Air pressure acting on this piston opens and closes the gun when you pull and release the trigger, so a damaged piston shows up as sluggish or incomplete triggering.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGenuine Graco air piston\u003c\/li\u003e\n\u003cli\u003eFits the cylinder of Fusion AP and Fusion PC guns\u003c\/li\u003e\n\u003cli\u003eGraco sells matching piston o-rings (248135) and piston shaft o-rings (248134) in packs of 6\u003c\/li\u003e\n\u003cli\u003eReplace when the piston is scored or cracked\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 15B203\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Graco\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDescription:\u003c\/strong\u003e Piston\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eParts list reference:\u003c\/strong\u003e Ref. 15\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eListed in Graco's Fusion AP (manual 309550) and Fusion PC (manual 3A7314) spray gun parts lists.
