• Blak-JAK Torque Pro Lite

    Valve cover retention system designed to improve fluid end maintenance procedures while reducing risk exposure.

    The Blak-JAK Torque pro Lite utilizes a hydraulic wrench to tighten and loosen the valve cap retainer and improves safety by eliminating the need for hammers.

    As with other Blak-JAK systems, the Blak-JAK Torque Pro Lite uses hydraulic over mechanical retention, and no hydraulics stay on the pump while the pump is in operation. This system works with OEM valve covers as well as Mission "L" style plugs. No modification to the fluid end is required.
