Merit Brass 6504-600 Ss Pipe Nipple 1/4 in Sch 80 316 316L

Product Description

The MERIT BRASS 6504-600 is a Schedule 80 seamless stainless steel pipe nipple sized for 1/4-inch pipe, manufactured from Grade 316/316L stainless steel. Schedule 80 wall thickness provides greater pressure tolerance compared to standard Schedule 40 fittings, making this nipple suitable for demanding fluid and gas transfer applications. The seamless construction eliminates a weld seam, which reduces potential failure points in high-pressure or corrosive service. Plumbers, pipefitters, and HVAC technicians install this type of fitting when system design calls for threaded connections in corrosive or sanitary environments.

This nipple is suited for residential and commercial piping systems where corrosion resistance is a priority, including chemical process lines, marine plumbing, food-service installations, and applications involving saltwater or chlorinated fluids. The 316/316L dual-grade designation means it meets both standard and low-carbon requirements, supporting weld-adjacent installations where sensitization is a concern. It is appropriate for use in Schedule 80 systems requiring 1/4-inch NPT threaded connections.

Key Features

• Grade 316/316L seamless stainless steel construction for superior corrosion resistance
• Schedule 80 wall thickness for higher pressure ratings versus Schedule 40
• Seamless pipe body reduces weld-related failure risk
• 1/4-inch NPT thread size for standard threaded pipe system integration
• Dual-grade 316/316L designation supports weld-adjacent and low-carbon applications

Compatibility

Designed as an OEM-style threaded fitting for Schedule 80 stainless steel piping systems using 1/4-inch NPT connections in plumbing, HVAC, and industrial process applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC codes for threaded pipe assemblies. Shut off and depressurize the line before removing or installing any threaded fittings. Use an appropriate thread sealant rated for stainless steel and compatible with the system media. Avoid over-torquing threaded stainless connections, as galling can occur on stainless-to-stainless thread engagement.
