Flow Security Systems VersaLock Non-Vented Cap (FSS 750)
The VersaLock non-vented cap provides a quick, cost-effective shield against theft, tampering, siphoning, and vandalism for above-ground and transfer fuel tanks. It features a patented free-spinning design to deter forced entry and can be keyed alike or differently to suit security needs across multiple tanks. The weatherproof latch helps keep dust, debris, and moisture out of the lock face, maintaining reliability in outdoor environments.
Flow Security Systems VersaLock Non-Vented Cap (FSS 750, Quick Fill)
The Quick Fill variant keeps transfer fuel secure while enabling efficient fueling operations. Designed for mobile transfer tanks and above-ground storage, it includes a weatherproof, self-closing latch to prevent contaminants from entering the lock area. Keys can be keyed alike for multiple tanks or differently for added security, making it suitable for fleets or facilities with several vessels.
Flow Security Systems VersaLock Non-Vented Cap (FSS 750, 2CT)
This version supports dual-cap configurations for two tanks, offering the same free-spinning design and secure locking mechanism. Its keyed-alike or keyed-differently options help manage multiple caps across a fleet, simplifying access control while protecting costly fuels from unauthorized use and potential vandalism.
Flow Security VersaLock 754 Vented Cap
Vented VersaLock caps allow controlled venting for transfer and above-ground tanks while maintaining secure access. The self-closing weatherproof latch protects the locking face from dust and moisture, and the system supports either uniform keying or individual keys for enhanced security across multiple tanks—ideal for businesses with diverse tank configurations.
Husky Sentry Tank Alarm (Model 007670)
The Husky Sentry Tank Alarm provides reliable fluid level monitoring for oil, diesel, antifreeze, water, and other liquids. Real-time audible alerts help prevent spills and downtime by signaling low or high levels. Battery-powered operation enables remote deployment in locations without convenient AC power, with optional upgrades for broader power options.
VEVOR 25 Gallon Waste Oil Drain Tank
Note: This item is a waste oil drain tank rather than a storage tank, but it complements above-ground oil operations by enabling efficient waste oil drainage and transfer. It features a height-adjustable funnel and mobility with wheels, supporting convenient handling in auto repair or maintenance settings where oil management is ongoing.
Buying Guide
Key purchase considerations include: tank type compatibility (vented vs non-vented caps), number of tanks to secure, and whether you need interchangeable keys for fleet efficiency. For monitoring, assess alarm features (audible alerts, battery life, auto shutoff options) and ease of installation. Durability in outdoor conditions, weatherproof design, and resistance to dust and moisture are essential for long-term reliability. Evaluate whether you prefer keyed-alike security for multiple tanks or individual keys for higher security. Budget, maintenance needs, and potential integration with existing security systems should also guide your decision. Compare total cost of ownership, including replacement parts and warranties, to ensure sustained protection for your above-ground oil assets.
