At Maximator Test, LLC., we provide a range of leak testing options with different fluid media, including hydrostatic leak testing at pressures as high as 145,000 psi and 65,000 psi using hydraulic fluid or water, respectively. We can also conduct leak testing pneumatically utilizing Nitrogen, Helium, or a Nitrogen/Hydrogen mixture (95%-N2,5%-H2).
Our team has the option of using a computer-regulated, plc-controlled test bench or an NIST traceable pressure gauge-equipped, manually operated gas booster assembly. The test bench is equipped with primary and secondary transducers calibrated to ISO/IEC 17025 standards, and offers 10 programmable pressure intervals. The test is witnessed using various protective safety features, and the data can be provided in both CSV and PDF formats.

Hydrostatic Leak Testing Using Water
Maximator Test can fulfill your needs for high-pressure hydrostatic leak testing at pressures up to 65,000psi using water (distilled or deionized) as a medium. Using water based hydrostatic leak testing processes, our team fills internal cavities at high pressures and monitors the outside of the component for leakage, or pressure drops on our gages or pressure vs. time graphs. We can identify and trace leakage in real time to uncover potential design flaws in the test assembly. Should we discover a leak, this data can be used to correct the leak’s root cause, preventing the problem from reoccuring during future production.
Below is a leak found on a flanged assembly. This component was pressurized to a safety factor of 4 using water as a medium and then visually inspected for evidence of leakage. Trust Maximator Test to accurately locate weak links in your system to help you provide your customers with unrivaled safety.
Hydrostatic Leak Testing Using Hydraulic Fluid
Leak Testing using hydraulic fluid is identical to using water with some additional application specific benefits. For requirements exceeding 65,000 psi, a hydraulic fluid will be used to reach pressures up to 145,000 psi. Reaching these extreme pressures is critical in Leak Testing modern high strength alloys such as precipitation hardened stainless, maraging steels, and more. There is a corrosion resistant benefit of using hydraulic fluid as well, where an unfinished product may begin to rust or corrode when introduced to water. With our high ratio intensifier, 145,000 psi can be reached quickly within a 15 second period depending on the overall volume of the component.
See below for a typical leak formed when using hydraulic fluid. With pressures up to 145,000psi, Maximator Test can confidently Leak Test the toughest components in the market today.
At Maximator Test, we conduct hydrostatic Leak Testing with the goal of improving high-pressure component designs, identifying the minimum and maximum burst pressures, proving seal or component designs, and locating the source of a failure. Leak testing can show a fundamental fault in the system, and high leak rates in specific areas could point to an improperly aligned gasket or valve connections that are misaligned or improperly threaded. Additionally, hydrostatic burst testing is effective for identifying high-pressure part failure.
