Merit Brass 4008-4800 Stainless Steel Pipe Nipple 1/2 in Sch 40

Product Description

The MERIT BRASS 4008-4800 is a welded stainless steel pipe nipple sized for 1/2 inch pipe, manufactured to Schedule 40 wall thickness in Grade 304/304L stainless steel. Pipe nipples serve as short threaded connectors between fittings, valves, and piping components in fluid and gas distribution systems. The dual-grade 304/304L designation means this nipple meets both standard and low-carbon stainless requirements, providing good corrosion resistance across a range of plumbing, HVAC, and process piping applications. Plumbers, pipefitters, and mechanical contractors typically install these as close nipples, short extensions, or transition connectors in threaded assemblies.

This nipple is suited for residential and light commercial plumbing systems, hydronic heating loops, process piping, and general mechanical systems where corrosion resistance and Schedule 40 pressure ratings are required. The 1/2 inch pipe size makes it a common fit for water supply lines, compressed air distribution, and steam or condensate piping where stainless material is specified. It is appropriate for use in environments exposed to moisture, mild chemicals, or conditions where carbon steel fittings would corrode prematurely.

Key Features

• Grade 304/304L dual-certified stainless steel for broad corrosion resistance and low-carbon weld compatibility
• Schedule 40 wall thickness meets standard pressure requirements for 1/2 inch threaded piping systems
• Welded construction provides consistent dimensional integrity throughout the nipple body
• UNSPSC Code 40173300 for procurement system classification
• 1/2 inch pipe size for common threaded fitting applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2 inch Schedule 40 threaded stainless steel piping systems. Compatible with standard NPT threaded fittings, valves, and couplings of matching pipe size.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements for the system type. Shut off and depressurize the piping system before removing or installing any threaded fitting. Apply thread sealant or PTFE tape rated for the service medium to NPT threads before assembly. Do not overtighten threaded connections, as stainless steel threads are susceptible to galling.
