Wireline seal test units verify performance before field deployment. The unit simulates well pressure and cable movement. Seal leakage is measured with helium mass spectrometry. These seals are qualified to 0.01 cc/min leak rate at 15,000 psi. They ensure reliability in critical barrier applications where failure could lead to loss of well control and environmental incidents in sensit... https://globalsealstech.com/product-category/oil-gas-seals/oil-free-lubricated-pump-seals/
