Health and Safety Information


Things you should know



•  The rotary unions illustrated within this catalogue should not present any hazard when correctly fitted, installed, maintained and operated within the normal conditions and parameters as outlined by the specifications provided. To ensure satisfactory performance, all unions are run-in and leakage tested before shipping. Please note that dismantling units will invalidate the warranty.


•  It is essential to use the correct hand of rotary connection thread to ensure that
the union with not unscrew (see the installation instructions for additional information). If a shaft reverses rotation while under operating conditions then the union must be locked or, preferably, a flanged connection should be used.


•  Prior to any maintenance, repair or removal, be sure to depressurize and drain
the system to avoid injury.


•  Do not exceed or combine maximums as outlined under the maximum operating
conditions for each rotary union model. When in doubt, please contact us for additional information to ensure safe, satisfactory performance. 


•  At some point, the seals in a rotary union will leak. Regular daily inspection is
recommended. Ensure that any leakages are not hazardous to personnel or equipment and be sure to fit protective guards when appropriate. Repair any leaks immediately to avoid the possibility of extensive damage. If leakages are not attended to promptly, bearing seizure is possible which can lead to flexible hose failure and potentially massive leakage. As a preventative measure for certain hazardous applications, an excess torque detector can be fitted to stop a machine before major damage occurs.


•  With oil systems, minor leakages are normal and will occur resulting from the
natural characteristics of oil which prevents the seal faces from contacting fully. 


•  Also note: for all rotary union models currently manufactured, non-asbestos
gaskets have replaced all of the compressed asbestos fibre material that was used previously. Existing units may still contain asbestos and should be handled and disposed with care according to asbestos product safety regulations.
