Nissens Automotive expands its climate comfort system replacement parts offering with a first-fit air conditioning hose solution.
To function correctly and operate at its optimum efficiency, all of the elements within every vehicle system need to be in good condition and working in harmony with all the others. This is particularly true of the air conditioning, which, although it utilises certain common properties, such as electrical power from the battery and drive from the engine, in many ways is a standalone system that works independently of many of the vehicle’s other systems.
Due to its central role within the A/C system, the compressor is often referred to as its heart, but the hoses, which connect all of the components together and transport the oil/refrigerant mixture around the sealed loop, are also vital for the system to function correctly, so can perhaps be compared to its arteries.
Annually checking the condition of the A/C system is an important job for the independent workshop and to enable them to carry out the work proficiently and to use premium quality replacement components, aftermarket specialist Nissens Automotive, is on hand to help them with both expert instruction and the required parts.
As a leader in thermal management solutions, Nissens has the specialist knowledge required to understand the requirements of the A/C system and therefore the quality of the components needed to support its correct operation.
In addition, being totally dedicated to the needs of the aftermarket, its ambition is to provide the industry with a holistic approach, not only in terms of the quality of the parts it supplies and the technical support it makes available, but also when it comes to the breadth of its offering.
With this in mind, Nissens is pleased to announce the introduction of replacement A/C hoses into its growing product portfolio. This launch provides a premium quality solution to the need for reliable, high performance and long-lasting replacements, that fulfil the functional demands of the A/C system.
Looking for trouble
One of the most important aspects of A/C service is to check the condition of the entire sealed loop, not just around the joints to the system’s major components like the compressor, condenser and heat exchangers, but also along the length of the hoses, whether they are sections of solid tube or flexible hose.
Telltale signs of potential A/C hose problems/refrigerant leaks include oily, dust-attracting areas because the oil remains on the surface and dust and dirt then stick to it, so soiling on the hose, joins or surface are clear signs of a leak problem.
In addition, the flexible rubber-based sections can become porous, causing the gradual escape of the refrigerant. Older and higher mileage cars should therefore undergo particularly careful inspection in these areas.
Finally, mechanical damage, even if only light in nature, or vibrations, can both expose the hose to risk or the loosening of joints and subsequent refrigerant loss. Cracks, bends and perforations cannot be repaired.
Testing for leaks
If a potential leak is detected, a proper leak test procedure should be undertaken, including a long-term test using a nitrogen-based solution and leak sensor support.
This best practice principle is important because the refrigerant and lubricant, which is necessary for the A/C system’s efficient operation, needs to be in the correct ratio. System leaks can easily disrupt this balance. In addition, these leaks can potentially cause contamination from moisture or foreign particles.
Should a failing joint, crack or split become apparent, the A/C hose will need to be replaced, which also provides the opportunity to flush out the old mixture and replenish it with new oil and refrigerant, something that should also be part of a standard A/C service. However, this will also require the appropriate pulled vacuum process to remove moisture and facilitate the final charge.
So as you can see, A/C hoses are a vital component. What’s more, they remain relevant irrespective of the vehicle’s powertrain. They are used in the heat pump systems associated with electric vehicles, as much as they are in traditional combustion engine systems.
With an initial range covering approximately 25-30 per cent of the European passenger and light commercial vehicle parc, the Nissens A/C hose range is designed to offer a premium quality aftermarket product featuring a meticulous design, fully compatible with vehicle layouts and modern refrigerants. The hoses are thoroughly tested to ensure a leak tight, efficient and long, trouble-free service life. Combined with the company’s first-fit inclusive parts policy, this should tick all the boxes for the independent workshop.
