Merit Brass 6502-400 Ss Pipe Nipple 1/8 in Sch 80 316 316L

Product Description

The MERIT BRASS 6502-400 is a Schedule 80 seamless stainless steel pipe nipple sized for 1/8 inch pipe. Manufactured from Grade 316 and 316L stainless steel, it delivers strong corrosion resistance in aggressive environments including exposure to chlorides, acids, and caustic solutions. The seamless construction eliminates weld seams, reducing potential leak points and improving pressure integrity. This nipple is suited for plumbing, mechanical, and industrial piping systems where material compatibility and pressure rating matter. Licensed plumbers and pipefitters install this type of fitting as part of threaded pipe assemblies in both commercial and industrial applications.

This fitting is appropriate for use in residential and commercial piping systems that require corrosion-resistant threaded connections. The 1/8 inch pipe size makes it well suited for small-diameter instrument lines, chemical feed lines, compressed air systems, and similar low-volume service runs. The 316 and 316L dual-grade rating supports use in corrosive or high-purity environments where standard 304 stainless is not sufficient. Plumbers and mechanical contractors working in food processing, marine, chemical handling, or HVAC hydronic systems commonly specify this material grade.

Key Features

• Grade 316 and 316L stainless steel for superior corrosion resistance versus standard 304 stainless
• Seamless construction eliminates weld seams for improved pressure integrity
• Schedule 80 wall thickness provides a heavier wall than Schedule 40 for higher-pressure applications
• 1/8 inch pipe size for small-diameter threaded piping runs
• Threaded ends for direct assembly into standard NPT fittings and valves

Compatibility

Designed as an OEM-style replacement or new-installation fitting for threaded 1/8 inch NPT piping systems requiring Schedule 80 stainless steel construction.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC or ASME B31 piping codes. Shut off system pressure and depressurize the line completely before removing or installing any threaded fitting. Use appropriate thread sealant or PTFE tape rated for the service fluid and pressure range. Do not over-torque threaded connections, as stainless steel fittings are susceptible to galling.
