Hydrostatic Pressure Systems and Test Tooling “UNPARALLELED PERFORMANCE AND SAFETY UNDER PRESSURE!” Hydrostatic Test Tools  Pressures up to 5,000 psi (345 bar)  0.13 in. to 6.63 in. OD (3.2 mm to 168.3 mm OD)  Collet grip and seal on tube OD  Lever operated model (sizes 1- 5)  Single air-operated model (sizes 1-5)  Dual air-operated model (sizes 6-8)  Pressure-compensated grip DESCRIPTION The TestMaster® Model LPH Series Hydrostatic Test Tools are specially designed to grip and provide positive sealing for plain end-tubing. The safety pre-grip of the clamping mechanism assures a constant, positive grip during any work or operation cycle. Tools are available with manual lever operation or pneumatic actuation. The tool can be used with a variety of services including air, water, oil, and other gases and liquids. The TestMaster® Model LPH Series Hydrostatic Test Tool is a snap-on tool suitable for hydrostatic pressure testing, air underwater testing, and cleaning 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. 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 lines, or residential and commercial heating and cooling systems. The Model LPH Series Tool handles standard and metric tube, pipe, and fitting sizes from 0.13 in. to 6.63 in. (3.2 mm to 168.3 mm) in diameter. Special tube sizes and tool configurations will be considered upon request. OPERATION Connect the Model LPH to the pressure line. Retract collets (by spring, handle squeeze, or air). Push tube end into tool until pressed against the tube stop. This instantly provides a complete seal. Engage collets (by spring, handle release, or air). Once collets are engaged, tool is ready for safe operation. Next, apply test pressure to desired level, but do not exceed maximum operating pressure. After pressure cycle is complete, retract collets as before and pull to remove from tube.
