TKC Convertible EUE
The TKC Convertible EUE connection system is a means of "extending the performance" of API 8rd threaded tubing.
The heart of the system is a special close-tolerance coupling and "patented" press fit convertible metal ring that occupies what would be the open "J" area of an API connection. In conjunction with special TKC Convertible pin end finish, the design permits the pin ends to shoulder in the coupling, providing for a high torque, power-tight make-up.
The TKC Convertible EUE system enhances the 8rd connection's structural strength and provides an axial metal-to-metal seal to complement the 8rd thread seal.
Moreover, the TKC Convertible EUE connection system results in an internally flush, recess-free bore for improved bending, compression and torsion resistance.
