Merit Brass 4502-001 Stainless Steel Pipe Nipple 1/8 in Sch 80

Product Description

The MERIT BRASS 4502-001 is a seamless stainless steel pipe nipple designed for threaded pipe assemblies in plumbing, HVAC, and industrial piping systems. Manufactured from Grade 304/304L stainless steel and rated at Schedule 80 wall thickness, this nipple delivers the higher pressure ratings and corrosion resistance required in demanding service environments. The 1/8 inch pipe size suits small-bore connections common in gas lines, instrumentation, and fluid distribution headers. Licensed plumbers and pipefitters install this type of fitting where standard carbon steel is unsuitable due to corrosion exposure or fluid compatibility requirements.

This pipe nipple is suited for residential and light commercial plumbing, HVAC refrigerant and condensate piping, and industrial process lines where 1/8 inch threaded connections are required. Its seamless construction eliminates weld seams, making it appropriate for higher-pressure small-bore applications. The 304/304L dual certification allows use in both standard and low-carbon weld-adjacent installations.

Key Features

• Grade 304/304L stainless steel construction for corrosion resistance in wet or chemically active environments
• Seamless manufacturing eliminates weld seams for improved pressure integrity
• Schedule 80 wall thickness provides greater pressure rating versus Schedule 40
• 1/8 inch pipe size with matching 1/8 inch thread size for direct threaded assembly
• UNSPSC Code 40173300 for procurement and catalog classification

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC code requirements. Shut off and depressurize the pipe system fully before removing or installing any threaded fitting. Apply an appropriate thread sealant rated for the service fluid and pressure before assembly. Do not over-torque stainless steel fittings, as galling on the threads can cause permanent damage.
