The Heater Core Backflush Tool (60900) from Lisle Corp. features a tip that fits 1/2″, 5/8″ and 3/4″ hose fittings.
Water pressure can be easily controlled with one hand by squeezing the handle of the heavy-duty spray gun. The insulated handle protects your hand when using hot water to flush the cooling system.
The spray gun attaches to a standard garden hose.
