Merit Brass 4502-300 Stainless Steel Pipe Nipple 1/8 in Sch 80

Product Description

The MERIT BRASS 4502-300 is a seamless stainless steel pipe nipple rated for Schedule 80 service in 1/8 inch pipe size. Manufactured from Grade 304/304L stainless steel, this nipple delivers the corrosion resistance and wall thickness required for demanding plumbing, HVAC, and industrial piping applications. The seamless construction eliminates weld seams, reducing the risk of failure under pressure cycling or corrosive media. At 0.072 pounds, it is a compact fitting suited for tight inline connections in both new construction and retrofit work. Licensed plumbers and pipefitters are the primary installers.

This pipe nipple is used in residential and commercial piping systems where corrosion resistance and pressure integrity are priorities. Schedule 80 wall thickness makes it appropriate for higher-pressure service compared to standard Schedule 40 fittings. Typical install scenarios include chemical feed lines, steam service, compressed air headers, boiler trim piping, and any application where stainless steel is specified over carbon steel or brass to resist corrosion from fluids or ambient environment.

Key Features

• Seamless construction eliminates weld-zone weakness for improved pressure integrity
• Grade 304/304L dual certification suits both standard and low-carbon welding applications
• Schedule 80 wall thickness provides increased pressure rating versus Schedule 40
• 1/8 inch pipe size fits compact inline connections in tight plumbing layouts
• Stainless steel material resists corrosion from water, steam, and mild chemical exposure

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 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 in accordance with applicable IPC and IFGC codes. Shut off and depressurize the line before removing or installing any threaded fitting. Use an appropriate thread sealant rated for stainless steel and the service media. Avoid over-tightening, which can crack fittings or distort threads on small pipe sizes.
