We know that you can distinguish the hose of hydraulic fittings. What's more challenging is to determine the type of hose that may need to be replaced when carrying out maintenance in various systems in daily use. Today's Xiaobian will introduce how to judge the hose quality of hydraulic fittings.

Give each hose a project number, your process can start before the hose is put into use, and using a digital system of hoses and fittings will make it easier to replace the hose later, and the system can track the service life of the hose and its exact location.

Know the marking, all hydraulic hoses are marked with type, size, pressure grade and curing date, do not replace the old hose with new hose with the rated value lower than the use value, if you use the unmarked hose, they are really old, and the manufacturer has been required to mark the hydraulic hose for many years.

Determine the size and understand what the size marked on the hose represents. The inner diameter or "inner diameter" measures the hole diameter, the outer diameter or "outer diameter" measures the total outer diameter of the hose. The OD is the information matching the accessories, and consider the different wall thickness.
