Merit Brass 6504-500 Ss Pipe Nipple 1/4 in Sch 80 316 316L

Product Description

The MERIT BRASS 6504-500 is a seamless stainless steel pipe nipple designed for use in high-pressure and corrosion-sensitive piping systems. Manufactured from Grade 316 and 316L stainless steel, this nipple meets the demands of applications where chloride exposure, chemical contact, or elevated temperatures are a concern. It is built to Schedule 80 wall thickness, which provides greater pressure capacity compared to standard Schedule 40. The 1/4 inch pipe size and NPT threading make it compatible with standard fittings and valves used by licensed plumbers, pipefitters, and mechanical contractors across industrial, commercial, and process piping installations.

This nipple is suited for use in plumbing, chemical processing, marine, food service, and HVAC piping applications where standard carbon steel or Schedule 40 fittings would be inadequate. The 316 and 316L dual-grade designation means it can be used in both standard and weld-adjacent applications without sensitization concerns. The seamless construction eliminates weld seams that could be a point of failure under cyclical pressure or corrosive conditions. Installers working on compressed air, steam, chemical feed, or process fluid lines will find this nipple appropriate for tight-space connections requiring a reliable, corrosion-resistant short-run fitting.

Key Features

• Grade 316 and 316L dual-certified stainless steel for corrosion resistance in demanding environments
• Seamless construction eliminates weld-seam failure points under pressure cycling
• Schedule 80 wall thickness rated for higher working pressures than Schedule 40
• 1/4 inch NPT-threaded ends for compatibility with standard trade fittings and valves
• Suitable for chemical, marine, food service, and industrial process piping

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 80 stainless steel threaded piping systems with 1/4 inch NPT connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or ASME B31 piping codes. Shut off and depressurize the line completely before removing or installing any threaded nipple. Apply an appropriate thread sealant rated for the service fluid and pressure range. Do not over-torque threaded connections, as stainless steel threads are susceptible to galling.
