3093 – Vented Hydraulic Oil Tank Cap

The 3093 Vented Hydraulic Oil Tank Cap is a service-grade reservoir cap designed to seal the hydraulic tank while allowing proper ventilation. The integrated vent/breather helps equalize pressure during system operation and temperature changes, reducing the risk of leaks, cavitation, or tank deformation.

Commonly used on Larson Cable Trailers hydraulic systems, this cap is ideal for replacement during maintenance or when upgrading worn or damaged reservoir components.
