This is Chicago Pneumatic part number P005171, which also shows up as 3310104302 lever pin, stocked at Crowder Supply as CP-P005171. It governs how air reaches the working end of the rivet buster. Wear on the sealing land is the usual cause of a throttle that leaks with the trigger released.
Crowder’s breakdowns list this part on the CP 4608 4611 Rivet Buster and CP 4181 Duler Duser Rivet Buster. Worth matching the reference number on the diagram against your own machine before you order the same part number can sit in more than one position.
