9920 vs 9920-A

Follow

9920 and 9920-A are both flexible pipes to connect the outlet of a test injector to the delivery measuring system (i.e. graduated glass tubes).

The difference is located essentially on the connecting plugs:

  • 9920 is equipped with standard quick release connectors, the same on both ends.
  • 9920-A is equipped with reinforced quick release connectors, differentiated on each end (allowing one-way flow). Each connector is made by two parts: one with spring, as a part of the pipe; the other to be mounted on the fitting (see the below picture for further details)

Can be 9920 exchanged with 9920-A?

Yes, there is no technical obstacle to use the same bracket for test injectors and mixed pipes between 9920 and 9920-A. It's up to you.

Which is the difference between 9920-B and 9920-C?

9920-B and 9920-C are not equivalent, as they allow the flow in one-way only.

To avoid the pipe to explode, double check the correct mounting to allow the flow from the test injector outlet to the measuring system.

Note: when checking, be sure that the pipe is connected to the fittings (both parts of 9920-B and both parts of 9920-C)
