The equal cross is one kind of the pipe cross, just like a equal tee, the equal cross means all the 4 ends of the cross are in same diameter.

- Dimensions applicable to crosses NPS 24(DN 600) and smaller.
Common types of pipe tee
A pipe tee is a type of fitting that has a T shape and is used to join two or more plumbing pipes.
- Equre tee (or straight tee), means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee.
- Reducing tee is a type of pipe fitting in which the branch port size is smaller than the ports of the run.
- Barred tee is used in pipelines that are pigged.
- Lateral tee has a 45 degree branch from a pipeline.
- Pipe cross is a fitting that used in the place where four pipes meet with the same diameter include:
- Reducing cross used for connecting four pipes, the main pipes with the same size, but the dimensions of the branch diameter is smaller than the main pipes.
- Equal cross in the place where four pipes meet with the same diameter.
- Forged Tee Fittings are pipe fittings that be formed mainly by forging.
Size range: 1/2 to 72 inches
Pressure: SCH5 to SCH160

Features of Pipe Tee:
- There are three female openings in a T shaped pipe tee.
- There are straight pipe tees which have the same size openings.
- Reducing pipe tees have one opening of different size and two openings of the same size.
- There are sanitary pipe tees which are used in waste lines. These kind of pipe tees have a curved branch which is designed for a clean out plug. They are used to prevent obstruction of waste.
- A cross pipe tee has four equal sized female openings.
- A wing pipe tee has lugs to fasten the fitting to a wall or stud.
- A compression pipe tee uses compression fittings on two or more ends.
- A test pipe tee has a threaded opening. This opening is used in conjunction with a threaded plug for a clean-out opening on a drain pipe.
