Merit Brass 6520-1200 Ss Pipe Nipple 1-1/4 in Grade 316 Sch 80

Product Description

The MERIT BRASS 6520-1200 is a seamless stainless steel pipe nipple sized for 1-1/4 inch pipe, constructed from Grade 316/316L stainless steel to Schedule 80 wall thickness. This nipple is used to make threaded pipe connections in systems where corrosion resistance and pressure integrity are critical. The Schedule 80 wall provides greater wall thickness and higher pressure ratings compared to Schedule 40. Grade 316/316L offers superior resistance to chlorides and chemical exposure, making it appropriate for demanding fluid handling, process piping, and mechanical systems. Licensed plumbers and pipefitters are the primary installers in both commercial and industrial settings.

This pipe nipple is suited for use in plumbing, process piping, chemical handling, and marine applications where stainless steel is specified for corrosion resistance. The 1-1/4 inch thread size fits standard NPT threaded fittings and valves of the same nominal size. Its seamless construction eliminates weld seams, which is important in high-pressure and high-purity service. It is a common replacement or extension component in existing threaded stainless steel piping systems found in commercial facilities, industrial plants, and marine environments.

Key Features

• Grade 316/316L stainless steel for strong resistance to chlorides and corrosive media
• Schedule 80 wall thickness for increased pressure capacity over standard Schedule 40
• Seamless construction with no weld seams for consistent wall integrity
• 1-1/4 inch NPT threaded ends for compatibility with standard threaded fittings
• Suitable for plumbing, chemical, process, and marine piping applications

Compatibility

Designed as an OEM-style replacement or addition for threaded stainless steel pipe systems using 1-1/4 inch nominal pipe size with NPT fittings.

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. Apply an appropriate thread sealant rated for stainless steel and the service media. Avoid overtightening, which can stress the threads; use a pipe wrench sized for the fitting and follow accepted hand-tight-plus-turns practice for threaded NPT connections.
