Pneumatic grips operate using compressed air, while hydraulic grips operate using hydraulic pressure, so the required utilities depend on the grip type and the way you want to generate and control clamping force on your UTM.

For pneumatic grips, plan for a stable source of clean, dry compressed air delivered to the grip’s valve or control hardware. Most labs also include basic air conditioning and control components to keep clamping consistent from operator to operator and shift to shift:

• Compressed air drop at the tester, with appropriate hose and fittings
• Regulator (and typically filtration) to set and maintain clamp pressure
• A simple actuation method such as a hand valve or foot control, depending on your workflow

For hydraulic grips, you will need a hydraulic pressure supply. This can be provided by a servo-hydraulic test frame’s existing hydraulics or by a dedicated hydraulic power unit, which typically also requires electrical power, hydraulic hoses, and safe line routing around the test area.
