Merit Brass 6504-4800 Ss Pipe Nipple 1/4 in Grade 316 Sch 80

Product Description

The MERIT BRASS 6504-4800 is a Grade 316 stainless steel seamless pipe nipple sized for 1/4-inch pipe. Built to Schedule 80 wall thickness, this nipple delivers greater pressure-handling capability than standard Schedule 40 fittings. The seamless construction eliminates a weld seam, reducing potential failure points in demanding service environments. It is used in plumbing, HVAC, and industrial piping systems where corrosion resistance and structural integrity are required. Licensed plumbers, pipefitters, and mechanical contractors are the primary installers of this fitting type.

This nipple is suited for residential and commercial piping applications where Grade 316 stainless steel is specified for its enhanced resistance to chlorides and corrosive media compared to Grade 304. Schedule 80 wall thickness makes it appropriate for higher-pressure service lines. Typical installations include chemical feed lines, steam systems, marine-adjacent plumbing, and process piping where the fitting will be exposed to moisture, mild acids, or saline environments.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in aggressive environments
• Seamless manufacture eliminates weld-seam weak points
• Schedule 80 wall thickness supports higher operating pressures versus Schedule 40
• 1/4-inch pipe size fits standard NPT threaded fittings and valves
• UNSPSC Code 40173300 for procurement and cataloging compliance

Compatibility

Designed as an OEM-style replacement or new-install fitting for 1/4-inch NPT threaded piping systems requiring Schedule 80 Grade 316 stainless steel components.

Installation Notes

Installation of pipe nipples in pressurized systems should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC codes. 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 service media and pressure. Avoid over-torquing stainless steel threads, as galling can occur without proper lubrication.
