Reducing coupling is used to fire water supply line interface to connect two different caliber, which is made up of body, seal seat, vice body and other components, the, vice body with threaded connection, both ends have a pair of latches for easy connection.
Reducing coupling is used in the hose, gun, fire hydrant between different caliber series; market mostly turn into 65mm-50mm; 80mm-65mm two kinds of turn.
When used, the interface of the two carbonyl reducing other interfaces with the same caliber, clockwise 90 ° to together into a
Body rotated 90 ° counterclockwise direction can be freed, usually within the interface should always check whether there washers, connect the interface to check the inner gasket is intact, attention to sealing, the interface should prevent collisions affect the normal connection, usually not with acid and other chemicals mixed up, away from heat, to prevent rubber aging.
