Product Description
Product Description
Couplings are short lengths of pipe used to connect two joints of tubing or casing, which are painted with color codes on their external surface to indicate their grades. Couplings have internal threads (female thread form) machined to match the external threads (male thread form) of the long joints of casing & tubing. The two joints of casing & tubing are threaded into opposite ends of the casing & tubing coupling.
Size: 2 3/8" --- 20"Grade: H-40, J-55, K-55, C-75, L-80, N-80, C-95, AS-95, P-110, L80-13CR, etc.Thread: NU, EU, STC, LTC and BTCSucker Rod & Polished Rod CouplingsSucker rod coupling is used to connect two sucker rods.
Spray metal couplings are better in anti-corrosion than common sucker rod couplings.
Slim hole and full size couplings are available. Size: 5/8", 3/4", 7/8", 1" , 1-1/8" Grade: H19-T, 22-T, 25-T, etc.Product Parameters
