What application is PCL’s Superflex Air Hose suitable for? Alternatively, you can mount them in a hose reel that can be wound up with a crank handle and mounted on a wall. You can loosely wrap the hose into loops for storage. PCL’s range of standard hoses lie flat, without bends or coils, some prefer standard air hoses because they don’t like the resistance in coiled hoses. Nylon also has excellent resistance from fuels, oils and abrasion, however offers greater heat and chemical resistance and supports a high working pressure than Polyurethane (PU), therefore is recommended for higher pressure applications. What application is Nylon hose suitable for? PU hoses have an excellent resistance to abrasion from fuel, oils and abrasion and is commonly used in medium pressure applications. PCL’s range of durable and hardwearing Polyurethane (PU) hoses are ideal for applications that require a tighter bend radius, such as in robotics and pneumatic control machinery. What application is Polyurethane (PU) hose suitable for? Many factories use coiled hoses as they spring out of the way when they are not in use. The coils are tensile and have a memory so when you let go of the hose, it shrinks back for easy storage, and leaves the work area clear of entanglements and trip hazards. The material of the hose will affect the flexibility, weight, longevity, and performance therefore you will also need to ensure that the material is suitable for your application.Īvailable in Polyurethane or Nylon, PCL’s coiled hoses are ideal for applications where space is tight. There are two types of hoses, Standard or Coiled, your application will determine which type of hose you require. You should not use the burst pressure as an indication that the hose can be used above the maximum working pressure, the burst pressure is for manufacturing test purposes only. Most hoses in the PCL range offer a 3:1 Safety Factor, this means if the hose is rated at 21 bar / 300 psi working pressure, the burst pressure will be 63 bar / 900 psi. The hose specification may also list the burst pressure, which is the maximum pressure before the hose will rupture. The maximum working pressure of the hose must be equal or greater. This will depend on the maximum pressure relevant to your air supply. The air tool manufacturer will usually list the minimum hose size on the tool’s specification. Air tools that require a larger CFM such as an ½” impact wrench will require a minimum of 10mm hose to run at full capacity. To maintain adequate airflow, you must ensure that the Hose I.D is not too small for the tools CFM requirements as this will affect your tools performance.Īir tools that require a lower 1-3 CFM such as a nail gun, usually work well with a 7mm hose. determines the capacity of air the hose can carry.Ĭommon hose sizes are 7 mm (1/4 in), 8 mm (5/16 in), 10 mm (3/8 in) and 13 mm (1/2 in). The hose O.D will depend on the thickness of the hose and reinforcement layer, while the hose I.D. However, hose size refers to the hose I.D., rather than the hose O.D. Hose specifications usually list both the hose Outer Diameter (O.D.) and the Internal Diameter (I.D.). We recommend that you use a longer air hose rather than an extension lead with an air compressor, as the voltage drop from using an extension lead can cause the motor to overheat which will eventually lead to the compressor motor burning out. For example, a carpenter working at the same bench all day using a nail gun will only need a small hose length, whereas a tyre fitter who needs to manoeuvre around large vehicles while using an impact wrench, will require a longer hose length. To minimise the risk of a pressure drop, you should never use a longer hose than you need. When selecting an air hose, you should always consider your application and total distance between the compressor system and where you will be using the air tool and how much movement you will need. Here is a quick and easy guide on the factors you should consider in order to select the right air hose for your application. To make the most out of your pneumatic tools, choosing a quality hose is essential to ensure stable air pressure. How to choose the right compressed air hose for your application
