DTC‑GROOVED CROSS-DI Series
DTC supplies ductile iron grooved cross fittings for fire protection piping systems. Designed for four-way branch connections, our grooved crosses provide reliable sealing, fast installation, and durable performance in sprinkler, HVAC, and industrial piping applications.
A fire protection grooved cross fitting is a four-way mechanical pipe fitting designed to connect four sections of piping at a single intersection point. It allows fluid flow to be distributed in multiple directions while maintaining a secure grooved mechanical connection.
Grooved crosses are widely used in complex fire sprinkler layouts where multiple branch lines are required. Compared with fabricated welded cross fittings, grooved cross fittings provide faster installation, easier maintenance, and improved flexibility.
DTC supplies ductile iron grooved crosses for fire protection applications, manufactured with high-strength ductile iron bodies and reliable gasket sealing systems. They are suitable for commercial buildings, industrial facilities, warehouses, and infrastructure projects requiring dependable fire suppression piping.
Provides a convenient solution for connecting four pipeline directions in sprinkler and industrial piping layouts.
The grooved connection design allows installation without welding, reducing labor time and construction costs.
Ductile iron provides:
Rubber gasket sealing ensures leak-resistant performance under working pressure.
Suitable for complex fire protection piping arrangements requiring multiple branch connections.
