Grooved Equal Tees
A grooved equal tee is a ductile iron fitting with three grooved ends used to take a branch of the same size from the main line. Each end is joined with a coupling, so the branch point is built without welding and can be dismantled when needed.
It is used where sprinkler mains split in two, on loop connections and on pump headers. Sizes run from 1¼” to 12″; when a smaller outlet is required, the tee is combined with a concentric reducer.
Main Applications
- Points where sprinkler mains split
- Loop and ring main connections
- Pump suction and discharge headers
- Hose cabinet and hydrant branches
- Cooling water distribution lines
Technical Data

Material Options
| Part | Equal tee |

| Ends | Three factory-grooved ends |
| Sealing | EPDM gaskets of the couplings |
| Finish | Painted (by model) |
Which material? To take an outlet from an existing line without cutting the pipe, a mechanical tee is more practical; equal tees are preferred on new lines.
Advantages
Weld-Free Branch
- Branch point built with couplings

How to Choose?
- Set the main sizeAll three ends of the tee will be this size.
- Check the outlet needAdd a reducer if a smaller outlet is required.
- Count the couplingsPlan three couplings per equal tee.
