Gr8LOK 8046 Mech Tee - Grooved Outlet

The Mechanical Tee Grooved Outlet is a high-performance branch fitting designed to create a grooved outlet directly from an existing pipe without the need to install a full tee. Ideal for fire protection, HVAC, and mechanical services, it provides a fast, efficient solution for adding larger branch connections within grooved piping systems.

Manufactured from durable ductile iron, the mechanical tee is secured to the pipe using a bolted housing and gasket arrangement, forming a strong, pressure-responsive seal. A hole is cut into the pipe to create the outlet, allowing installation without removing or replacing pipe sections—making it particularly suitable for retrofit work, system extensions, and on-site modifications.

 
Supplied with a grooved outlet connection, this fitting enables direct integration into grooved systems, maintaining consistency across the installation while supporting efficient flow through the branch line.
