PAHs or PAH, short for Polycyclic Aromatic Hydrocarbons, is a group of organic compounds that is composed of multiple aromatic rings.

The pressure resistance of rubber hose varies depending on the structure of the reinforcement layers and the combination of dimensions and thickness. Manufacturers design optimized structures to meet requirements and avoid issues such as hose rupture or leakage, which could lead to serious situations like machinery downtime.

O-Rings: O-rings are circular elastomer rings with a round cross-section, typically fixed in grooves and compressed by two or more components to create a sealing interface. They are commonly used in places like oil cylinders, chain links, pipelines, and pistons. In addition to general industrial O-rings, LeeKuma provides customers with material selection for automotive O-rings according to the JASO standard.

Incorrect or inappropriate selection or use of rubber hoses can result in injuries or property damage. To avoid these situations and ensure the effective transportation function of rubber hoses, you can generally select the appropriate hose based on usage, diameter, working pressure, and the clamping method of the metal connectors at both ends

With over 45-year experience in the rubber industry, LeeKuma often receives inquiries from customers on how to choose the right rubber.
