【Stainless Steel Can】The AC flush tool is made of a thickened stainless steel canister, which is excellent in compressed air, without leaks, and more durable than those made of aluminum. 【Easy-to-Use HVAC Tool Kit】Fill your a/c flush canister with light AC flush material (not included), then tighten the fittings to the canister, connect to your air compressor (not included), and turn on the valve switch and air pump.
