safety information tm quick disconnect couplings safety information for eaton coupling and swivel products 1.0 general instructions 1.1 scope the scope of this safety bulletin is to warn against improper selection use installation etc of eaton coupling/swivel products 1.2 distribution a copy of this safety bulletin should be distributed to all individuals responsible for using and/or selecting eaton coupling/swivel products 1.3 fail-safe design all systems and equipment for failsafe operation such that failure of any component does not result in personal injury and/or property damage 1.4 user responsibility it is the sole responsibility of the user to select and determine that the eaton product is compatible with the end use application the user is responsible for reading and following this safety bulletin as well as any instructions or literature on the eaton product being used the user must provide necessary product warnings for eaton couplings/swivel products used with systems or equipment to the operators of the systems or equipment 1.5 usage with other manufacturers products when using eaton coupling/swivel products with other manufacturers adapters hoses etc do not exceed the lowest pressure rating of any of the components being used or rupture may result 2.0 selection of eaton couplings/swivels 2.1 pressure ensure that the maximum operating pressure of the system or equipment does not exceed the rated operating pressure of the eaton coupling/swivel product or rupture may result 2.2 fluid compatibility verify that all components seals metals etc are compatible with the fluid being conveyed failure to do so may result in high speed fluid discharge and/or leakage of fluids which may be flammable toxic at extreme temperatures or otherwise harmful 2.3 temperature ensure that the maximum operating temperature of the system or equipment does not exceed the rated operating temperature of the eaton coupling/swivel product including seals or rupture may result 2.4 coupling/swivel size use properly sized couplings swivels such that there is not a large pressure drop across them thus avoiding system damage due to excessive heat generation or failure of internal components 2.5 sleeve lock use sleeve locks or threaded couplings where there is the possibility of accidental disconnection failure to utilize sleeve locks or threaded couplings in these applications may result in hose whip expelled components high speed fluid discharge system damage or leakage of fluids which may be flammable toxic at extreme temperatures or otherwise harmful 2.6 connect or disconnect under pressure if connection and/or disconnection of couplings under pressure is a requirement only use couplings designed for connection/disconnection under pressure failure to utilize this type of coupling in that application may result in hose whip expelled components high speed fluid discharge and/or system damage be certain not to confuse the rated operating pressure with the rated connect/disconnect under pressure 2.7 environment ensure that eaton couplings/swivels are compatible with the surrounding environment the surrounding environment may be heat salt water moisture chemicals and the like failure to protect against an adverse environment may cause system damage premature failure and/or leakage of fluids which may be flammable toxic at extreme temperatures or otherwise harmful 2.8 external loads avoid any external loads such as side loads tensile loads vibration etc failure to do so may result in accidental disconnection premature failure system damage and/or leakage of fluids which may be flammable toxic at extreme temperatures or otherwise harmful 2.9 welding brazing extreme heating of plated products above +450°f 232°c such as welding brazing baking etc where the plating is burned off may result in the release of deadly gases 3.0 installation of eaton coupling swivel products 3.1 inspection of product prior to installation ensure that the eaton product meets all of the requirements of the system and/or equipment it is to be used on ensure you have the correct part number function test the coupling by connecting it with a mating half and function test the swivel by rotating the sleeve the function test should result in smooth non-binding operation or premature failure may result 3.2 cleanliness use end caps and plugs to reduce the risk of system contamination or damage to critical sealing surfaces failure to do so may result in leakage of fluids which may be flammable toxic at extreme temperatures or otherwise harmful caps and plugs are not a secondary seal unless explicitly noted 3.3 location place eaton couplings and swivels in a safe location such as not to expose the user to personal injury slippage tripping falling etc during installation connection disconnection and maintenance 4.0 product maintenance a maintenance schedule should be put in place to ensure that eaton couplings and swivels are functioning properly 4.1 inspection visually inspect to ensure that there is no leakage cracked components corrosion build-up contamination build-up wear etc if any abnormality is encountered the coupling or swivel should be replaced immediately this page is part of a complete catalog which contains technical and safety data that must be reviewed when selecting a product 8
