This is Tamco/Toku part number 410231281 throttle valve bushing, stocked at Crowder Supply as TK-410231281. It governs how air reaches the working end of the breaker. Wear on the sealing land is the usual cause of a throttle that leaks with the trigger released.
It appears on the TPB 40 Paving Breaker breakdown. The tool itself is the Tamco/Toku TPB-40 Paving Breaker. Check it against the reference number on the diagram first; serial breaks change what fits.
Work through the rest of the assembly on the same breakdown, or start over from the full diagram library. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
