Mackay Universal Water Hoses - The ideal replacement for your cooling system When it comes time to overhaul your cooling system, replacing your universal water hoses is essential. Mackay replacement universal water hoses are designed with long service life in mind. Suitable for plain water or automotive coolant, Mackay coolant hoses are resistant to heat which makes them great for withstanding harsh under bonnet temperatures and coolant temperatures without becoming fatigued, cracked or split. Mackay universal water hoses are also ozone resistant. 'Ozone cracking' is a type of damage that occurs to vulnerable rubbers over time, resulting in hairline cracks and splits which eventually grow to create a leak, however with ozone-resistant rubbers this is simply not an issue. Mackay coolant hoses are also resistant to electrochemical degradation, a type of fatiguing and weathering that is caused by the break-down of hoses as a result of electrical reactions between your coolant and the metal parts of the engine.
