- Optimized tube compatibility designed specifically for 3/4" OD tubing with 0.065" wall thickness
- Secure partial threading providing 1 1/8" of engaged threads while allowing for proper weld placement
- Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial use
- Fine UNF thread spacing delivering superior clamping force and leak prevention in fluid systems
Professional Applications & Engineering Value
This specialized left-hand thread tube end weld nut solves critical reverse-rotation challenges in hydraulic systems, pneumatic assemblies, and rotating machinery where standard right-hand threads would naturally loosen. The 4130 alloy steel construction provides exceptional tensile strength and fatigue resistance, while the UNF fine threading and Class 2B fit ensure precise, leak-free connections in high-pressure applications. Engineered specifically for 3/4" OD tubing, this partially threaded design allows for optimal weld placement without compromising thread integrity, making it ideal for aerospace, automotive, and heavy equipment industries where vibration resistance and reliability are paramount.
Specification Summary & Compliance
This tube end weld nut features 7/16"-20 UNF left-hand fine threading with Class 2B thread fit per UNF standards, providing precise dimensional accuracy. The 1 1/8" thread length and 1 3/8" height ensure proper engagement depth. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental compliance for industrial applications worldwide. Designed specifically for use with 3/4" OD tubing having 0.065" wall thickness.
