Merit Brass 4548-350 Stainless Steel Pipe Nipple 3 in Sch 80

Product Description

The MERIT BRASS 4548-350 is a seamless stainless steel pipe nipple designed for use in high-pressure and corrosion-resistant piping systems. Manufactured from Grade 304/304L stainless steel with a Schedule 80 wall thickness, this nipple delivers the structural integrity required in demanding industrial, commercial, and mechanical applications. The seamless construction eliminates weld seams, reducing potential failure points under pressure or cyclic stress. At 3 inches pipe size, it fits standard NPT threaded connections and is handled primarily by licensed plumbers, pipefitters, and mechanical contractors working on fluid-handling or process piping systems.

This pipe nipple is suited for use in commercial and industrial plumbing, HVAC hydronic systems, chemical transfer lines, food-service piping, and other applications where corrosion resistance and pressure integrity are required. Grade 304/304L dual-certified stainless steel makes it appropriate for environments exposed to moisture, mild acids, or sanitary requirements. The Schedule 80 wall thickness supports higher operating pressures compared to Schedule 40, making it a common choice in mechanical rooms, boiler rooms, and process piping installations.

Key Features

• Seamless construction eliminates weld seams for greater pressure integrity
• Grade 304/304L dual-certified stainless steel for broad corrosion resistance
• Schedule 80 wall thickness rated for higher-pressure service than Schedule 40
• 3 inch pipe size with standard NPT threading
• Suitable for sanitary, chemical, and mechanical piping applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3 inch Schedule 80 NPT threaded stainless steel piping systems.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter in accordance with applicable IPC or ASME B31 piping codes. Shut off and depressurize the line before removing or installing any threaded fitting. Use an appropriate thread sealant or tape rated for stainless steel and the service fluid. Avoid over-tightening, which can stress the threads on stainless fittings and lead to galling.
