"UNPARALLELED PERFORMANCE AND SAFETY UNDER PRESSURE!"® TestMaster® Model 264 Series Hydrostatic Test Tools ■ Pressures up to 20,000 psi (1,379 bar) ■ 0.13 in. to 1.78 in. OD (3.2 mm to 45.2 mm OD) ■ Collet grip and seal on tube OD ■ Manual lever grip release ■ Pressure-compensated spring grip Maximum Pressure: Temperature: Services: Tube OD Range: OD Tolerance: DESCRIPTION The patented TestMaster® Model 264 Series Hydrostatic Test Tool offers fast, snap-on coupling and positive sealing of tubes and tube assemblies in systems. The hydraulic sealing mechanisms along with the safety spring pre-grip, assure a constant, positive grip during any work or operation cycle. The tool can be used with a variety of services including water, oil, or other liquids on request. This precision-machined tooling provides versatility for use in high-pressure testing applications. Its short, outside collet grip is beneficial for applications with short tube ends. The compact, balanced design of the Model 264 connects and disconnects easily; and is particularly suited for space restricted work areas, such as aircraft hydraulic and fuel lines. The Model 264 Series Tool comes in standard and metric tube, pipe, and fitting sizes from 0.13 in. to 1.78 in. (3.2 mm to 45.2 mm) in diameter. Special tube sizes and tool configurations will be considered upon request. OPERATION Connect the Model 264 Tool to the pressure line. Attach the tool to the tube by pressing the handle to retract collets. Push the tube into the tool until pressed against the tube stop. This instantly provides a complete seal. When the tool's handle is released the collets are engaged and ready for safe operation. Next apply test pressure to desired level, but do not exceed maximum operating pressure. To disconnect after operation cycles, press handle to release collets and pull to remove tool. APPLICATION The TestMaster® Model 264 Series Hydrostatic Test Tool is a snap-on tool, suitable for hydrostatic pressure testing and hydro-expansion of tubes with working pressures up to 20,000 psi (1,379 bar). This tool conforms to military, nuclear, automotive, and aerospace testing specifications such as API, ASTM, ASME, ISO, DIN, and BS.
