Merit Brass 6516-4800 Ss Pipe Nipple 1 in Sch 80 Grade 316

Product Description

The MERIT BRASS 6516-4800 is a seamless stainless steel pipe nipple designed for high-pressure and corrosion-resistant piping applications. Manufactured from Grade 316 stainless steel and rated to Schedule 80 wall thickness, this nipple delivers reliable performance in demanding fluid and gas systems. The seamless construction eliminates weld seams, reducing potential failure points under pressure or cyclic stress. Plumbers, pipefitters, and industrial maintenance technicians typically specify this fitting where elevated corrosion resistance and heavier wall strength are required.

This pipe nipple is suited for use in commercial and industrial piping systems handling corrosive media, chemicals, saltwater, or high-purity fluids where standard carbon steel or Grade 304 stainless would be insufficient. The 1 inch pipe size and Schedule 80 rating make it appropriate for process piping, marine installations, food-service lines, and chemical transfer systems. It threads directly into standard NPT female fittings, valves, or equipment ports of the same pipe size.

Key Features

• Grade 316 stainless steel construction for superior chloride and corrosion resistance compared to Grade 304
• Seamless construction eliminates weld seams for consistent wall integrity under pressure
• Schedule 80 wall thickness provides greater pressure capacity than Schedule 40
• 1 inch nominal pipe size for compatibility with standard NPT threaded fittings and equipment
• Suitable for corrosive, chemical, and marine piping environments

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1 inch NPT threaded piping systems requiring Schedule 80 Grade 316 seamless stainless steel nipples.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters in accordance with applicable IPC or ASME B31 piping code requirements. Depressurize and drain the system fully before removing or installing any threaded pipe fitting. Apply an appropriate thread sealant rated for stainless steel and the intended media. Avoid over-torquing threaded connections, which can gall stainless steel threads and cause fitting damage.
