Industrial Hose Crimp Diameter Calculator

The KuriCrimp Industrial Hose Crimp Calculator provides the appropriate crimp diameter based on your hose and fitting dimensions. Enter your measurements in inches, and results will be provided in both inches and millimeters. It is highly suggested to use KOA Couplings and Ferrules, as they are specially designed to work together with Kuri Tec^®, Tigerflex™ and Alfagomma^® Industrial hose.

Crimp Diameter Formula

Crimp Diameter Formula = Hose OD - Hose ID + Shank OD + (2 x Ferrule/Sleeve Wall Thickness) + [ ( - Compression Percentage) x Hose OD - Hose ID) /100]

Important Notes:

Please consult KuriCrimp Catalog section pages on Determining Crimper Capacity and Coupling Fitting OD’s when entering the optional Maximum Coupling OD Dimension (mm). The largest typical Maximum Coupling OD encountered during assembly can be used to help inform crimper suggestions if considering a new crimper purchase.
KuriCrimp crimper standard die size recommendations are to be used as a guide. Various KuriCrimp crimpers have specific ranged standard die size and die type options. Certain hose crimping applications require very specific crimps and/or specific, possibly even custom, dies to achieve a proper crimped hose assembly. Always use the proper relevant crimping guide tables, instructions, and crimper user guides to ensure the correct die size and die type are selected. For further industrial hose assembly crimping considerations, please also refer to the KuriCrimp Catalog section on Determining Crimper Capacity.
Crimp diameter calculations are to be used as a guide. Hydrostatic pressure testing of assemblies is recommended to ensure proper coupling retention. Always refer to the NAHAD Industrial Hose Assembly Guidelines for latest hose assembly and testing industry practices.
