1/4 inch x 5-1/2 inch Stainless Steel Nipple

1/4" x 5-1/2" Stainless Steel Nipple – Threaded Connector for Corrosion-Resistant Piping Systems

The 1/4" x 5-1/2" stainless steel nipple is a precision-machined pipe segment with male NPT threads, designed for direct connection between two female-threaded components in industrial, mechanical, and plumbing systems. Manufactured from Schedule 40 stainless steel pipe, it offers durability and corrosion resistance in pressurized or chemical environments.

Technical Specifications

• Material: 304 stainless steel (UNS S30400) or 316 stainless steel if specified
• Nominal Size: 1/4 inch
• Length: 5-1/2 inches overall
• Thread Type: NPT (National Pipe Taper), conforming to ANSI/ASME B1.20.1
• Wall Thickness: Schedule 40 (standard weight)
• Manufacturing Standards: Conforms to ASTM A312/A733 for stainless pipe nipples
• Operating Pressure: Dependent on system design; commonly rated up to 300 psi in general applications

Installation Guidelines

Inspect threads prior to assembly to ensure proper fit and sealing. Use PTFE tape or thread sealant compatible with stainless steel and system media. Tighten using an appropriately sized wrench, following torque guidelines to avoid thread distortion. Always pressure-test the system post-installation in accordance with applicable codes.

Common Applications

This stainless steel nipple is commonly used in:

• Potable and non-potable water systems
• Compressed air lines and vacuum service
• Food processing and pharmaceutical environments (when 316 is specified)
• Corrosive or high-temperature service piping

Material Note

304 stainless steel provides general corrosion resistance suitable for most indoor and dry process conditions. For environments exposed to chlorides or aggressive chemicals, 316 stainless steel may be required. Confirm alloy compatibility based on system requirements.
