The API external-upset-end (EUE) tubing connection is widely used because it is good, serviceable connection in most wells. The EUE joint has a designed joint strength in tension and pressure strenght greater than that of the pipe body and, therefore, is considered a 100% joint efficient connection.

To improve the seal perforemance of API EUE tubing in high-pressure service, a grooved coupling ,which accepts nonmetiallic seal rings, is sometimes used in teh coupling (see API SPEC 5CTSR13)
