Ordering by number: this is Y10212090, the Tamco/Toku throttle valve cap. It governs how air reaches the working end of the chipping hammer. Wear on the sealing land is the usual cause of a throttle that leaks with the trigger released.
It appears on the THH 1 2 3 4 Chipping Hammer and THA 1 2 3 4 Chipping Hammer breakdown. Check it against the reference number on the diagram first; serial breaks change what fits.
If you need the parts around it, the full diagram library has the full breakdown library, and the Tamco/Toku tool range covers the machines themselves. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
