Merit Brass 4502-350 Ss Pipe Nipple 1/8 in Sch 80 304

Product Description

The MERIT BRASS 4502-350 is a seamless stainless steel pipe nipple sized for 1/8-inch pipe, manufactured to Schedule 80 wall thickness in Grade 304/304L stainless steel. Schedule 80 construction delivers a heavier wall than standard Schedule 40, making this nipple well suited for higher-pressure and corrosion-prone applications. The Grade 304/304L dual certification means it meets both standard and low-carbon requirements, which is important in applications where welding or heat exposure is a factor. Plumbers, pipefitters, and mechanical contractors install this type of fitting in process, HVAC, and utility piping systems where corrosion resistance and pressure integrity are required.

This nipple is used in residential and commercial piping systems where stainless steel is specified for its corrosion resistance. Typical applications include steam lines, chemical transfer, food-service plumbing, and HVAC condensate or water-side connections where carbon steel would be unsuitable. The 1/8-inch pipe size fits small-diameter branch connections and instrument takeoffs. The seamless construction eliminates weld seams, which reduces failure points under cyclic pressure or temperature conditions.

Key Features

• Seamless construction — no weld seam, consistent wall integrity throughout
• Schedule 80 wall thickness for elevated pressure ratings compared to standard Schedule 40
• Grade 304/304L dual-certified stainless steel for corrosion resistance and low-carbon weldability
• 1/8-inch pipe size suits small-diameter branch, instrument, and utility connections
• UNSPSC Code 40173300 for procurement and catalog classification

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/8-inch Schedule 80 stainless steel threaded piping systems.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable codes such as the IPC or ASME B31 piping standards. Shut off and depressurize the system completely before removing or installing any threaded fitting. Use an appropriate thread sealant rated for stainless steel and the intended service fluid — avoid tape or compounds that can contaminate the line. Inspect threads carefully before installation; stainless steel is susceptible to galling, so use controlled torque and consider an anti-seize compound suitable for the service conditions.
