Are you looking for a special pipe or tubing developed specially to connect four sections of pipe or tubing at 90-degree viewpoints to form a cross-shaped junction? If yes then, you need an Equal Union Cross. It is engineered with ‘Precision’ with ‘Perfection’ for enhanced ‘Durability’ and delivery of ‘High-performance’ in the piping system.
This pipe fitting comprises a few major components. These include equal-sized ports on all four ends, ensuring uniform flow distribution across each connection. Typically, Equal Union Cross is commonly used in pneumatic, hydraulic, and fluid handling systems.
They are manufactured using stainless steel, or high-score polymers. . Above all, Equal Union Cross is a piping component that plays a major role in creating branch lines or complex piping layouts wherein consistent flow and reliable sealing are essential. At Tubotech, a top Equal Union Cross manufacturer in Mumbai we offer you high-quality piping and tubing components of world-class quality that delivers ‘High-Performance’ at affordable pricing.
