How to Choose the Right Pressure Rating for Air-Operated Hoses

When it comes to air-operated systems, it's essential to identify the correct pressure rating for hoses. To do this, you need to know the optimal air flow rate (SCFM) for your pneumatic tool or equipment. Suction hoses don't require heavy construction since the air or dry materials being transported are much lighter than liquids or solids. PCL offers a range of standard hoses that are flat and have no bends or coils, as well as high-performance TPE compound hoses that look and feel like rubber but are lighter.

Oil, steam, chemical, fire and marine hoses should only be used by qualified personnel and should be tested. The SuperFlex hose is great for low temperatures down to -40°C, but it's best to avoid high temperatures as the hose may become too soft. The safest approach is to select a compressed air hose based on the pressure of the compressed air system. For example, a carpenter who works all day on the same bench with a nail gun will need a smaller hose than a tire fitter who needs to maneuver around large vehicles with an impact wrench.

The manufacturer usually marks the industrial rubber hose with its nominal working pressure before assembling it. The hose specification can also indicate the burst pressure, which is the maximum pressure before the hose breaks. To learn more about flexible air hoses and their minimum inner diameter, you can download a reference table of flexible hoses by type of pneumatic tool and air consumption (PDF). Before using them, make sure to check for cuts or holes in the hoses and don't leave them lying around after use.

The material of the outer part of the hose is approved by BS EN 12365-1 (construction standard for weatherstripping on doors and windows), so it offers excellent weather resistance properties, oil resistance and softness for easy handling and greater comfort. Hoses manufactured according to Rubber Manufacturers Association (RMA) standards have a basic safety factor. PCL also has a range of hose assemblies with couplings and adapters. Investing in a PCL hose for pneumatic tools saves time and money since you don't need expensive crimping equipment; just plug it in and you're good to go.

For a hose to provide electrical continuity, the cable must properly contact the hose fittings.
