Reservoir Tank Cap Non- Vented

The Reservoir Tank Cap Non-Vented from KRC Power Steering is an essential component for hydraulic power steering systems, especially in high-performance and custom automotive builds where pressure regulation and fluid containment are critical. This non-vented design prevents external contaminants from entering the reservoir while maintaining a sealed environment for consistent system performance. Whether you're rebuilding a classic muscle car's steering system, upgrading to an aftermarket power steering pump, or maintaining a precision drag racing setup, this cap ensures your hydraulic fluid stays clean and your system pressure remains stable under demanding conditions.

Unlike vented caps that allow atmospheric pressure exchange, the non-vented design creates a sealed system that reduces fluid oxidation and maintains consistent hydraulic pressure across temperature swings—crucial when engine bays reach extreme heat during extended driving or track use. KRC Power Steering is renowned in the street rod and racing community for precision-engineered steering components, and this cap reflects that quality with robust construction that handles both street and competition environments. The compact dimensions (4.55 x 0.85 x 5.85 inches) and lightweight profile (0.18 lbs) make it an easy retrofit for most custom steering setups without adding bulk or weight to your underhood package.

This cap works best with KRC power steering reservoirs and aftermarket hydraulic systems where sealed, pressurized operation is preferred over atmospheric venting. Hot rod builders, engine swap specialists, and racing mechanics rely on non-vented caps to maintain fluid integrity during high-speed cornering, acceleration, and braking events where traditional vented designs may introduce air and moisture. Installation is straightforward—simply remove the old cap and thread this unit onto your reservoir until snug; verify proper fitment before running your system to ensure a leak-free seal.
