Time of issue:2026-03-07

In the field of high-pressure hydraulic hoses, there are various designations. Misunderstanding the definition and implication of these designations can easily lead to wrong selection and application of hoses. Here, we sort out how to correctly understand the specifications and models of high-pressure hydraulic hoses.

// What are Specifications and Models? //

These are two closely related but distinct concepts used to identify and describe product characteristics; they are often used together to denote a set of codes or labels that comprehensively reflect a product’s nature, performance, quality, and other indicators.

Specifications (spec) refers to a product’s concrete technical parameters, performance criteria, and physical attributes—such as dimensions, weight, capacity, power, material, purity, and resolution.

Model refers to the unique identifier assigned by the manufacturer to a particular product design or series, typically composed of letters, numbers, or a combination thereof. It denotes a specific product line or version and is used to distinguish products with different designs, functions, or configurations.
