designation makes it compatible with welded piping assemblies without sensitization concerns

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with the International Plumbing Code and applicable local codes. Shut off and depressurize the system completely before removing or installing threaded pipe nipples. Use appropriate thread sealant or PTFE tape rated for the service fluid and temperature range. Avoid over-tightening threaded connections, which can stress the fitting and damage threads.
