API NUE Tubing Couplings

 

We carry size range of 2-3/8", 2-7/8″, 3-1/2″,4″ and 4-1/2″ in J55, K55, N80, P110 grade. All of our couplings meet the API Specifications 5CT/5B.

 

API nonupset (NUE) tubing is used much less than EUE tubing. The cost of NUE is only slightly less than EUE, and the joint strength is substantially less. The coupling joint diameter of NUE is less than EUE, which offers some advantages when clearance is small. API NUE joints are available in sizes of 1.050 to 4.500 in.
