This kit supplies corrosion-resistant fittings and hardware engineered to close the rear refrigerant path and keep your front system sealed and fully functional without losing refrigerant from the rear lines.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this block-off kit stop refrigerant loss?\u003c\/h3\u003e\n\n\u003cp\u003eThe kit replaces or seals the damaged rear-service ports and evaporator feed so refrigerant cannot escape through a faulty rear circuit.
