Gates Hydraulic Descriptions
Descriptions for Gates Hydraulic Hose, Couplings, and Adapters were designed to simplify the identification of Gates hydraulic products. Hose and coupling descriptions are an effective reference when determining Gates hydraulic part numbers.
Hydraulic hose catalog descriptions are the simplest we could devise. The letters are abbreviations of a complete description and are all easy to learn. For SAE hoses the basic letter is "C" and it is a substitute for 100. The number which follows the "C" designates the SAE specification. (Example: C1A means SAE 100R1A; we dropped the "R" to keep the descriptions short.) Additional hoses have descriptions which are abbreviations of their construction or use.
For a detailed listing of Gates Hydraulic Hose Catalog Descriptions, refer to Hydraulic Hose Selection Guide.
This chart shows:
Standard Industry Specifications (if applicable), Temperature Range, Use, Tube & Cover Stock , Construction, Hose Page Number, Hose Description, Dash Size
NOTE: SAE 100R series hose listed in this catalog meet or exceed those specifications as described in SAE J517.
In applications where the electrical conductivity of a hydraulic assembly is a factor, Gates C7SNC and C8SNC hose is non-conductive per SAE J517 as tested per SAE J343.
CAUTION:
Working Pressure
Working pressure of the application should always determine selection of hose. Used up to the recommended working pressure, hose will provide normal service life before replacement is required.
Maximum Working Pressure
Maximum working pressure of any hose line must also include any spikes or pressure surges. This may require a gauge reading since pressure relief valve settings can be initially overridden.
Minimum Burst Pressure
When new, the hose described in this catalog will meet or exceed the minimum burst pressure shown in the hose specification tables. However - as with any hose in the industry - after hose has been impulsed for a length of time, the minimum burst pressure will decrease from the figure shown in the specification tables.
Temperature Ranges
The temperature ranges specified for specific hoses refer to recommended limits of fluids being conveyed or ambient temperatures. Exceeding these limits will cause degradation of material compounds and reduced hose service life.
