Merit Brass 6506-250 Stainless Steel Pipe Nipple 3/8 in Sch 80

Product Description

The MERIT BRASS 6506-250 is a seamless stainless steel pipe nipple designed for threaded piping systems in demanding service environments. Manufactured from Grade 316/316L stainless steel and rated to Schedule 80 wall thickness, this nipple delivers higher pressure capacity and greater corrosion resistance than standard 304-grade fittings. The 3/8 inch pipe size with matching 3/8 inch thread size makes it a direct-fit component for plumbing, HVAC, and industrial process lines. Licensed plumbers, pipefitters, and mechanical contractors install this type of fitting where elevated wall thickness and stainless-steel alloy grade matter most.

This nipple is suited for residential and commercial installations where corrosion resistance is a priority — including potable water systems, chemical handling lines, marine environments, and steam or high-moisture mechanical rooms. Schedule 80 wall thickness supports higher working pressures compared to Schedule 40, making it appropriate for process piping applications. Its seamless construction eliminates weld seams, reducing potential failure points along the fitting body.

Key Features

• Seamless construction — no weld seam, uniform wall thickness throughout
• Grade 316/316L stainless steel — enhanced resistance to chlorides and acidic environments
• Schedule 80 wall thickness — increased pressure rating over Schedule 40
• 3/8 inch pipe size with 3/8 inch threaded ends for standard NPT connections
• Lightweight at 0.146 pounds — minimal added load to piping assemblies

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/8 inch Schedule 80 threaded stainless steel piping systems using NPT-standard connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and IFGC code requirements for the jurisdiction. Shut off system pressure and drain the line before removing or installing any threaded nipple. Apply appropriate thread sealant or PTFE tape rated for the service medium — verify chemical compatibility when used in non-water applications. Do not over-torque threaded connections on stainless fittings, as galling can occur without proper anti-seize compound.
