Grooved Mechanical Tee for Fire Fighting

Grooved Mechanical Tee for Fire Fighting

Product Overview

The Grooved Mechanical Tee is a specialized branch connection fitting designed for the rapid modification and expansion of fire protection piping systems. Unlike standard tees that require cutting the main pipe, the Mechanical Tee allows for a branch outlet to be added to an existing pipeline by drilling a single hole. This fitting is essential for connecting sprinkler drop lines, cross-overs, and auxiliary branches to main headers without compromising the structural integrity of the main line. Manufactured from high-strength ductile iron and coated in fire-resistant red epoxy, it is a critical component for UL/FM listed fire suppression networks.

Key Features and Benefits

• Rapid Installation: Installs in minutes with a simple drill and wrench; no welding, threading, or cutting of the main pipe is required.

• Cost-Effective Branching: Significantly reduces labor and material costs compared to cutting the pipe and installing a standard grooved tee.

• High-Pressure Integrity: Designed to withstand the high pressure surges typical in fire fighting systems, with a robust housing that resists deformation.

• Versatile Outlet Options: Available with Threaded (NPT/BSP) or Grooved outlets to match the specific requirements of the branch piping.

• Corrosion Resistance: Finished with a heavy-duty red epoxy coating (RAL 3000) to prevent rust in wet and dry sprinkler environments.

Applications

The Grooved Mechanical Tee is widely utilized in life-safety and industrial fire suppression systems:

• Automatic Sprinkler Systems: Connecting drop lines to main distribution pipes in commercial and industrial buildings.

• Standpipes & Hose Systems: creating outlets for fire hose connections on vertical risers.

• Fire Pump Rooms: Branching auxiliary lines for pressure gauges, test headers, and circulation relief.

• Underground Fire Mains: Tapping into main water feeds for building supply.

• Retrofits & Modifications: Adding new sprinkler heads or zones to existing piping without draining the entire system.
