TTNY
Our TTNY features a rugged straight to taper connection design. This is a double lead connection– for every revolution the connection makes up on two threads for faster make-up. The straight section is designed for deep stabbing, while the tapered section provides negative load flank threads, capable of providing sealing to 100% internal pressure while preventing jump-out. The primary metal-to-metal radial seal and the secondary axial metal seal, tested with combined loads of tension and compression to 95% Von Mises Ellipse (VME), providing 100% internal pressure with gas, at ambient and elevated temperature to 365°F.

FINITE ELEMENT ANALYSIS (FEA)
A finite element analysis (FEA) of the TTNY connection was conducted by an independent third party engineering firm to confirm the connection’s design performance.
TORQUE-TO-YIELD
Torque-to-yield testing was performed to verify the torsional limits of the all TTNY connections.
