Merit Brass 6520-6000 Ss Pipe Nipple 1-1/4 in Sch 80 316

Product Description

The MERIT BRASS 6520-6000 is a Schedule 80 seamless stainless steel pipe nipple sized for 1-1/4 inch pipe. Manufactured from Grade 316 stainless steel, this nipple offers strong resistance to corrosion and pitting, making it well suited for demanding fluid and gas transfer applications. The seamless construction eliminates weld seams, reducing potential failure points under pressure cycling and thermal stress. Plumbers, pipefitters, and mechanical contractors install this type of fitting where standard carbon steel or Grade 304 stainless would be insufficient due to chemical exposure or high-moisture environments.

This pipe nipple is used in residential and commercial plumbing, HVAC hydronic systems, process piping, and marine or coastal installations where chloride exposure is a concern. Grade 316 stainless is the standard choice for applications involving salt water, mild acids, or caustic solutions. Schedule 80 wall thickness supports higher pressure ratings compared to Schedule 40 of the same nominal size, making this fitting appropriate for elevated-pressure service runs.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance
• Seamless pipe body eliminates weld seams and associated stress points
• Schedule 80 wall thickness supports higher working pressures than Schedule 40
• 1-1/4 inch nominal pipe size fits standard NPT threaded connections
• Suitable for corrosive fluid, high-moisture, and marine service environments

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and ASME B31 piping codes. Shut off system pressure and drain the line before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for stainless steel and the media being conveyed. Avoid over-torquing threaded connections on stainless fittings, as galling can occur without proper anti-seize compound or rated thread lubricant.
