Merit Brass 6508-800 Stainless Steel Pipe Nipple 1/2 in Sch 80

Product Description

The MERIT BRASS 6508-800 is a seamless stainless steel pipe nipple designed for high-pressure and corrosion-resistant piping applications. Manufactured from Grade 316/316L stainless steel and built to Schedule 80 wall thickness, this nipple delivers the added strength and corrosion resistance required in demanding fluid and gas distribution systems. The 1/2 inch pipe size and 1/2 inch threaded connections make it a direct-fit component for standard NPT piping assemblies. Plumbers, pipefitters, and mechanical contractors working in chemical, marine, food service, or industrial environments routinely specify 316/316L fittings for their superior resistance to chloride and pitting corrosion.

This pipe nipple is suited for residential and commercial plumbing, HVAC hydronic systems, industrial process piping, and marine applications where moisture, chemicals, or high-purity requirements rule out carbon steel or standard 304 stainless fittings. Schedule 80 construction provides thicker walls than Schedule 40, making this nipple appropriate for elevated-pressure service lines. It is commonly installed in compressed air, steam, water, and chemical distribution runs that demand reliable threaded connections under stress.

Key Features

• Grade 316/316L stainless steel construction for superior chloride and pitting corrosion resistance
• Seamless manufacturing process eliminates weld seams for consistent wall integrity
• Schedule 80 wall thickness rated for higher-pressure service compared to Schedule 40
• 1/2 inch NPT threaded connections for compatibility with standard pipe fittings and valves
• Dual-certified 316/316L material meets both standard and low-carbon grade requirements

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 1/2 inch NPT threaded piping systems requiring Schedule 80, Grade 316 or 316L seamless stainless steel construction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC or ASME B31.1/B31.3 piping codes. Shut off and depressurize the system fully before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape rated for the service medium to all male threads before assembly. Do not over-torque threaded connections, as stainless steel threads are susceptible to galling.
