About Crosses

Cross pieces join four pipe ends in one plane, turning a continuous line into two opposing branches. All four ports are female threads to ISO 7-1, with sizes from Rp 1/4 up to Rp 3. The material is black malleable cast iron B350-10, hot dip galvanised.

What matters when choosing

• Thread 1 and thread 2: Rp 1/4, Rp 3/8, Rp 1/2, Rp 3/4, Rp 1, Rp 1 1/4, Rp 1 1/2, Rp 2 or Rp 3 as female threads. The nominal size follows the continuous main line, not the smaller branch.
• Thread standard: ISO 7-1. The parallel female Rp thread mates with a taper male R thread, the seal is made in the thread itself and needs a sealing compound.
• Material: black malleable cast iron B350-10 design symbol A. It carries high mechanical load and is stated for an operating temperature range from -20 °C to 300 °C.
• Surface: the items are hot dip galvanised, which allows use in damp surroundings and outdoors.

Typical applications

• Distribution nodes in compressed air ring mains built from threaded pipe
• Heating and hot water installations in classic pipework
• Fire water and sprinkler lines with branches to both sides
• Machine and frame construction where pipe is screwed together as a load bearing element
• Extending existing threaded pipe runs by two additional branches

The range is based on DIN EN 10242, formerly DIN 2950, with surface quality to DIN 2444. The 9 items therefore cover the common Rp sizes from 1/4 to 3 and are made in China.
