Hydro-Expansion ExpanTek® Model 35 Series Tools - Up to 15,000 PSI (1,034 Bar)

The patented precision machined tool provides versatility for use in hydro - expansion applications. Model 35 Hydro-Expansion Tool is designed for high pressure expansion of tubing or pipe. This unique tool, along with a high pressure unit, will rapidly expand tubing for refrigeration coils, boilers, tubular assemblies and many other associated products. Its short, outside collet grip is very helpful for applications with short tube ends. The deep tube swallow allows for long un-expanded tube length.

The Model 35 tool will handle standard and metric tube and fitting sizes from 0.250” to 1.000” (6.3 mm to 25.40 mm) in diameter. Special sizes and configurations will be considered upon request.

The Model 35 is a snap-on coupling suitable for hydro-expansion on tube with standard OD tolerances needing expansion pressures up to 15,000 PSI (1,034 Bar).

For hydro-expansion attach the Model 35 tool with optional NuQuip® Automatic Air Bleed to one end of the tube. Adapt the second Model 35 tool to a pressure service line and slip it over the remaining end. Press both tools firmly against the internal stop. When the service line is pressurized to 50 PSI (3.45 Bar), the collets are activated for a positive grip. Continue to pressurize the tube until expansion pressure is reached. Use caution not to exceed maximum pressure rating of the tool. After the tube is expanded and the service line pressure drops to 0 PSI, the collets automatically release, allowing quick removal of the tools from the work piece.
