3.21.7 Designation of threaded connections.

To make clear what sealing type of threaded connection is provided we denominate them according to standards ISO 7/1 and ISO 228/1 as follows.

3.21.7.1Threaded connection Rp (example Rp 1/2)

If no flattened sealing face is provided we call the connection Rp according to ISO 7/1. This connection has to be sealed in the thread.

The plugs or pipe connections must be provided with conical thread according to ISO 7/1 external thread (example ISO 7/1 - R1/2).

3.21.7.2Threaded connection G (example G 1/2).

If the threaded connection is provided of a flattened sealing face we call it G according to ISO 228/1.

This connection can be sealed by a gasket. The plugs or pipe connections must be provided with a sealing collar and cylindrical external thread according to ISO 228/1 (Example ISO 228/1 - G1/2). Plugs or pipe connections provided with conical thread according to ISO 7/1 external thread (example ISO 7/1 - R1/2) can also be used.
