Merit Brass 6502-550 Ss Pipe Nipple 1/8 in Sch 80 316 316L

Product Description

The MERIT BRASS 6502-550 is a Schedule 80 seamless stainless steel pipe nipple sized for 1/8-inch pipe. Manufactured from Grade 316/316L stainless steel, this nipple offers strong corrosion resistance in demanding environments where standard steel or brass fittings fall short. The seamless construction eliminates weld seams, reducing potential failure points under pressure or thermal cycling. It is a standard threaded fitting used by plumbers, pipefitters, and HVAC technicians when connecting pipe runs in corrosive or high-purity service conditions. The 316/316L dual-grade designation makes it suitable for applications requiring both weld and non-weld compliance.

This pipe nipple is well suited for residential and commercial plumbing, chemical process lines, food-grade systems, and marine or coastal installations where chloride exposure is a concern. The 1/8-inch pipe size fits small-diameter threaded connections typical of instrumentation, gauge ports, and low-flow service lines. It is also used in HVAC hydronic systems and steam applications where corrosion resistance is a priority. The Schedule 80 wall thickness provides additional pressure capacity compared to Schedule 40, making it appropriate for higher-pressure service runs.

Key Features

• Grade 316/316L stainless steel construction for superior corrosion resistance including chloride environments
• Seamless construction eliminates weld seams for improved pressure integrity
• Schedule 80 wall thickness for higher-pressure service capacity
• 1/8-inch pipe size fits standard NPT threaded connections
• Dual-grade 316/316L designation meets both standard and weld-compliance requirements

Compatibility

Designed as a standard NPT-threaded replacement or new-installation nipple for 1/8-inch pipe systems requiring Schedule 80 stainless steel fittings in corrosive or high-purity service applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and ASME B31 piping codes. Shut off and depressurize the system before removing or installing any threaded fitting. Use an appropriate thread sealant rated for stainless steel and the intended service medium. Avoid over-torquing NPT threads, as stainless steel is susceptible to galling without proper anti-seize compound or sealant tape.
