Coil hoses as the name suggests are hoses which assume a coil shape. They are very similar in appearance to telephone cords which connect headsets to telephone bases. Coil hoses are characterized by a series of expandable loops which increase length when pulled. Once a user is done using coil hoses, the hose resumes its original size position. This feature of coil hoses makes them compact and very easy to store.
Coil hoses are the best types of hoses for applications that involve a lot of movement. It is however important to note that they function best when they are limited to small areas. The average length of coil hoses is 10 yards or 9.5 meters. It is however possible to get a coil hose of any specific length. The best coil hose applications are those which don’t require a lot of stretching. This is because coil hoses work best in their original size/length. Stretching coil hoses can result in a lot of resistance making them very difficult to work with.
Coil hoses are used for two main applications i.e. carrying air and carrying water. Water coil hoses are convenient for residential applications i.e. watering gardens or patio areas (areas with many plants). Coil air hoses are used alongside equipment such as air compressors in residential and commercial applications.
One of the most common coil hoses are garden hoses. The hoses are usually characterised according to the material that makes them. Common examples of coil hoses are PVC and Polyurethane (PU) coil hoses.
1. PVC coil hoses
These coil hoses are made of Polyvinyl chloride (PVC) as the name suggests. PVC coil hoses are the perfect solution if you want easy and clean garden watering. PVC coil hoses are preferred by many people for gardening because of their ability to stretch to any required length after which they bounce back to their normal size allowing neat easy storage. It is important to note that the best PVC coil hoses are patented ensuring superb performance and quality.
Some of the main characteristics of PVC coil hoses includes; their bounce back capabilities and UV resistance. PVC coil hoses are also lightweight and durable. They can handle operating pressure up to 300 psi or 20 bar which is more than adequate for residential applications. It is also important to note that PVC coil hoses are available in numerous colours and a variety of accessory options.
2. Polyurethane (PU) coil hoses
As the name suggests, these coil hoses are made from Polyurethane (PU). Polyurethane is a form of plastic applied to fabrics among other materials to make them durable and attractive at the same time. Polyurethane (PU) coil hoses are therefore durable compared to most regular coil hoses in the market today. It is important to note that most PU coil hose manufacturers use resistance technologies to increase the lifespan and resilience of polyurethane coil hoses. For this reason, they are the best garden hoses if you are looking for hoses which will last a lifetime.
In summary, it is important to note that there are many other types of coil hoses. The above types are however the most common.
