• Optimized for 1" OD tubing with 0.095" wall thickness, ensuring a perfect fit and reliable performance in tube systems.
• Enhanced weld integrity and ease of installation with a partially threaded design and 1" thread length.
• Long-term durability and corrosion resistance in demanding conditions, backed by robust material properties.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use.

Professional Applications & Engineering Value

This tube end weld nut is engineered to address critical challenges in fluid systems, hydraulic assemblies, and structural tubing applications. Crafted from 4130 alloy steel, it offers superior tensile strength and impact resistance, making it suitable for high-pressure and dynamic load environments. The left-hand thread design is essential for applications where standard right-hand threads may loosen due to rotational forces, such as in pumps, motors, and conveyor systems. With UNF fine threading and a partially threaded body, it ensures precise alignment and secure fastening on 1" OD tubing, minimizing leakage risks and maintenance downtime. This nut is ideal for industries like aerospace, automotive, and heavy machinery, where reliability and compliance with RoHS 3 and REACH standards are paramount for safety and environmental responsibility.
