The API external-upset-end (EUE) tubing connection provides excellent service performance in most well applications. EUE joints are designed with superior joint strength in tension and pressure resistance, exceeding pipe body specifications for 100% joint efficiency.

For enhanced sealing in high-pressure applications, grooved couplings can accommodate nonmetallic seal rings as specified in API SPEC 5CTSR13. All couplings are manufactured from high-quality seamless steel in strict compliance with API 5CT/5B standards.
