A must-have accessory for Cummins, International, PACCAR, and Volvo Closed-End DOCs.
The adapter plate channels more vacuum to the upper cleaning chamber to compensate for the reduced flow through the small filter outlet. This adapter will prevent particulate from escaping out the top of the TrapBlaster ™ during cleaning.
For newer larger DOCS that have trouble rotating in the TrapBlaster, you will need the FSX Tilted DOC Adaptor Plate ™
Note: Cleaning these type of DOCs may cause particulate to escape out of the top of the TrapBlaster, so it is recommended that you don't clean these unless this adapter plate is used.
Note: Cleaning these closed-end DOCs is accomplished by using only the lower air nozzle.
