Merit Brass 6504-1000 Pipe Nipple 1/4 in Sch 80 316 Ss

Product Description

The MERIT BRASS 6504-1000 is a seamless stainless steel pipe nipple designed for demanding piping applications where corrosion resistance and pressure integrity are essential. Built to Schedule 80 wall thickness and manufactured from Grade 316/316L stainless steel, this nipple delivers the additional wall strength required in high-pressure or corrosive fluid systems. The 316/316L dual-grade material offers superior resistance to chlorides and oxidizing environments compared to standard 304 stainless. Licensed plumbers and pipefitters install this type of fitting in commercial plumbing, industrial process piping, and mechanical systems where standard carbon steel or brass fittings would be unsuitable.

This pipe nipple is sized for 1/4 inch pipe and is well suited for use in chemical handling lines, steam service, marine environments, food processing piping, and HVAC hydronic systems where corrosion resistance is a priority. Its seamless construction eliminates weld seams, reducing potential failure points under pressure cycling or thermal stress. The Schedule 80 designation makes it appropriate for higher-pressure service conditions compared to Schedule 40 alternatives.

Key Features

• Grade 316/316L seamless stainless steel construction for superior corrosion resistance
• Schedule 80 wall thickness for high-pressure service applications
• 1/4 inch pipe size with matching 1/4 inch thread size
• Seamless construction eliminates weld-zone vulnerabilities
• Dual-certified 316/316L material suitable for low-carbon weld requirements

Compatibility

Designed as an OEM-style replacement or new-install fitting for 1/4 inch Schedule 80 stainless steel piping systems. Compatible with standard NPT threaded fittings and valves in the same pipe size and schedule.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC and ASME B31 piping code requirements. Shut off and depressurize the system completely before removing or installing any threaded pipe fitting. Use an appropriate thread sealant rated for stainless steel and the intended service fluid. Avoid over-tightening, which can stress the threads on smaller-diameter nipples.
