Air Conditioning Hose SELKLIMA DN10 35 bar

The SELKLIMA DN10 35 bar air conditioning hose is a hose designed for making and repairing automotive air conditioning hoses operating with R134a refrigerant. The DN10 size corresponds to an internal diameter of 10 mm, i.e., 3/8". The hose is used in air conditioning systems of passenger cars, vans, trucks, buses, agricultural machinery, construction machinery, and special vehicles where tightness, flexibility, and resistance to A/C installation working conditions are important.

The product available in the HYDRON store as SELKLIMA DN10 35 bar air conditioning hose is a hose with an inner layer of very low permeability butyl rubber, reinforcement in the form of a single steel braid, and an outer layer made of special temperature-resistant synthetic rubber.

Air conditioning hose DN10 for R134a

SELKLIMA DN10 is a hose for transferring R134a refrigerant in air conditioning systems. It can operate with the refrigerant in gas and liquid phases, making it suitable for recreating A/C hose sections between the compressor, condenser, dryer, expansion valve, and evaporator. The DN10 / 3/8" diameter is often used in automotive and machinery installations where a higher flow is needed than in DN08 hoses.

When completing a repair, it is worth checking the entire category automotive air conditioning fittings. There you will find hoses, fittings, ferrules, connectors, and components needed to make a leak-proof air conditioning hose for a specific vehicle or machine.

Why must an air conditioning hose have low permeability?

In an A/C system, the tightness of the hose has a direct impact on cooling efficiency. The inner layer made of butyl rubber limits the permeation of the refrigerant through the hose wall. This is very important because a slow loss of refrigerant often does not result in an immediate, visible leak. Symptoms only appear over time: weaker cooling, the need for more frequent air conditioning service, pressure drop, or oiling around the fitting.

That is exactly why random rubber hoses should not be used for air conditioning. A standard technical hose may look similar, but it does not necessarily have a barrier limiting R134a permeation. The SELKLIMA DN10 hose is designed for air conditioning systems where tightness, temperature resistance, and compatibility with PAG oil are important.

Steel braid in the SELKLIMA DN10 hose

The reinforcement in the form of a single steel braid improves the stability of the hose when operating under pressure and increases mechanical resistance compared to light hoses without such reinforcement. This is important in the engine compartment, where the air conditioning hose operates near vibrations, temperature changes, and vehicle structural components. The braid helps maintain the shape of the hose and limits the risk of excessive stretching during operation.

However, this does not mean that the hose can be used as a typical hydraulic hose. The SELKLIMA DN10 air conditioning hose was designed for R134a refrigerant and PAG oil, not for working with hydraulic oil in cylinder, pump, and distributor installations. In power hydraulics, separate hydraulic hoses selected for the pressure, medium, and hydraulic fittings must be used.

Working temperature in A/C systems

An air conditioning hose operates under varying temperature conditions. In the engine compartment, it may be exposed to high ambient temperatures, while at the same time, there are sections in the refrigeration system with different thermal parameters. The product description states a range from -30°C to +125°C, while the technical parameters of the card indicate from -30°C to +100°C with the possibility of temporary operation up to +125°C.

During installation, avoid routing the hose directly next to the exhaust manifold, turbocharger, accessory belts, fan, and sharp edges. Even a temperature-resistant hose requires correct routing. If the hose rubs against a metal component or operates on too tight a bend, it may be damaged despite having the correct catalog parameters.

Selecting fittings for the DN10 air conditioning hose

To make a complete air conditioning hose, you need fittings tailored to the DN10 size and appropriate crimping ferrules. Air conditioning fittings differ from classic hydraulic fittings. They are designed to work with refrigerants, compressor oil, and for crimping A/C hoses. They require an appropriate ferrule and a correct crimp.

When selecting fittings, it is worth going to the category air conditioning hose fittings. There are straight, angled, service fittings, and elements used in the repair of air conditioning hoses in cars and machines.

