The parts effected by this change are:

20580-00 (the flowmeter kit will include 4 of each new jet as well as 1 strainer – reducing strainers included by 3, as they are no longer required for insertion/removal)

20581-01 (new jet supplied instead of old version)

20581-03 (new jet supplied instead of old version)

20581-05 (new jet supplied instead of old version)

20581-07 (new jet supplied instead of old version)

Any pre-assembled flow monitoring system manifolds that also include a flowmeter kit with the jets. (e.g. 20644-00, 20643-00, 20642-00, 20641-00, 20634-00, 20633-00, 20632-00, 20631-00)
