Union Elbow

A Union Elbow is a precision-engineered instrumentation tube fitting designed to connect two tubes of the same outside diameter (OD) at a 90-degree angle, ensuring a secure, leak-proof, and vibration-resistant connection. It is widely used in hydraulic, pneumatic, and instrumentation systems where a change in tubing direction is required without affecting the efficiency or integrity of the fluid or gas transfer system.

Unlike standard elbow fittings, a Union Elbow features compression connections on both ends, allowing easy installation, removal, and maintenance without the need for welding or threading. The double ferrule compression design provides superior grip and sealing performance, making it suitable for high-pressure and high-temperature applications. Its compact design helps optimize piping layouts in confined spaces while minimizing pressure loss and ensuring smooth fluid flow.

Manufactured using premium-quality raw materials and advanced CNC machining technology, our Union Elbows are known for their excellent dimensional accuracy, superior corrosion resistance, high mechanical strength, and long service life. Every fitting undergoes rigorous quality inspections and testing to ensure compliance with international standards and reliable performance in demanding industrial environments.
