Merit Brass 4002-4800 Ss Pipe Nipple 1/8 in Sch 40 304

Product Description

The MERIT BRASS 4002-4800 is a stainless steel pipe nipple designed for use in piping systems that require corrosion-resistant fittings. Constructed from Grade 304/304L stainless steel using a welded method, this nipple meets Schedule 40 wall thickness standards. The dual-grade 304/304L designation makes it suitable for both standard and low-carbon applications where weld-zone corrosion resistance is a concern. Licensed plumbers, pipefitters, and mechanical contractors typically install this type of fitting in process piping, HVAC hydronic systems, and industrial fluid handling lines where stainless is specified over carbon steel or brass alternatives.

This pipe nipple is sized at 1/8 inch pipe and fits into systems where small-diameter stainless fittings are required. Common applications include instrument connections, chemical feed lines, steam service, and potable water systems where low-carbon stainless is code-appropriate. Its Schedule 40 wall thickness provides adequate pressure-bearing capacity for most residential and light commercial service conditions. The welded construction is standard for stainless pipe nipples at this diameter and size range.

Key Features

Compatibility

Designed as an OEM-style replacement or new-install fitting for 1/8 inch Schedule 40 stainless steel piping systems.

Installation Notes

Installation of pipe nipples should be performed by a licensed plumber or pipefitter in accordance with the applicable plumbing code such as the IPC or IFGC. Shut off and depressurize the system before threading or replacing any fitting. Use appropriate thread sealant rated for stainless steel and the specific service medium. Do not over-tighten threaded stainless fittings, as galling of the threads can occur.
