A Reducing Union is a precision-engineered instrumentation tube fitting designed to securely connect two tubes of different outside diameters (OD) while ensuring a leak-proof and vibration-resistant joint. It is widely used in hydraulic, pneumatic, and process instrumentation systems where a change in tubing size is required without compromising system performance or flow efficiency.

Unlike a standard union that joins tubes of the same size, a Reducing Union allows a smooth transition between larger and smaller tubing, making it an ideal solution for modifying existing systems, adapting equipment connections, or optimizing fluid and gas flow. Its double ferrule compression design provides excellent grip on the tubing, preventing leakage even under high-pressure and high-temperature operating conditions.

Manufactured using premium-quality raw materials and advanced CNC machining technology, our Reducing Unions offer exceptional dimensional accuracy, superior corrosion resistance, high mechanical strength, and excellent sealing performance. Every fitting is precision-machined and thoroughly tested to meet international quality standards, ensuring dependable operation in demanding industrial environments.

Available in a wide range of tube size combinations, pressure ratings, thread configurations (where applicable), and material grades, our Reducing Unions are suitable for critical applications across industries such as oil & gas, petrochemical, power generation, pharmaceuticals, food processing, chemical plants, marine, and process instrumentation.
