Merit Brass 6504-450 Ss Pipe Nipple 1/4 in Sch 80 316 316L

Product Description

The MERIT BRASS 6504-450 is a seamless stainless steel pipe nipple designed for high-pressure and corrosion-resistant piping applications. Manufactured from Grade 316 and 316L stainless steel, it meets the demands of systems where chemical resistance and structural integrity are critical. Built to Schedule 80 wall thickness, this nipple handles elevated pressure loads that Schedule 40 fittings cannot. The 1/4 inch pipe size and matching 1/4 inch thread size make it a direct-fit component for small-bore piping runs. Plumbers, pipefitters, and mechanical contractors install this type of fitting in process, industrial, and commercial plumbing systems.

This pipe nipple is suited for residential and commercial plumbing, HVAC hydronic systems, chemical process lines, and marine or coastal installations where chloride-induced corrosion is a concern. The 316 and 316L alloy designation provides superior resistance to pitting and crevice corrosion compared to 304-series stainless. It is a standard choice for applications involving water, steam, mild acids, or salt-laden environments. The seamless construction eliminates weld seams, reducing potential leak points in pressurized service.

Key Features

• Grade 316 and 316L stainless steel construction for enhanced corrosion resistance
• Seamless manufacture eliminates weld seam vulnerability in pressurized systems
• Schedule 80 wall thickness supports higher working pressures than standard Schedule 40
• 1/4 inch pipe size with matching 1/4 inch NPT thread for direct-fit installation
• Suitable for chemical, marine, and industrial service environments

Compatibility

Designed as an OEM-style replacement and standard-fit component for 1/4 inch Schedule 80 stainless steel piping systems using NPT threaded connections.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and ASME B31 piping code requirements. Shut off system pressure and drain the line before removing or installing any threaded pipe fitting. Apply an appropriate thread sealant rated for stainless steel and the service fluid before threading the nipple into the fitting or valve body. Do not over-torque threaded connections on stainless fittings, as galling can occur and damage the threads permanently.
