Hydraulics & Pneumatics

Clark Testing has been active in testing hydraulic-pneumatic components and systems for over 50 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.



Clark Testing is proud to continually maintain it's certification to ISO/IEC 17025:2005 accreditation, certificate number L2163.

Hydraulic-Pneumatic Testing

• 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, & diaphram): proof pressure, burst, impulse endurance, performance
• Hydraulic Cylinder/Acuators rod seals and wipers: endurance per SAE J1374
• Hoses, tubing and fittings: proof pressure, burst, impulse endurance
• Pumps and motors: performance, durability
