API 3/4" FS Class T sucker rod coupling
The API 3/4" FS Class T sucker rod coupling is a precision-engineered component for oil and gas pumping systems, designed to connect sucker rods with a leak-free seal under high-pressure conditions. This coupling adheres to API specifications, ensuring compatibility with standard sucker rod assemblies in extraction operations. The full-size (FS) design accommodates 3/4" rods, while the Class T designation indicates a heavy-duty build for demanding environments.
Constructed from high-strength steel, the coupling resists wear and fatigue in abrasive downhole conditions. Industry-standard FS couplings typically use AISI 4140 or 4340 alloy steel, heat-treated to achieve hardness levels between HRC 22-30 for optimal toughness. The internal threads are machined to API 11B specifications, with a typical thread pitch of 8 threads per inch for 3/4" couplings, ensuring a secure, vibration-resistant connection.
This coupling is primarily used in beam pumping units for onshore oil wells, where it transmits the reciprocating motion from the surface to the downhole pump. Buyers include oilfield service companies, drilling contractors, and equipment manufacturers sourcing reliable connections for artificial lift systems. Trade terms such as MOQ, Incoterms, and packaging should be confirmed directly with Yantai Pertoleum Machine Fittings Co., Ltd., as these are not specified in the listing.

Sourcing API 3/4" FS Class T sucker rod coupling from Yantai Pertoleum Machine Fittings Co., Ltd. - China Import Guide
Before ordering, verify that the coupling meets API 11B specifications and is compatible with your sucker rod assembly. Request material test reports (MTRs) to confirm the steel grade and hardness, as these directly impact performance in downhole conditions. Check that the supplier can provide third-party inspection certificates if required by your quality management system.
Confirm the logistics details, including lead time, which is not specified in the listing. Clarify the Incoterms offered by Yantai Pertoleum Machine Fittings Co., Ltd., as this will determine your responsibilities for shipping, insurance, and customs clearance. Packaging should be suitable for international transport, and buyers should ensure it complies with their country’s import regulations for steel products.
Inspect the couplings upon receipt for thread damage, corrosion, or dimensional deviations. Use a thread gauge to verify the pitch and a caliper to check the overall length and diameter against API 11B tolerances. Request a hydrostatic test report if the couplings will be used in high-pressure applications, and ensure all documentation, including certificates of conformity, is provided before payment.
