Merit Brass 4502-450 Stainless Steel Pipe Nipple 1/8 in Sch 80

Product Description

The MERIT BRASS 4502-450 is a seamless stainless steel pipe nipple designed for threaded piping assemblies in demanding trade applications. Built to Schedule 80 wall thickness and manufactured from Grade 304/304L stainless steel, this nipple delivers the added wall strength and corrosion resistance required in plumbing, HVAC, and industrial piping systems. The 1/8 inch pipe size suits small-bore connections where pressure integrity and material quality matter. Licensed plumbers and pipefitters typically install this fitting as part of threaded gas, water, or chemical service lines where stainless construction is specified by code or system design.

This pipe nipple is suited for residential and commercial threaded piping installations. It is commonly used in tight-space or small-bore applications such as instrument connections, gauge ports, chemical feed lines, and low-volume fluid or gas service runs. The Schedule 80 wall thickness makes it appropriate for higher-pressure service compared to standard Schedule 40 fittings. Grade 304/304L dual certification supports use in both standard and low-carbon weld-adjacent applications.

Key Features

• Seamless construction for uniform wall integrity and pressure reliability
• Schedule 80 wall thickness for higher-pressure service ratings versus Schedule 40
• Grade 304/304L stainless steel provides broad corrosion resistance in wet and chemical environments
• 1/8 inch pipe thread size fits standard small-bore threaded fittings and valves
• Dual-grade 304/304L certification supports weld-adjacent and standard service installations

Compatibility

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

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or IFGC requirements for threaded stainless fittings. Shut off and depressurize the line completely before removing or installing any threaded nipple. Use appropriate thread sealant or PTFE tape rated for the service fluid and pressure. Do not over-torque stainless threads, as galling can occur without proper lubrication or anti-seize compound on the threads.
