Leakage test


To quantify Teadit Origin™ RC510 leakage rate when subjected to 35 psi of pressure and 250ft-lbs of torque, in comparison to other designs used in the industry.

Test Parameters

Pressurize the rig at 35 psi, and at room temperature.
Leak measurements performed after a cycle is completed.

One cycle: 24 hour test, open/close lid each hour for eight hours, close lid and pressurize for next 16 hours.


Teadit Origin™ RC510 presents the best results in leakage rate, averaging 0.003mg/s/m. It outperformed all competitors in tests performed in Teadit’s facility, in Texas/USA, as shown in the adjacent graphs.
