This high-quality lifter bleeder tool is designed to pre-bleed and remove trapped air from hydraulic lifters and tappet assemblies — ensuring smoother engine startup and preventing valve-train damage. This version is made from a durable, oil-resistant 3D-printed material for superior strength and chemical resistance.

Simply load your hydraulic lifters into the included basket, place it inside the vacuum jar, fill with clean engine oil, secure the lid, and apply vacuum (such as from a brake bleeder). You’ll see the air bubbles rise and escape, leaving your lifters fully primed and ready for installation.
