Product Description ------------------- The RIDGID 50557 Pressure Test Pump is a must have tool for pressure testing all types of piping systems for leaks. The hydraulic pressure test pump is designed to easily pressure test a wide range of fluid systems for leaks including heating, compressed air, oil, sprinkler and small bore pipeline systems using water, oil or a mixture of water and ethylene glycol. The pump requires very low effort to operate. It has a patented, variable two-stage lever-arm that reduces the handle force required and automatic pressure holding valves for easily pressurizing the system. Pressure is maintained automatically and there's no valve to be closed manually. Easily connect the pump to the system with the supplied hose and pump the handle to reach the desired pressure. The pressure is released by simply opening one valve when complete. Built for versatility, it's lightweight at only 14 pounds and has an easy locking handle for convenient transport. The 3.6-gallon reservoir capacity doubles as a handy tool box when not in use. Durable as well as versatile, the corrosion-resistant pressure test pump has a sturdy plastic container and an aluminum and carbon enhanced PTFE piston pump for longer life. The pressure gauge sits securely in the top cover, protecting it from damage. For reliability, there is a replaceable dirt filter on the inlet and outlet that keeps components clean. The pump in this cooling system pressure test kit has a 725 PSI (50 Bar) maximum pressure and a 38 cm3 volume/stroke. RIDGID covers its products with a lifetime warranty against defects in material or workmanship for the life of the tool. Since 1923, RIDGID has remained the symbol of certainty to dedicated professionals of the expert trades. Every tool that bears the RIDGID brand is engineered to the same high standards of quality, strength and endurance, as was that first heavy-duty pipe wrench more than 80 years ago. From the Manufacturer --------------------- The Rigid 50557 1450 Pressure Test Pump tests hydraulically for leaks in installations which are required to be leak proof. The Rigid 50557 1450 Pressure Test Pump will test systems up to 725 PSI. The Rigid 50557 1450 Pressure Test Pump is especially for use in heating, compressed air, refrigeration systems, oil installations, sprinkler systems and other small bore pipe installations.
