Merit Brass 4502-400 Pipe Nipple 1/8 in Sch 80 Ss 304

Product Description

The MERIT BRASS 4502-400 is a seamless stainless steel pipe nipple sized at 1/8 inch, manufactured to Schedule 80 wall thickness in Grade 304/304L stainless steel. Schedule 80 construction delivers a heavier wall than standard Schedule 40 fittings, making it suitable for higher-pressure service lines and corrosive environments. Grade 304/304L dual certification covers both standard and low-carbon applications, reducing the risk of sensitization in welded assemblies. This nipple is installed by licensed plumbers, pipefitters, and HVAC technicians working on steam, water, chemical, or gas distribution systems where corrosion resistance and pressure integrity are required.

This fitting is commonly used in residential and light commercial plumbing, HVAC, and industrial piping systems where stainless steel is specified for corrosion resistance or sanitary requirements. The 1/8 inch size suits instrument connections, pilot lines, gauge ports, and low-flow branch takeoffs. Seamless construction eliminates the weld seam, which improves pressure consistency and reduces potential leak points in demanding service conditions.

Key Features

• Seamless construction for uniform wall thickness and improved pressure integrity
• Schedule 80 heavy wall for higher-pressure and more demanding service environments
• Grade 304/304L dual-certified stainless steel for broad corrosion resistance and weld compatibility
• 1/8 inch pipe size suits instrument ports, gauge connections, and small-diameter branch lines
• UNSPSC Code 40173300 for procurement and catalog classification

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/8 inch Schedule 80 threaded stainless steel piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code or ASME B31 piping standards. Shut off and isolate the system and relieve all pressure before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the service fluid before making up the joint. Avoid over-tightening, which can crack fittings or distort threads on small-diameter nipples.
