A straight tee, also known as a tee fitting, has three outlets arranged in a “T” shape, while a lateral tee has two outlets arranged at a 90-degree angle to the main pipe. The straight tee is used when a 90-degree connection is not needed, whereas a lateral tee is used to create a 90-degree branch or lateral connection.
There are mainly two types of lateral tee – equal lateral tee and reducing lateral tee. The equal lateral tee has the same-sized outlets, while the reducing lateral tee has different-sized outlets.
A lateral reducing tee is a type of lateral tee that has different-sized outlets. This fitting is used when the main pipe is larger than the branch pipe, and the flow needs to be reduced as it branches out.
A lateral tee, also known as a branch tee, is a type of pipe fitting used in a piping system to create a branch or lateral connection from the main pipe to a side pipe or a branch pipe. The lateral tee has one inlet and two outlets at a 90-degree angle from the main pipe.
