Hydrostatic Pressure Systems and Test Tooling “UNPARALLELED PERFORMANCE AND SAFETY UNDER PRESSURE!” Hydrostatic Test Tools  Pressures up to 5,000 psi (345 bar)  0.31 in. to 3.00 in. ID (7.9 mm to 76.2 mm ID)  Collet grip and seal on tube ID  Air-actuated collet pre-grip and release  Pressure-compensated design The patented TestMaster® Model 300 Series Hydrostatic Test Tool offers inside gripping and sealing specially designed for high-pressure hydrostatic and leak testing of tubes swaged into sheets. The hydraulic sealing mechanism along with the safety spring pre-grip, assures a constant, positive grip during any work or operation cycle. The tool can be used with a variety of services including air, water, oil, or other liquids on request. The TestMaster® Model 300 Series Hydrostatic Test Tool is a used in a variety of HVAC production applications including, boiler tube assemblies, shell and tube heat exchangers, boxtype heat exchangers, and other tube assemblies. The Model 300 tool is suitable for applications with working pressures up to 5,000 psi (345 bar). This tool conforms to military, nuclear, automotive, and aerospace testing specifications such as API, ASTM, ASME, ISO, DIN, and BS. The Model 300 Series Tool is suitable for hydrostatic pressure testing up to 5,000 psi (345 bar). The compact, balanced design is particularly suited to restricted work areas with limited space. The Model 300 Series Tool handles standard and metric tube, pipe, and fitting sizes from 0.31 in. to 3.00 in. (7.9 mm to 76.2 mm) in diameter. Special tube sizes and tool configurations will be considered upon request. OPERATION Connect the Model 300 Tool to the test system by attaching one air line to the release port, the other air line to the clamp port, and the hydraulic line to the pressure port. Using suitable valving for manual or automatic testing, apply air pressure of 50 to 90 psi (3.4 to 6.2 bar) to the release port which retracts the collet. Insert tool into tube until pressed against tube stop. Apply air to clamp side. Tool now has positive seal and a grip on the tube. Next apply pressure flow to run test, but do not exceed maximum working pressure. After test is completed the pressure will drop to 0, then apply air pressure to release port and remove the tool from the tube. MATERIALS Wetted Parts: Heat-treated, stainless steel TOOL CONFIGURATION Collet Grip and Seal: On tube OD Gripping: Pressure-compensated Air-Operated: Air-pilot clamp and release Air Requirements: 50 to 90 psi (3.4 to 6.2 bar) OPERATING CONDITIONS Maximum Pressure: 5,000 psi (345 bar) Temperature: 32º F to 120º F (0º C to 49º C) Services: Air, water, oil, or other liquids on request Tube ID Range: 0.31 in. to 3.00 in.
