Merit Brass 4502-600 Ss Pipe Nipple 1/8 in Sch 80 304 304L

Product Description

The MERIT BRASS 4502-600 is a seamless stainless steel pipe nipple sized for 1/8 inch pipe, manufactured to Schedule 80 wall thickness from Grade 304/304L stainless steel. The heavier Schedule 80 wall provides increased pressure capacity and greater corrosion resistance compared to standard Schedule 40 fittings. This nipple is suited for connecting threaded pipe runs in systems where corrosion resistance, cleanliness, or elevated operating temperatures are a concern. Plumbers, pipefitters, and mechanical contractors install this type of fitting in chemical, food service, HVAC, and industrial plumbing applications where standard steel or brass fittings are not appropriate for the service environment.

This nipple is appropriate for residential and commercial installations requiring small-bore threaded stainless connections. Typical applications include instrument lines, steam service, compressed air, and corrosive fluid systems where 304 or 304L stainless is the specified material of construction. The 304L low-carbon variant is particularly suited for welded assemblies where sensitization of the heat-affected zone is a concern, though this fitting is a threaded mechanical connection.

Key Features

• Seamless construction for uniform wall thickness and consistent pressure rating
• Schedule 80 heavy wall for higher pressure service than standard Schedule 40
• Grade 304/304L dual-certified stainless steel for broad corrosion resistance
• 1/8 inch pipe size with matching NPT thread size for standard threaded fittings
• Lightweight at 0.15 pounds — suitable for instrument and small-bore piping runs

Compatibility

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

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable IPC or IFGC requirements for the service fluid. Apply an appropriate thread sealant rated for the service — PTFE tape or anaerobic thread compound are common choices for stainless NPT connections. Avoid over-tightening threaded stainless fittings, as galling can damage threads and make disassembly difficult. Isolate and depressurize the system fully before removing or installing any threaded nipple.
