Stainless Steel Threaded Crosses
A stainless threaded cross is an AISI 304 cast fitting with four female-threaded ends that joins four pipes at a single point on a stainless line. It solves a node that would need two tees with one body.
It is used in process water distribution nodes, test and calibration rigs and lines where measuring points are grouped. It is supplied in 9 sizes from 1/2″ to 4″.
Main Applications
- Process water distribution nodes
- Test and calibration rigs
- Grouping measuring, drain and air release points
- Multi-way distribution in food lines
- Water distribution in marine environments
- Laboratory supply lines

Which material? Since all lines at a distribution node carry the same medium, the cross is chosen in the same stainless grade as the pipe; a 316 cross should be preferred on a 316 line.
Advantages
Node in One Body
- One cross instead of two tees and a nipple
Grouped Measuring Point
- Gauge, sensor and drain at the same point
Resistance Without Coating
- The stainless surface resists corrosion inside the node too
Flexible Use
- Spare ends can be plugged and opened later
Construction and Design Features
- Four Rp female-threaded ends on two perpendicular axes
- Common flow chamber at the centre
- Investment-cast stainless body (depending on model)
- ISO 4144 pressure ratings
Send the cross size and quantity; we will also prepare stainless plugs for spare ends.
How to Choose?
- Determine the number of connectionsUse a cross for four directions and a tee for three.
- Measure the sizeAll four ends are the same size; add stainless reducing bushes for other sizes.
- Match the grade to the lineIf the pipe is 316, the cross should be 316 too.
- Check the pressure limitUse the applicable value of 20 / 16.5 / 15 bar according to the operating temperature.
