Merit Brass 4012-2400 Ss Pipe Nipple 3/4 in Sch 40 304

Product Description

The MERIT BRASS 4012-2400 is a Schedule 40 stainless steel pipe nipple designed for threaded pipe assemblies in plumbing, HVAC, and industrial piping systems. Manufactured from Grade 304/304L stainless steel using a welded construction method, this nipple delivers reliable corrosion resistance in a wide range of service environments. It fits 3/4 inch pipe and is suited for systems where material integrity, thread fitment, and pressure-rated Schedule 40 wall thickness are required. Licensed plumbers and pipefitters are the primary installers, though HVAC and industrial maintenance technicians also use these fittings when assembling threaded stainless runs.

This pipe nipple is appropriate for residential and commercial piping applications where Grade 304 or 304L stainless steel is specified. Common install scenarios include domestic water supply lines, process piping, steam and condensate lines, and corrosive-environment plumbing where carbon steel fittings are not suitable. The Schedule 40 wall thickness meets standard pressure ratings for general service threaded pipe systems. It is sold individually.

Key Features

• Grade 304/304L stainless steel construction for corrosion resistance in wet and chemically active environments
• Welded construction meeting Schedule 40 wall thickness requirements
• 3/4 inch pipe size with standard NPT threading for compatibility with threaded fittings and valves
• Suitable for both Grade 304 and dual-certified 304L applications
• UNSPSC Code 40173300 for procurement and catalog alignment

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4 inch Schedule 40 threaded stainless steel piping systems. Compatible with standard NPT threaded fittings, valves, and couplings rated for Schedule 40 service.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off system pressure and drain the line before removing or installing threaded nipples. Apply an appropriate thread sealant or PTFE tape rated for the service fluid before assembly. Follow local plumbing codes, including IPC requirements, for material selection and pressure system work.
