VO-4 Series Explosion-Proof Cable Gland
The VO-4 series explosion-proof cable gland uses a mechanical cable-clamping construction. The supplied catalogue lists nine models for cable outside diameters from 5–12 mm to 50–90 mm.
- G pipe thread and metric thread references appear together in the source table; confirm the required order thread.
- Brass or stainless steel is listed as the material choice.
- Catalogue marking: Exd IIC Gb; catalogue protection level: IP66.
- Model-by-model C lengths are provided for dimensional comparison.
Overview
The VO-4 series explosion-proof cable gland uses a mechanical cable-clamping device. The supplied catalogue lists brass or stainless-steel construction, nine model codes and corresponding cable diameter ranges. The Ex marking and IP rating below reflect the catalogue; project approval documents should be checked separately.
Features
- Mechanical cable-clamping construction described in the source.
- Nine model codes with cable outside diameter ranges and C dimensions.
- Catalogue provides G pipe thread and metric thread references. Metric or NPT thread specifications can be produced according to the source; a particular order thread should be stated in the enquiry.

Selection Guide
Specify the model, actual cable outside diameter, required thread type and material when enquiring. The catalogue says metric or NPT pipe threads may be produced, but does not assign separate order codes or dimensions to those options. Check the relevant approval documentation for the installation before specifying a hazardous-area product.
