The **Hoke Hydraulic Pre-Set Tool** is a precision assembly and calibration tool designed to correctly preset and install Hoke high-pressure tube fittings and ferrule-based connection systems. The tool is used to ensure consistent, repeatable, and leak-tight tube connections by properly forming the ferrule set prior to final system assembly.

The pre-set tool is specifically intended for use with high-pressure hydraulic and instrumentation tubing systems where connection integrity is critical. It allows controlled compression of the front and back ferrules onto the tubing, ensuring optimal bite, alignment, and sealing performance without over-compression or tube damage. This improves system reliability and reduces the risk of leakage during installation and reassembly.

The tool is typically manufactured from hardened steel to withstand repeated high-load cycles and is matched to specific tube sizes and fitting series (commonly 1/4”, 3/8”, and 1/2” tubing sizes depending on configuration). It is used in combination with Hoke tube fittings in stainless steel hydraulic and process systems, where consistent make-up torque and sealing performance are required.

Typical applications include hydraulic test systems, high-pressure process skids, gas distribution systems, chemical injection systems, laboratory instrumentation, and any installation using Hoke compression fittings where repeatable, leak-free assembly is critical.
