Product Formation

This Grooved Threaded Mechanical Tee is a high-performance, weld-free fitting designed for branch connections in fire protection and water supply pipeline systems. Constructed from ductile iron (QT450-10/12) with a durable red EP powder coating, it offers excellent corrosion and rust resistance, ensuring long-term reliability in harsh environments.

Featuring a combination of grooved clamp (for main pipe attachment) and internal thread (for branch pipe connection), it enables quick, tool-efficient installation—eliminating the need for welding and reducing on-site labor time. The EPDM rubber seal ensures a tight, leak-proof joint under a maximum working pressure of 2.5 MPa, complying with strict industry standards.

Available in various size combinations (e.g., DN100×50, DN80×32), it accommodates different main/branch pipe diameters and pairs with grade 8.8 high-strength bolts for secure fastening. Ideal for both new pipeline setups and system modifications, this fitting balances durability, ease of use, and safety for critical fluid transfer applications.
