Merit Brass 6506-4800 Ss Pipe Nipple 3/8 in 316 Sch 80

Product Description

The MERIT BRASS 6506-4800 is a Schedule 80 seamless stainless steel pipe nipple designed for high-pressure and corrosive-environment piping systems. Manufactured from Grade 316 stainless steel, this nipple delivers superior resistance to chlorides, acids, and caustic media compared to standard 304-grade fittings. The Schedule 80 wall thickness provides added strength over Schedule 40, making it suitable for demanding service conditions in HVAC, plumbing, and industrial process piping. Licensed plumbers and pipefitters install this fitting in systems where material integrity under stress and chemical exposure is critical.

This pipe nipple is used in residential and commercial applications requiring corrosion-resistant connections, including marine environments, chemical processing lines, food and beverage piping, and high-purity water systems. The 3/8 inch pipe size suits smaller-diameter branch lines and instrument connections. Its seamless construction eliminates weld seams, reducing potential leak points and improving pressure rating consistency throughout the fitting.

Key Features

• Grade 316 stainless steel construction resists chloride corrosion and acidic media
• Seamless manufacturing eliminates weld seams for improved pressure integrity
• Schedule 80 wall thickness rated for higher-pressure service than Schedule 40
• 3/8 inch pipe size fits standard NPT threaded connections
• UNSPSC Code 40173300 for procurement and catalog classification

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/8 inch NPT threaded pipe systems requiring Schedule 80 seamless stainless steel construction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with stainless steel threaded connections. Isolate and depressurize the system completely before removing or installing any threaded fittings. Use an appropriate thread sealant rated for stainless steel and the service media — PTFE tape or paste is commonly used on NPT threads. Avoid over-torquing, as stainless steel threads can gall; apply steady, controlled torque and use a fitting wrench rather than pipe pliers where possible.
