Straight Tee Configuration
Straight-Through Run
Two opposing flanged openings form the main straight-through piping path.
90° Branch
The third flanged opening creates a perpendicular branch connection from the main run.
Same-Size Configuration
The straight tee maintains the same nominal pipe size through the run and branch connections.
Construction Details
These 125# flanged straight tees are manufactured from grey iron castings conforming to ASTM A126 and ASTM A48.
Flanged fitting dimensions conform to ASME B16.1 and ANSI/AWWA C110/A21.10. The three-flange configuration allows the tee to be bolted into compatible piping systems for a secure and serviceable branch connection.
Why Choose a 125# Flanged Straight Tee?
Three-Way Flow Distribution
- Creates a 90-degree branch connection
- Maintains the same nominal size throughout
- Flanged connections on all three openings
- Useful for distributing flow from a main line
- Class 125 configuration
Grey Iron Construction
- Grey iron castings
- Conforms to ASTM A126 and ASTM A48
- Dimensions conform to ASME B16.1
- Also references ANSI/AWWA C110/A21.10
- Manufactured in an ISO-certified facility
Straight Tee vs. Reducing Tee
Straight Tee
A straight tee maintains the same nominal pipe size across the main run and branch connection.
Reducing Tee
A reducing tee uses a smaller branch connection than the main run to create a branch while transitioning pipe size.
