The backup ring can prevent the O-ring from being squeezed to the low pressure side under pressure
The main function of the retaining ring is to prevent the O-ring from being squeezed onto the low-pressure side under the action of pressure when the O-ring gap is large,in which the O-ring may be damaged and consequently lose its function if there is excessive pressure.
