Merit Brass 4502-500 Stainless Steel Pipe Nipple 1/8 in Sch 80

Product Description

The MERIT BRASS 4502-500 is a seamless stainless steel pipe nipple designed for use in high-pressure and corrosion-resistant piping systems. Built to Schedule 80 wall thickness and manufactured from Grade 304/304L stainless steel, this nipple delivers reliable performance in demanding fluid and gas service applications. The 1/8 inch pipe size makes it suited for tight-space connections and small-bore instrumentation or utility lines. Licensed plumbers, pipefitters, and HVAC technicians install this type of nipple when system design calls for stainless construction to resist oxidation, chemical exposure, or elevated temperatures.

This pipe nipple is used in residential and commercial plumbing, HVAC, and industrial process piping where 1/8 inch threaded connections are required. Its Schedule 80 wall thickness provides greater pressure tolerance compared to standard Schedule 40 fittings. The seamless construction eliminates weld seams, reducing potential leak points in critical service lines. Typical applications include instrument sensing lines, gas pilot supply lines, chemical feed systems, and steam service connections.

Key Features

• Seamless construction eliminates weld seams for improved pressure integrity
• Grade 304/304L stainless steel for corrosion resistance in wet and chemical environments
• Schedule 80 wall thickness for higher pressure ratings versus standard Schedule 40
• 1/8 inch NPT thread size suitable for small-bore instrument and utility connections
• Dual-certified 304/304L material meets both standard and low-carbon stainless requirements

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 ASME B31 piping codes. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant rated for stainless steel and the intended service fluid. Do not overtighten threaded connections, as this can stress the fitting body or damage mating threads.
