Silea couplers can be used in the petrochemical industry when dry coupling is required. Manufactured according to the API RP 1004 standard regulations, are supplied with a 4” TTMA flange and are made of aluminium alloy. The surfaces subject to wear are hard coated. The standard fluoroelastomer (Viton®) seals are easily removable to allow maintenance operations. This type of coupling prevents spillage during the connection/disconnection operations and ensures safety conditions for the operators.
Female API RP 1004 Dry Break Coupler, Model 513
The female dry break coupler SILEA 513 is full interlocked. It cannot be opened unless it is properly connected, and cannot be disconnected when the poppet is open. It contains two safety trigger and four interlock lugs for secure connection.

Male API RP 1004 Dry Break Couplers
(adaptors), Model 511 and 512
These two adaptors are utilized for the loading and unloading operation of movable tankers. They are installed on the tank-trucks or tank wagons. In addition to allowing an easy coupling to the loading and unloading arms, they assure a coupling without any spillage and the complete safety during the transferring process.
The adaptor 512 is equipped with a operating handle permitting the manual opening and closing of the valve, and a sight glass.
The adaptors are manufactured in an aluminium alloy. The surfaces subject to wear are hard coated. The standard seals are in fluoroelastomer (Viton®). The items are 4” TTMA flanged.
While loading the tank-vehicle has to be connected to the vapor recovery unit to maintain the operating pressure within the 0,5 bar
