Reservoir Tank Cap Non- Vented

The Reservoir Tank Cap Non-Vented from KRC Power Steering is a precision-engineered replacement cap designed for high-pressure power steering systems that require sealed, non-vented operation. This twist-on cap prevents fluid oxidation and contamination by maintaining a closed pressurized environment within the reservoir, making it essential for vehicles running performance power steering setups or custom hydraulic systems. Users managing modified steering systems, race vehicles, or systems with auxiliary coolers will find this cap critical for maintaining system integrity and fluid longevity.

Constructed from steel with a zinc oxide finish, the Reservoir Tank Cap Non-Vented delivers durability and corrosion resistance in demanding under-hood environments. The twist-on design eliminates the need for special tools while ensuring a secure, repeatable seal that withstands system pressure without leakage or fluid weeping. Unlike vented caps that allow atmospheric exchange, this non-vented configuration maintains positive pressure within the reservoir, reducing aeration and foam formation—critical factors in performance applications where fluid degradation accelerates failure rates. The compact design integrates seamlessly with KRC Power Steering reservoir assemblies.

Technicians and performance builders installing KRC Power Steering reservoirs will recognize this cap as OEM-specification hardware engineered for closed-circuit systems, particularly those incorporating remote reservoirs, high-flow pumps, or cooler circuits where venting is not permitted. Installation is straightforward—simply twist onto the matching reservoir neck until hand-tight for a vapor-sealed fit. Ensure system pressure relief is properly set to prevent cap damage; typical automotive power steering systems operate 1,200–1,500 PSI. This cap is sold as a single unit and pairs with KRC reservoirs across steering modernization projects.
