Merit Brass 6502-150 Ss Pipe Nipple 1/8 in Sch 80 316 316L

Product Description

The MERIT BRASS 6502-150 is a Schedule 80 seamless stainless steel pipe nipple sized for 1/8 inch pipe thread connections. Manufactured from Grade 316/316L dual-certified stainless steel, this nipple delivers higher corrosion resistance than standard 304-grade fittings, making it well suited for aggressive media, salt exposure, and process piping where chloride resistance matters. The seamless construction eliminates weld seams, reducing potential failure points under pressure cycling. At 0.038 pounds, it is a compact fitting intended for tight plumbing assemblies where space and weight are a factor. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting as a close or short extension nipple in threaded piping systems.

This nipple is appropriate for residential and light commercial plumbing, HVAC, chemical, food service, and marine piping applications where stainless steel is specified. The 1/8 inch pipe size is commonly used on instrument taps, gauge connections, pilot lines, and small-diameter service lines. Schedule 80 wall thickness provides greater pressure-bearing capacity compared to Schedule 40, which is why this fitting appears in higher-pressure installations and systems subject to mechanical stress or vibration.

Key Features

• Grade 316/316L dual-certified stainless steel for superior corrosion resistance including chloride environments
• Seamless construction eliminates weld seams for consistent wall integrity under pressure
• Schedule 80 wall thickness rated for higher-pressure service than Schedule 40
• 1/8 inch NPT thread size fits standard tapered pipe thread connections
• Lightweight at 0.038 pounds, suitable for compact or instrument-scale assemblies

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC requirements for the system type. Shut off and depressurize the line completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the media being handled. Do not over-torque stainless fittings, as galling on stainless threads can occur without proper anti-seize compound or lubrication.
