When you have a truckmount with 2½” outlet pipe, you can use the AH140 2½” male starter Cool Cuff  to connect  2½” hose directly to the machine. The 2½” vacuum hose must have an AH142 2½” female swivel Cool Cuff  to connect to the starter cuff.


If you want to connect  2” hose to the machine use the AH148 2½” external reducer Cool Cuff and a AH120 2” male Cool Cuff . The 2” vacuum hose must have an AH122PS 2” female swivel Cool Cuff  to connect to the 2” male Cool Cuff.

Connecting 2½” Truck Mount Port to 2”  Vacuum Hose

Here is the standard application of the 2½” Swivel Cool Cuffs to connect two sections of  2½” vacuum hose. An AH143
2½” male Cool Cuff is connected to
one hose and an AH142 2½” female swivel Cool Cuff is connected to the other hose. The smooth bore creates less turbulence and resistance to the air flow increasing the velocity of the air flow at the tool.

AH153 – 2½” Cool Y Assembly is used in the “4 to the Door” set up with a 2½” hose for the run from the door to the tool. (A 2” hose can be added later in the run for flexibility at the tool.)

Two 2” hoses from the truck mount must each have AH120 2” male cuffs to connect to the two AH122PS 2” female swivel connectors. The one 2½” hose to the wand will have an AH142  2½” female swivel cuff to connect to the AH140 2½”male starter connector on the AH151 2½” Cool Y assembly.
