HEALTH & SAFETY

The Rotary Unions shown in this leaflet should not present any hazard when correctly fitted

and used.

To ensure satisfactory performance, every Rotary Union is run-in and leakage tested

before despatch.

It is essential to use the correct hand of rotary connection thread to ensure the Rotary

Union will not unscrew (see the Installation Instructions). If a shaft reverses rotation then a

flanged connection rather than a screw thread is strongly recommended.

At some time the seals in the Rotary Union will leak, so inspect regularly, also ensure that

leakages are not hazardous to personnel and that the Rotary Union is removed for repair

immediately. If leakages are not attended to promptly, bearing seizure may occur causing

flexible hose failure and massive leakage. Fit protective guards if leakages are likely to be

hazardous to personnel or equipment.

With oil systems minor leakages occur due to the natural characteristics of oil preventing

seal faces from contacting fully.
