Hydrostatic Pressure Systems and Test Tooling Medium Pressure Gas Test Tools  Pressures up to 20,000 psi (1,379 bar) Side View  0.13 in. to 3.00 in. OD (3.2 mm to 76.2 mm OD)  Collet grip and seal on tube OD  Manual lever grip release Port View Front View The patented TestMaster® Model MPG Series Medium Pressure Gas Test Tool is specially designed to grip and provide positive sealing for plain end-tubing. The safety pre-grip of the clamping mechanisms assures a constant, positive grip during any work or operation cycle. The tool can be used with a variety of gases including helium, nitrogen, and hydrogen. The TestMaster® Model MPG Series Medium Pressure Gas Tool is a snap-on tool using gas for pressure testing, air underwater testing, and cleaning applications with working pressures up to 20,000 psi (1,379 bar). Additionally, they can be used for production testing of tubes, tube assemblies, and systems. This tool conforms to military, nuclear, automotive, and aerospace testing specifications such as API, ASTM, ASME, ISO, DIN, and BS. This precision-machined tool provides versatility for use in pressure testing applications. The compact, balanced design is particularly suited to restricted areas, such as aircraft hydraulic and fuel line locations, or residential and commercial heating and cooling systems. The Model MPG Series Tool handles standard and metric tube, pipe, and fitting sizes from 0.13 in. to 3.00 in. (3.2 mm to 76.2 mm) in diameter. Special tube sizes and tool configurations will be considered upon request. OPERATION Connect the Model MPG 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.
