Mitigating risks in agricultural hydraulic hose applications

08 December, 2017

Consider the temperature

Temperature ratings are a critical factor when it comes to selecting a hose that is right for the job. Hot fluids that are conveyed beyond the recommended temperature limits can have a detrimental effect. Exposure to continuous high temperatures can accelerate aging leading to hoses losing their flexibility, thus accelerating the potential for failure. It is therefore imperative that hoses that can cope with high temperatures are specified.

As machines are utilised all over the world, ambient operating temperatures can vary tremendously. In certain regions day time temperatures can be very hot, therefore the hose specified needs again to be able to withstand the ambient. Essentially, it’s a twofold approach – specify for both the fluid and ambient temperatures in combination, or risk hose failure. Take for example Eaton’s GH681 and the EC881 hoses. Both have been engineered to outperform the current standards and offer capabilities up to 126degC. We should also consider low temperature threats as this also can have risks, that’s why both the GH681 and EC881 are specified to -46degC.
