Product Details

The API metal coupling is an internally threaded cylinder for connecting two threaded pipes. It is an integral part of the tubing and casing. Each tubing or casing should be equipped with an API coupling. The casing with different thread types selects different types of this fitting. Therefore, the product is mainly divided into buttress thread and round thread types, which correspond to buttress and round thread casing respectively.
