Merit Brass 6506-001 Ss Pipe Nipple 3/8 in Sch 80 316 316L

Product Description

The MERIT BRASS 6506-001 is a seamless stainless steel pipe nipple designed for threaded pipe assemblies in demanding fluid and gas handling systems. Manufactured from Grade 316 and 316L stainless steel, this nipple delivers strong corrosion resistance in aggressive environments including chemical exposure, marine applications, and high-moisture industrial settings. Built to Schedule 80 wall thickness, it handles elevated pressure loads that standard Schedule 40 fittings cannot. The 3/8 inch pipe size fits common small-bore piping configurations. Licensed plumbers and pipefitters install this type of nipple when system requirements call for high-integrity, corrosion-resistant threaded connections.

This nipple is suited for use in residential and commercial plumbing, industrial process piping, HVAC condensate and refrigerant piping accessories, and chemical handling lines where Grade 316 or 316L material is specified. The 316L variant offers lower carbon content, making it appropriate for welded assemblies where sensitization is a concern. Applications include corrosive fluid transfer, salt-water-adjacent systems, food-grade piping, and sanitary installations where standard carbon steel or brass fittings are not acceptable.

Key Features

• Grade 316 and 316L stainless steel construction for superior corrosion resistance
• Seamless construction eliminates weld seams, supporting higher pressure integrity
• Schedule 80 wall thickness for elevated pressure applications
• 3/8 inch pipe size with matching 3/8 inch thread size
• UNSPSC Code 40173300 for procurement system compatibility

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 80 threaded pipe systems requiring 3/8 inch stainless steel nipples in Grade 316 or 316L.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable plumbing codes such as the IPC. Shut off and depressurize the system completely before removing or installing any threaded fitting. Use appropriate thread sealant or PTFE tape rated for the service fluid and pressure. Do not overtighten threaded stainless fittings, as galling of stainless threads can cause permanent damage.
