No! The pressure ratings vary for all types of hoses—they differ based on their construction, material, size, and intended use. That’s why each hose has its own unique pressure rating.

Yes! The pressure rating of air hoses can change over time. That’s because hoses don’t stay in perfect condition forever. For instance, factors like wear and tear, bending, material degradation, and exposure to high temperatures or UV light can all cause the pressure rating to drop.

The pressure rating of air hoses is tested by manufacturers using specialized machines. These machines pump compressed air or water into the hose, gradually increasing the pressure until the hose bursts. This value is typically printed directly on the hose, indicated in units such as PSI or bar.

No, hybrid hoses are not prone to kinking. They’re lightweight, flexible, and flat, making them much easier to handle. And even if they do get twisted, their light weight ensures you can effortlessly untangle them.

Rubber endotracheal tubes are superior to PVC ones. The rubber material is both flexible and highly durable, making rubber tubes stand out in practical use.
