Threaded Cross
Threaded Cross Manufacturer & Supplier
A Threaded Cross is a four-way pipe fitting with one inlet and three outlets arranged at 90-degree angles. It features internal threads (female) on all four ends, allowing for easy and leak-proof connection of threaded pipes without welding. Threaded Cross fittings are typically used in high-pressure, small-bore piping systems.
