3-1/2" 8 ft Pup Joint – API 5CT Seamless Tubing with EUE Thread

The 3-1/2" 8 ft Pup Joint is a short-length tubing component engineered to provide precise adjustments to production string lengths in oil and gas wells. It is commonly used to space out completion equipment, tie in surface hardware, or align packers, safety valves, and other downhole tools.

Manufactured from seamless tubing according to API 5CT standards, this pup joint offers the same pressure and mechanical strength as full-length joints. Threaded with External Upset Ends (EUE), it is compatible with standard API tubing strings and supplied with a coupling. Available in standard grades like J55, N80, L80, and P110, it is suitable for a wide range of well conditions—from conventional onshore wells to HPHT and corrosive environments.