Crimping ferrules for the DN10 hose

The crimping ferrule must be selected according to the diameter and design of a specific hose. In air conditioning, it is not enough to select a ferrule based solely on the DN10 internal diameter. The outer diameter of the hose, the type of reinforcement, and the type of fitting are also important. A ferrule that is too loose can cause a leak, and one that is too tight can damage the inner layer of the hose.

When assembling a hose, it is worth checking the section air conditioning hose ferrules. These are the components needed to permanently connect the fitting to the hose. For the DN10 hose, the ferrule selection should be made for the specific type of SELKLIMA hose, and not for a random hose of a similar diameter.

Where is SELKLIMA DN10 used?

The DN10 air conditioning hose is used in A/C hose repairs in passenger cars, vans, trucks, agricultural tractors, combine harvesters, excavators, loaders, buses, and special vehicles. It proves itself where the factory hose has been chafed, the fitting has corroded, the rubber has cracked, or it needs to be recreated in a non-standard length.

In the workshop, the DN10 hose is often chosen for sections with a higher flow. When replacing, it is best to compare the old hose after removal, check the diameter, type of fittings, routing of the installation, and mounting method. A section that is too short will operate under tension, and one that is too long may rub against vehicle components.

The SELKLIMA hose vs. other air conditioning hoses

Air conditioning hoses differ in design, wall thickness, braid type, outer diameter, and crimping method. SELKLIMA DN10 with a steel braid is not an automatic replacement for every DN10 hose. Before replacing, check whether the fittings, ferrules, and routing method correspond to the design of a given hose.

If a different type of A/C hose is needed, you can compare the category SELKLIMA air conditioning hose and other hoses available in the air conditioning section. The selection should always be based on the actual system, and not just on the similar appearance of the hose.

Comparison with the Continental DN10 hose

In some repairs, you can consider another type of DN10 air conditioning hose, but it should not be treated as a direct replacement without checking the parameters. For comparison, the CONTINENTAL DN10 air conditioning hoseis available. Before choosing, you must compare the outer diameter, type of reinforcement, recommended ferrules, fittings, and crimping method.

Differences between hoses are particularly important when repairing air conditioning in vehicles where fittings have limited installation space. Even a slight change in the outer diameter of the hose may require a different ferrule or change the way the hose is routed in the engine compartment.

Most common mistakes when selecting a DN10 air conditioning hose

The most common mistake is selecting a hose based solely on the 10 mm internal diameter. In air conditioning, the hose design, braid type, compatibility with R134a refrigerant, PAG oil, and ferrule fit are equally important. The second mistake is using a fuel or hydraulic hose as a replacement for an air conditioning hose. Such a hose may not provide adequate tightness for the refrigerant.

The third problem is a bending radius that is too small. A hose routed on a sharp bend can restrict flow and deteriorate faster. The fourth mistake is crimping the fitting without the correct ferrule. The fifth problem is failing to account for vibrations and engine movement. The air conditioning hose should have a natural route, without twisting or stretching the fittings.

Hose sold by the meter

The SELKLIMA DN10 air conditioning hose is sold by the meter, so you can order the length needed for a specific repair. Before cutting, it is worth planning the hose routing in the vehicle and including a margin needed for bends and fitting assembly. A section that is too short will strain the fittings, and one that is too long can create unnecessary loops and rub against machine components.

When making a hose for a specific vehicle, it is best to prepare the old hose as a template. This allows you to recreate the length, positioning of fittings, exit angles, and mounting method. In air conditioning, the precision of the hose manufacturing is important, as even a small leak causes a gradual loss of refrigerant.

Why buy the SELKLIMA DN10 hose at HYDRON?

HYDRON supplies hoses, fittings, ferrules, and accessories for the repair of automotive and machinery air conditioning systems. Thanks to a wide offer, you can choose not only the hose itself but also the components needed to make a complete A/C hose. This is a convenient solution for workshops, machine services, and customers who want to repair an air conditioning hose technically correctly, and not with a random replacement.

When making a selection, it is worth preparing a photo of the old hose, the diameter, the type of fittings, information about the vehicle, and the length of the required section. This makes it easier to select the correct hose, ferrules, and fittings, and also reduces the risk of leaks after installation.
