AUTOOL air conditioning flush kit is designed for all types of air conditioning systems (automotive, domestic and commercial refrigeration equipment).

【How it works】Fill the flush bottle with light air conditioner cleaner (not included), then fit the connector onto the canister and tighten. The conical rubber tip can be sealed at the tube opening to prevent the solution from flowing back. Connect the assembled flush bottle to the air compressor (not included) and open the valve and air pump to flush and blow out the air conditioner.
