Pup Joint Spacing Calculator

Enter the gap you need to fill. We size the smallest combination of API 5CT stock pup joints (2–12 ft), accounting for thread make-up loss.

Stock lengths: 2, 3, 4, 6, 8, 10, 12 ft (API 5CT Table C.27, standard tolerance ±3 in). Custom lengths to 20 ft on request. Always confirm spacing against your tally and saver-sub length.
