For Force Graphs, see the EOAT Learn More Page.
*The gripping force is the arithmetic sum of the individual finger forces at “F” mm distance at 6 bar.
**Transportable weight calculated with friction coefficient between part and fingers of μ = 0.1 and safety factor fs = 2. Form-fitting fingers may allow larger part weight.
***Closing and opening times are purely the times that the base jaws are in motion. Valve switching, hose filling, PLC/CNC reactions, and other potential delays are not included and must be taken into consideration when determining cycle times.
The shown force and moments are applied per base jaw and may occur simultaneously. My may apply separately to the moment generated by the gripping force itself.

Vektek’s VSO sealed pneumatic gripper carries an IP67 rating, which certifies dust-tight construction and temporary water immersion tolerance. Engineers get a waterproof gripper that performs through aggressive wash cycles and humid production conditions.
Built for Harsh Environments
The VSO IP67 gripper combines a hard-anodized aluminum housing with precision-ground steel internals to deliver structural durability in corrosive and high-moisture settings. The IP67 seal helps protect the wedge-hook mechanism from dust ingress and water exposure, supporting jaw movement through frequent washdown cycles. The double-acting design supports both internal and external gripping across several size variants, at pressures from 2.5 to 8 bar.
Closing grip force runs from 110 N on the VSO 40 to 3,040 N on the VSO 160 at 6 bar, which suits food product handling, pharmaceutical packaging and light industrial transfer tasks. Proximity switch mounting locations deliver jaw position feedback for automated cell sequencing. Match the gripper to the robot flange with our universal pneumatic EOAT interface.
Where a Sealed Pneumatic Gripper Excels
Gripper selection in demanding environments depends on contamination type, wash cycle frequency and the hygiene standard the application demands. The VSO IP67 gripper addresses these high-demand sectors:
- Food processing and packaging: Our washdown gripper tolerates high-pressure cleaning cycles between production runs. The IP67 seal helps keep moisture and cleaning solutions away from internal components.
- Pharmaceutical and medical device manufacturing: Controlled settings demand grippers that resist contamination and tolerate repeated sanitization. The VSO’s sealed construction supports regular sanitization procedures in these environments.
- Chemical handling: The corrosion-resistant gripper withstands exposure to process chemicals in transfer applications that demand sealed, durable construction.
FAQs
Protection level selection impacts maintenance intervals, component reliability and regulatory compliance. These answers help engineers confirm the VSO is the right fit for their application.
What does IP67 rating mean?
The IP67 rating certifies that the unit is dust-tight and withstands temporary water immersion to a depth of 1 meter for 30 minutes. Engineers who want a waterproof or food-grade gripper will find that this protection level suits washdown areas and facilities where cleaning agents contact the unit directly.
Do I need IP67, or will a standard gripper work?
Select the VSO series when the application involves regular washdown, direct moisture exposure, food-grade hygiene requirements or corrosive chemical contact. For dry, controlled manufacturing settings, the VGP 2-Finger Gripper may be a suitable option.
Are special pneumatic connections required to maintain the IP67 rating?
The IP67 rating covers the VSO gripper body and internal mechanism. Air supply fittings and manifold connections require appropriate sealing to maintain protection at the connection points. Our engineering team can confirm the right connection approach for your specific washdown or high-humidity setup.
Specify the Right Sealed Gripper for Your Environment
VSO grippers integrate with Vektek’s broader workholding lineup. Our U.S.-based technical specialists evaluate your environment type, wash cycle frequency and contamination exposure to help determine whether IP67 sealing fits your application or a different end of arm tooling unit meets the requirement.
