Hydraulic hose and fittings are designed and made to DIN Specifications. This means that you can’t match one manufacturer’s hose with another manufacturer’s fittings. All hydraulic hoses have different external specifications and all hydraulic fittings are a different size and design. Only hose and fittings that have been tested through 500,000 pulse cycles without a failure comply with DIN specifications. Hydraulink Canberra tests its hydraulic hose for 1,000,000 cycles. In other words, cheap hydraulic hose is not matched to any fittings. Injury or damage caused by a failed hose may not be covered by insurance or WC.
