Kerr Pumps improves its market shifting Frac 1 CONNECT fluid end design with threaded cover plates and hammer nuts to significantly reduce routine valve and seat maintenance times.

The F1X provides the familiar threaded cover cap of the legacy style fluid end with an added fail-safe protection. The major problem this design solves is seized cover caps from broken threads.

The Frac One X was developed to bridge the gap until a longer lasting, 200+ hour valve is introduced.
