Crosses
Types of Cross Fittings
Cross fittings provide a four-way branching connection used to route fluid or air to multiple lines from a central junction. They are selected when the layout requires multiple branches and port alignment is important.
- Cross fittings used to split flow into multiple directions from a single junction.
- Cross fittings selected to match port standards and sealing methods across all branches.
- Cross fittings used where compact multi-branch routing is required.
For simpler branch connections, see Tees.
Key Selection Criteria for Cross Fittings
- Port size and thread/seal compatibility across all four ports.
- Pressure rating and temperature requirements.
- Flow requirements and routing needs for each branch line.
- Installation clearance and access for tightening and service.
- Material compatibility with media and environment.
Cross fittings should be selected to maintain consistent sealing and rating across every branch connection.
Frequently Asked Questions
When should I use a cross fitting instead of a tee?
Use a cross fitting when you need a four-way junction with multiple branch lines. Use a tee when only one branch is required off the main line.
What should I confirm for port size and sealing method?
Confirm the thread type, sealing method, and size requirements for each connected line so all ports match the system standard.
How do cross fittings affect system pressure drop?
Any junction can influence flow and pressure drop depending on routing and branch demands. Match the fitting size and flow requirements to avoid restriction in critical lines.
