Stainless Steel Press Fit Tee for Branch Pipe Connections
The stainless steel press fit tee is designed to create reliable branch connections in double-press pipe systems. This product range includes equal tee and reducing tee options, helping installers build straight branch lines, size transitions and compact pipe layouts with consistent connection quality.
Made from 304 / 316L stainless steel, the tee supports corrosion resistance, clean media delivery and long-term piping performance. It is suitable for building water supply, HVAC, industrial piping and prefabricated pipe modules where stable branch connections are required.
Press Fit Tee Options
This product combines the main non-threaded tee options in one range:
- Equal Tee: three ports have the same nominal diameter
- Reducing Tee, Branch Smaller Than Run: the branch outlet is smaller than the main run
- Reducing Tee, Branch Larger Than Run: the branch outlet is larger than the main run for special routing needs
By combining these options in one product range, the press fit tee helps project teams select the right branch connection without switching between separate product pages.
Equal Tee vs Reducing Tee
An equal tee is used when the main pipe and branch pipe share the same size. It is suitable for standard branch lines in water supply, HVAC and industrial stainless steel piping systems.
A reducing tee is used when the branch pipe size differs from the main run. The branch may be smaller or larger depending on the flow design, equipment layout and installation requirements. This structure helps installers connect different pipe sizes while keeping the system compact and organized.
Key Advantages
- Reliable branch connection: suitable for creating clean and stable branch lines in double-press pipe systems.
- Equal and reducing options: supports both same-size and size-transition branch connections.
- Stainless steel material: works with stainless steel pipes to support corrosion resistance and clean media delivery.
- Installation efficiency: press-fit installation helps reduce on-site complexity compared with welding or threading.
- Prefabrication friendly: standardized tee options support modular piping work and repeatable installation quality.
