Hammerless Frac Suction Cover Retainer

The Hammerless Frac Suction Cover Retainer allows for the installation and loading of joints without the use of sledge hammers, reducing the risk of injury to onsite personnel. It improves safety on the jobsite by holding a pump’s valve cover in place during pumping operations, and prolongs fluid end life by eliminating valve cover seal issues, fluid end thread failures and stuck retainer nuts.
