Merit Brass 6520-7200 Ss Pipe Nipple 1-1/4 in Sch 80 316

Product Description

The MERIT BRASS 6520-7200 is a Schedule 80 seamless stainless steel pipe nipple sized for 1-1/4 inch pipe, manufactured from Grade 316 stainless steel. This nipple is used to connect sections of pipe in plumbing, industrial, and process piping systems where corrosion resistance and pressure integrity are required. The seamless construction eliminates weld seams, reducing potential failure points under pressure or cyclic stress. Grade 316 stainless steel provides superior resistance to chlorides and acidic environments compared to Grade 304. Schedule 80 wall thickness meets the demands of higher-pressure service conditions. Licensed plumbers and pipefitters are the primary installers.

This nipple is suited for residential and commercial plumbing, HVAC hydronic systems, industrial process lines, and marine or coastal installations where chloride exposure is a concern. The 1-1/4 inch pipe size fits standard threaded fittings in that size class. Its seamless Schedule 80 construction makes it appropriate for steam, chemical, and high-pressure fluid service applications where wall integrity is critical.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in chloride and acidic environments
• Seamless construction eliminates weld seams for consistent wall integrity under pressure
• Schedule 80 wall thickness rated for higher-pressure service compared to Schedule 40
• 1-1/4 inch pipe size with standard NPT-compatible threading for broad fitment
• UNSPSC Code 40173300 for procurement and catalog classification

Compatibility

Designed as an OEM-style replacement or new-installation nipple for 1-1/4 inch threaded pipe systems using Schedule 80 fittings and valves in plumbing, HVAC, and industrial process piping.

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 appropriate thread sealant or PTFE tape rated for stainless steel and the intended service medium. Avoid over-torquing threaded connections, as this can stress the nipple body or damage mating fittings.
