High-collapse wireline seals resist external pressure in deep wells. The seal body is reinforced with steel rings to prevent implosion. These seals are rated for 25,000 psi external pressure in ultra-deepwater. They enable wireline operations below mudline in high-pressure formations. They support reservoir evaluation in frontier exploration wells where conventional testing methods ar... https://globalsealstech.com/product-category/oil-gas-seals/oil-free-lubricated-pump-seals/
