Hydrostatic Pressure Systems and Test Tooling TestMaster® Model 310 Series Hydrostatic Hose Test Tools ■ Pressures up to 30,000 psi (2,068 bar) ■ to %" NPT threads ■ Collet grip on threaded OD ■ Manually operated preload ■ Seals on face of fitting opening ■ Custom sizes available Collet Grip: Gripping: Seal: Sealing: Maximum Pressure: Temperature: Services: Nominal Thread Size: OD Tolerance: DESCRIPTION The patented TestMaster® Model 310 Series Hydrostatic Hose Test Tool offers fast snap-on coupling and positive sealing of high-pressure threaded hoses and fittings. The proprietary collet design with its small inside grip, helps with short end applications. Minimal marking collets preserve the integrity of the test piece without deforming threads. The tool can be used with a variety of services including water, oil, and other liquids. This precision-machined tool is versatile for use in high-pressure testing applications. In restricted areas, the balanced and compact design of the Model 310 connects and disconnects easily. The Model 310 Tool handles standard %" to %" NPT threads. Special sizes and tool configurations will be considered upon request. OPERATION Connect the Model 310 Tool to a pressure source and compress handle to retract O-ring seal. With handle compressed, insert threaded portion of correct size fitting into tool collet. Release the handle and verify that threads are properly seated in the collet. Next apply test pressure to desired level, but do not exceed maximum operating pressure. When the test is complete and pressure reduced to 0 psi in the service line, compress the tool handle and pull tested fitting from the collet. APPLICATION The TestMaster® Model 310 Series Hydrostatic Test Tool is a snap-on tool, suitable for hydrostatic pressure testing of hoses and fittings with NPT or standard thread configurations with working pressures up to 30,000 psi (2,068 bar). This tool conforms to military, nuclear, automotive, and aerospace testing specifications such as API, ASTM, ASME, ISO, DIN, and BS.
