Merit Brass 6504-250 Ss Pipe Nipple 1/4 in Sch 80 316 316L

Product Description

The MERIT BRASS 6504-250 is a Schedule 80 seamless stainless steel pipe nipple sized for 1/4-inch pipe. Manufactured from Grade 316/316L stainless steel, this nipple offers strong resistance to corrosion and elevated-temperature service, making it suitable for demanding fluid and gas piping applications. The seamless construction eliminates a weld seam, which reduces potential leak points and improves pressure integrity. Plumbers, pipefitters, and mechanical contractors install this type of nipple where a short threaded extension or close connection is needed in a stainless steel piping system.

This pipe nipple fits into residential and commercial plumbing, HVAC hydronic systems, industrial process piping, and chemical or marine environments where 316/316L stainless is specified for its chloride and corrosion resistance. At 1/4-inch pipe size with NPT-compatible threading, it connects standard Schedule 80 fittings, valves, gauges, and instrumentation ports. It is a common component in close-coupled connections within tight mechanical spaces.

Key Features

• Grade 316/316L stainless steel construction for superior corrosion resistance in harsh or wet environments
• Seamless pipe body eliminates weld seams, supporting higher pressure integrity
• Schedule 80 wall thickness for added strength over standard Schedule 40
• 1/4-inch pipe size fits standard NPT fittings, valves, and instrumentation connections
• Lightweight at 0.1 pounds, suitable for tight or weight-sensitive installations

Compatibility

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

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable IPC or ASME B31 piping codes. Shut off and depressurize the piping system fully before removing or installing any threaded nipple. Use appropriate thread sealant or PTFE tape rated for the service fluid and temperature. Do not over-torque threaded stainless steel fittings, as galling can occur; hand-tighten and finish with a pipe wrench using controlled force.
