We offer a wide range of tubing couplings in various sizes, including 2-3/8", 2-7/8", 3-1/2", 4", and 4-1/2". These couplings are available in grades J55, K55, N80, and P110, meeting the API 5CT/5B specifications.
Tubing couplings are short pipe sections used for connecting two pieces of tubing or casing. We provide two types of couplings: External Upset End (EUE) and Non-Upset End (NUE). Our advanced CNC machines and imported cutting tools ensure precise threading to guarantee compatibility and interchangeability between different coupling sizes.
To maintain the highest quality standards, we conduct comprehensive testing using specialized tools. This includes measuring tape accuracy, checking pitch alignment, analyzing tooth depth consistency, and verifying profile integrity.
Our inventory includes a wide selection of couplings ranging from 2-3/8" to 20'' in different grades such as J55,K55,N80,and P110. All our products adhere to strict API 5CT specifications to ensure excellent performance and reliability within the industry.
Here are some key details:

API Specifications - API 5CT /5B
Coupling types:
EUE & NUE
Grade options:
J55/K55/N80/L80/P110
Packaging:
Couplings are securely packaged on wooden pallets with tight wrapping/W paper cartons.
During production, we carefully select raw materials that undergo rigorous mechanical tests such as tensile strength evaluations and impact tests. Chemical properties control is also conducted. For specific material grades like C90 or T95, sulfide stress cracking tests are carried out. We ensure precise size tolerances, including outer diameter (OD), wall thickness, length, and straightness. Thread quality is closely monitored, considering threads per inch and thread angle parameters (premium threaded options undergo even more stringent checks).
Additionally, we apply heat treatment to enhance the couplings' mechanical properties. Extra markings required by specifications are added, and material certification verification is conducted. Our products comply with specific Product Specification Levels (PSL-2 or PSL-3) as per industry standards.
