API standard

Since the 1970's the petroleum distribution industry is changing from top to bottom loading operation. Key factor in the revamping process is the API RP 1004. This standard determines the connection parameters of the coupler. It is accepted by all leading coupler manufacturers and petroleum distributing companies world wide.

Emco Wheaton has recently enhanced its family of API couplings. Each coupler incorporates a host of patented features. This will provide trouble free operation and ensure a clean and spill free loading rack. The Emco Wheaton API couplers are approved and recommended by the world’s major oil companies. They operate successfully in the most demanding environments.

J0451 API coupler

The J0451 is used in the petroleum industry for more than 25 years. It is the most economical slide on /pull off API coupler for a safe and leak-free operation. As a standard the recently re-engineered J0451 can be applied for a pressure of 10 bar. The coupler now features 5 claws for better load distribution when connected to the tank truck adaptor. It has a more ergonomic sleeve an lever system to provide an even easier and more comfortable operation.

J0452 API coupler

The J0452 series of API couplers is the most advanced range of couplers available in the global market today. With a number of improved components, the J0452 replaces the popular K2/K2P as the snap-on / snap-off coupler of choice. One of these components is the unique pump system (J0452-051P) that ensures a clean and spill-free loading process.

Perolo Camsec API coupler

The Perolo Camsec coupling is an API coupler with the unique feature of a built-in calibrated check valve. When a check valve is required, this design gives a considerable saving on weight and overall dimensions. There is also the option for a proximity switch to detect if the API coupler is -correctly- connected.
