• Broad media compatibility for use with air, argon, natural gas, nitrogen, oil, oxygen, steam, and water systems
• Enhanced installation efficiency with fully threaded design that provides maximum engagement and adjustment flexibility
• Regulatory compliance assurance meeting ASME B1.20.1, B31.1, and B31.3 standards for engineering safety and performance
• Environmental responsibility with RoHS 3 compliance, containing lead exemption for copper alloys while maintaining material performance

Professional Applications & Engineering Value

Engineered for extreme-pressure industrial systems, this precision-machined 360 brass pipe nipple delivers critical performance where failure is not an option. The rolled thread fabrication creates work-hardened threads with superior fatigue resistance, significantly reducing the risk of stress cracking under cyclic loading conditions. This fully threaded NPT design ensures maximum engagement depth for high-pressure sealing in applications ranging from compressed gas systems to high-temperature steam lines. The brass construction provides excellent corrosion resistance against water, oils, and industrial gases while maintaining non-sparking properties crucial for oxygen service and natural gas applications. With compliance to multiple ASME standards, this component integrates seamlessly into engineered systems requiring certified safety margins and predictable performance under extreme operating conditions.
