What information is needed to select a hose?
Hose selection does not start with diameter and pressure alone. The fluid, temperature, application, dimensions, pressure/vacuum and end connections must be defined together. STAMPED is a reminder used to gather this in…

How are inside diameter, outside diameter and overall length defined?
Inside diameter denotes the flow path, outside diameter the outer envelope, and overall length the assembly length between two defined references. These three dimensions cannot be used interchangeably. The cut length of…

The difference between working, test and burst pressure
Working pressure refers to the service limit, test pressure to a defined test condition, and burst pressure to a separate strength test. The burst value is not a usable working pressure; no single universal ratio is ass…
-
How are fluid and ambient temperature distinguished?
Fluid temperature is the condition the hose sees from the inside, and ambient temperature the condition it sees from the outside. Both are assessed in selection. Continuous operation, short-term peak, start-up and clean…

Selection differences between suction and discharge applications
A discharge hose must be suitable for internal pressure, while a suction hose must be suitable for the external-internal pressure difference in the application. A high positive working pressure rating is not a guarantee…
