Industrial Sourcing &
Engineering Quality

OFS offers sourcing and procurement solutions for high-quality oilfield casing couplings designed to connect individual lengths of casing pipes in oil and gas wells. Casing couplings are essential components of the casing string, providing secure threaded connections and supporting structural integrity throughout drilling, completion and production operations. Our sourcing capabilities cover API Specification 5CT casing couplings in various sizes, steel grades and thread configurations, including STC (Short Thread Coupling), LTC (Long Thread Coupling) and BTC (Buttress Thread Coupling). Available material grades include H40, J55, K55, N80, L80, C95 and P110, with corrosion-resistant options such as L80-13Cr available for specified operating environments. Casing couplings are used in onshore and offshore drilling operations, surface casing, intermediate casing and production casing applications. OFS coordinates manufacturer sourcing, technical specification reviews, dimensional requirements, thread configuration verification, quality documentation and international logistics. Our procurement approach focuses on matching coupling dimensions, material grades, connection types and applicable industry standards with specific project requirements. Contact our team with your required casing size, steel grade, thread type and quantity to receive a project-specific quotation.
