Merit Brass 6504-550 Ss Pipe Nipple 1/4 in Sch 80 316 316L

Product Description

The MERIT BRASS 6504-550 is a seamless stainless steel pipe nipple designed for threaded pipe assemblies in demanding fluid and gas distribution systems. Manufactured from Grade 316/316L stainless steel, this nipple offers strong resistance to corrosion, chlorides, and high-temperature environments. Built to Schedule 80 wall thickness, it provides greater pressure capacity than standard Schedule 40 fittings. The 1/4 inch pipe size and matching 1/4 inch thread size make it a direct fit for compact piping runs. Licensed plumbers and pipefitters install this type of fitting in commercial, industrial, and marine applications where corrosion resistance is critical.

This pipe nipple is suited for use in plumbing, HVAC hydronic systems, chemical processing lines, marine installations, and other environments where 316 or 316L stainless steel is specified for its molybdenum-enhanced corrosion resistance. The seamless construction eliminates weld seams, which is important in high-pressure or high-purity service. The Schedule 80 wall thickness makes this nipple appropriate for systems operating at elevated pressures compared to standard-weight fittings.

Key Features

• Grade 316/316L stainless steel construction for superior corrosion resistance including chloride environments
• Seamless pipe construction eliminates weld-zone vulnerabilities
• Schedule 80 wall thickness for higher pressure ratings versus Schedule 40
• 1/4 inch pipe size with matching 1/4 inch NPT thread
• Suitable for plumbing, hydronic, marine, and industrial piping systems

Compatibility

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

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and ASME B31 piping codes. Depressurize and drain the system fully before removing or installing any threaded fitting. Use an appropriate thread sealant or PTFE tape rated for stainless steel and the service fluid. Do not overtighten threaded stainless fittings, as galling can occur on stainless threads without proper lubrication.
