Selection Depends on the Operating Conditions

Dimensions alone are not enough. We confirm the seal material and profile against the actual working parameters of the assembly.

Operating temperatureDepends on the seal material and is specified for each part number.
Hydraulic fluidMineral, synthetic and biodegradable fluids require different seal materials.
Pressure and speedDetermine the seal profile and whether anti-extrusion elements are needed.
Assembly designHousing dimensions, grooves, guide rings and wiper seals.

For low-temperature operation, special seal compounds are selected only where confirmed technical data for the specific part number is available.

Mention of equipment brands indicates compatibility-based selection only. VOLGA is not an authorised dealer or representative of these manufacturers.
