Merit Brass 6506-3600 Ss Pipe Nipple 3/8 in Sch 80 316

Product Description

The MERIT BRASS 6506-3600 is a Schedule 80 seamless stainless steel pipe nipple sized for 3/8 inch pipe. Manufactured from Grade 316 stainless steel, it delivers strong corrosion resistance in demanding fluid and gas piping systems. The seamless construction eliminates weld seams, reducing potential leak points and improving pressure integrity. Schedule 80 wall thickness makes it well suited for higher-pressure applications where standard Schedule 40 fittings are insufficient. Plumbers, pipefitters, and mechanical contractors install this nipple as a threaded connector between pipe sections, valves, and fittings in process, HVAC, and plumbing systems.

This nipple is appropriate for residential and commercial piping installations where corrosion resistance is a primary requirement — including saltwater environments, chemical exposure, and food-grade or sanitary systems. Grade 316 stainless offers improved resistance to chlorides and pitting compared to Grade 304, making it the preferred choice in coastal, marine, and industrial process environments. The 3/8 inch size is commonly used in instrumentation lines, compressed air distribution, and small-bore fluid piping runs.

Key Features

• Grade 316 stainless steel construction for superior chloride and corrosion resistance
• Seamless construction eliminates weld seams for improved pressure integrity
• Schedule 80 wall thickness rated for higher-pressure service
• 3/8 inch pipe size fits standard NPT threaded connections
• Suitable for process, HVAC, plumbing, and industrial fluid systems

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 3/8 inch NPT threaded pipe systems requiring Schedule 80 stainless steel nipples.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and ASME B31 piping code requirements. Shut off and depressurize the line fully before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the service fluid before threading the nipple into place. Do not overtighten threaded connections on stainless fittings, as galling can occur — use calibrated torque where required by the system specification.
