Merit Brass 4520-2400 Ss Pipe Nipple 1-1/4 in Sch 80 304

Product Description

The MERIT BRASS 4520-2400 is a seamless stainless steel pipe nipple sized for 1-1/4 inch pipe, constructed from Grade 304 stainless steel to Schedule 80 wall thickness. This nipple serves as a threaded connector between pipe sections, fittings, or equipment ports in fluid and gas distribution systems. The Schedule 80 wall provides greater pressure capacity than standard Schedule 40, making it appropriate for higher-demand service conditions. Licensed plumbers and pipefitters install this type of fitting in commercial and industrial piping systems where corrosion resistance and structural integrity are required.

This pipe nipple is suited for use in plumbing, process piping, and mechanical systems where Grade 304 stainless steel is specified for corrosion resistance. Typical applications include water supply lines, chemical-compatible fluid lines, and HVAC hydronic systems operating in corrosive or sanitary environments. The seamless construction eliminates weld seams, reducing potential leak points and supporting reliable long-term performance in demanding service conditions.

Key Features

• Grade 304 stainless steel construction for corrosion resistance in wet and chemical-exposure environments
• Seamless manufacturing eliminates weld seams for improved pressure integrity
• Schedule 80 wall thickness supports higher operating pressures versus Schedule 40
• 1-1/4 inch pipe size fits standard NPT threaded fittings and equipment ports of the same size
• UNSPSC Code 40173300 for procurement and catalog classification

Compatibility

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

Installation Notes

Installation of threaded stainless steel pipe nipples should be performed by a licensed plumber or pipefitter in accordance with applicable plumbing codes such as the IPC or local equivalent. Shut off and depressurize the affected line before removing or installing any fitting. Apply an appropriate thread sealant or PTFE tape rated for the service fluid and pressure. Avoid over-tightening, which can crack fittings or distort threads on stainless components.
