Merit Brass 4520-3600 Ss Pipe Nipple 1-1/4 in Sch 80 Gr 304

Product Description

The MERIT BRASS 4520-3600 is a Schedule 80 seamless stainless steel pipe nipple sized for 1-1/4 inch pipe, manufactured from Grade 304 stainless steel. Pipe nipples of this type serve as short threaded connectors between fittings, valves, and equipment in fluid and gas piping systems. The Schedule 80 wall thickness provides greater pressure capacity and mechanical strength compared to Schedule 40, making this nipple appropriate for demanding service conditions. Grade 304 stainless steel offers reliable corrosion resistance across a broad range of media. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical installers.

This pipe nipple is suited for use in commercial and industrial plumbing, process piping, HVAC hydronic systems, and other applications where corrosion resistance and pressure integrity are required. The 1-1/4 inch pipe size fits standard NPT threaded connections at that diameter. Seamless construction eliminates the weld seam, reducing potential weak points under cyclic pressure or vibration loads commonly encountered in mechanical room installations.

Key Features

• Grade 304 stainless steel construction for corrosion resistance in wet and chemical-exposure environments
• Schedule 80 wall thickness for elevated pressure ratings versus standard Schedule 40
• Seamless construction removes weld-seam variability, supporting consistent pressure performance
• 1-1/4 inch pipe size with standard NPT threading for broad fitting compatibility
• Suitable for plumbing, hydronic, and industrial process piping applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/4 inch NPT threaded piping systems requiring Grade 304 stainless steel, Schedule 80 seamless pipe nipples.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with the International Plumbing Code or applicable local code. Shut off and depressurize the system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the service media to all NPT threads before assembly. Do not overtighten threaded connections, as stainless steel threads are susceptible to galling.
