Hydraulic spin-on filters with increased wall thickness and more stable end plates are specially matched to the high pressures in hydraulic systems of up to 40 bar. Often the multifaceted collar is eliminated to allow greater pulsation dampening. More durable materials such as special non-wovens and synthetic media are used in hydraulic spin-on filters and filter cartridges, since hydraulic oil contains different components.

Special spin-on filters and filter cartridges that are suitable for use with hydraulic oil are available.
