Merit Brass 6502-300 Ss Pipe Nipple 1/8 in Sch 80 316 316L

Product Description

The MERIT BRASS 6502-300 is a Schedule 80 seamless stainless steel pipe nipple sized for 1/8 inch pipe, manufactured from Grade 316/316L stainless steel. This close or short nipple provides a corrosion-resistant threaded connection in piping systems where standard carbon steel or brass fittings are not suitable. The seamless construction eliminates a weld seam, which reduces potential weak points under pressure or in chemically aggressive environments. Licensed plumbers, pipefitters, and industrial maintenance technicians install this type of nipple in process, utility, and mechanical systems requiring elevated corrosion resistance.

This nipple is suited for residential and commercial plumbing, HVAC, chemical process, and industrial piping applications where Grade 316 or 316L stainless steel is specified. The 316L designation indicates low carbon content, making it preferable in welded assemblies or in environments prone to intergranular corrosion. Schedule 80 wall thickness provides greater pressure capacity compared to Schedule 40, making it appropriate for higher-pressure service runs and tight-clearance instrument connections. It is commonly used in marine, food-service, and corrosive-fluid environments where standard steel fittings would degrade.

Key Features

• Grade 316/316L stainless steel construction for superior corrosion resistance
• Seamless pipe construction eliminates weld-seam vulnerabilities
• Schedule 80 wall thickness supports higher-pressure applications versus Schedule 40
• 1/8 inch pipe size fits standard NPT threaded fittings and valves of the same size
• Low-carbon 316L grade suitable for welded assemblies and aggressive media

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC and ASME B31 piping code requirements. Shut off and depressurize the affected piping system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant rated for stainless steel and the intended media before making up the joint. Avoid over-tightening threaded stainless fittings, as galling can occur when stainless steel threads are engaged without proper anti-seize or sealant compound.
