About Elbow connector

The angled distributor to figure 221 brings three female threads together in one corner and replaces the usual combination of elbow and tee at a branch point. The range covers Rp 1/2 to Rp 2 and is stated for operating temperatures from -20 °C to 300 °C.

What matters when choosing

• Thread 1 and thread 2: Rp 1/2, Rp 3/4, Rp 1, Rp 1 1/2 or Rp 2, all female. The nominal size of the connected pipework decides the size.
• Standard thread ISO 7-1: the Rp female thread works against a taper male thread. If the mating part follows a different standard, the joint will not seal.
• Material: black malleable cast iron B350-10, design symbol A. It takes high mechanical load but needs corrosion protection outdoors.
• Temperature: -20 °C to 300 °C is stated for the range. Pipe, sealing compound and mating part have to cover the same window.
• Design: the angled distributor places three ports in one corner. Where a straight run with a branch is needed, a tee belongs in that position.

Typical applications

• Distribution and collection points in compressed air lines made from threaded pipe
• Corner branches in water and utility lines in plant engineering
• Heating and hot water installations around the manifold
• Pipe routing on machine frames where the line turns a corner
• Maintenance and rebuilding of existing threaded pipe networks

All five sizes are made from black malleable cast iron B350-10, the thread follows ISO 7-1 and the fitting range DIN EN 10242, formerly DIN 2950. Surface quality follows DIN 2444, country of origin is China.
