Tri State Hydraulics



Hydraulics & Pneumatics

Clark Testing has been active in testing hydraulic-pneumatic components and systems for over 20 years. Products tested range from automotive fuel filters to 15 inch diameter hydraulic actuators. A large selection of equipment, instrumentation and test benches are available to support your testing program. Component performance can be evaluated over a temperature range of -346° F to +600° F. 

Hydraulic & Pneumatic Laboratory Capabilities 

Clark Testing hydraulics and pneumatics testing is primarily suited for applications in aerospace, automotive, heavy equipment, military, nuclear, power generation, and rail and transportation. However, we are constantly expanding our services, so contact us with your needs for customized hydraulic and pneumatic test programs.


Hydraulic-Pneumatic Testing

For hydraulic component testing, we offer a wide array of qualification services. We can also combine a series of tests to create a hydraulic-pneumatic system testing program, ensuring cost-effective solutions that fulfill your industry's testing requirements.

  • Actuators: proof pressure, burst, piston drag, cyclic (stroke) endurance, impulse endurance

  • Valves: performance and durability

  • Oil Coolers / Heat Exchangers: pressure drop, pressure, burst and/or shock

  • Accumulators (piston, bladder, & diaphragm): proof pressure, burst, impulse endurance, performance

  • Hydraulic Cylinder/Actuators rod seals and wipers: endurance per SAE J1374

  • Hoses, tubing and fittings: proof pressure, burst, impulse endurance

  • Pumps and motors: performance and durability

  • System simulation: field duty cycles, accelerated testing, failure analysis

  • System evaluation: on-vehicle performance, prototype testing, efficiency studies, lubrication studies

Above testing can be combined with thermal cycling and aging. 

Hydraulic-Pneumatic Laboratory Test Thresholds
