Merit Brass 4502-250 Stainless Steel Pipe Nipple 1/8 in Sch 80

Product Description

The MERIT BRASS 4502-250 is a seamless stainless steel pipe nipple rated for Schedule 80 service. Built from Grade 304/304L stainless steel, it delivers corrosion resistance suited to demanding plumbing, HVAC, and industrial piping applications. The 1/8 inch pipe size and NPT threading make it a standard close or short nipple for connecting fittings, valves, and equipment in tight spaces. This component is specified by licensed plumbers, pipefitters, and HVAC technicians where schedule 80 wall thickness and stainless material grade are required by system design or code.

This nipple is used in residential and commercial piping systems where corrosion resistance and pressure-rated performance are required. Typical install scenarios include boiler trim, chemical service lines, steam piping, compressed air distribution, and process fluid connections. The 1/8 inch pipe size suits instrument connections, gauge ports, and small-diameter branch lines. Grade 304/304L dual certification allows use in both standard and low-carbon weld-adjacent applications.

Key Features

• Seamless construction — no weld seam for uniform wall integrity under pressure
• Grade 304/304L dual-certified stainless steel for broad corrosion resistance
• Schedule 80 wall thickness for elevated pressure service
• 1/8 inch NPT thread size for standard fitting and valve compatibility
• UNSPSC Code 40173300 — pipe nipple category

Compatibility

Designed as an OEM-style replacement or new-install component for 1/8 inch Schedule 80 stainless steel piping systems using standard NPT threaded fittings and valves.

Installation Notes

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