Eliminate Fuel Theft Risk With Correct Cap Fit
Fuel theft at fleet yards isn't a minor inconvenience — it's a direct hit to your operating affordable and a compliance headache if your fuel inventory logs don't match. The ATI Spin Secure Refueling Tank Cap locks down your fuel with a keyed mechanism built specifically for ATI refueling tanks. At Tank Vault, we verify your tank model and cap compatibility before the order ships — so you don't end up with a cap that doesn't thread correctly or leaves your fuel exposed. This isn't a generic hardware-store cap. It's a built-to-spec locking cap for operations that can't afford unauthorized access.
Keyed Protection That Holds Up on the Job Site
A locking cap only works if it fits your tank and holds up under daily use. The Spin Secure cap provides keyed protection built specifically for ATI refueling tanks — not a generic fit that leaves gaps or loosens over time. On fleet yards and job sites, fuel access control is a daily requirement, not a nice-to-have. For fleet managers running multiple refueling tanks, using a purpose-built cap eliminates the mismatched hardware from generic replacements. This is a field-proven approach to securing what your operation depends on.
Direct Replacement That Keeps Your Fuel System Covered
When a tank cap goes missing, your fuel is exposed and your compliance window narrows. The ATI Spin Secure Refueling Tank Cap is designed as a direct-fit replacement for ATI refueling tanks, restoring access control without modifications to your existing setup. At Tank Vault, we carry this cap because it matches the standard that ATI tanks are spec'd to — so you receive a cap that fits your tank, not a close-enough substitute from a generalist catalog. One less variable to worry about on your fuel system.

★★★★★
“Ordered this cap after our original went missing between shifts. Fit our ATI tank perfectly — no adapter needed, no threading issues. Keyed mechanism feels solid, not like the flimsy hardware-store replacements we've tried before. Tank Vault confirmed it was the right fit for our model before I even placed the order. That's how it should work.”
Frequently Asked Questions
This cap is designed specifically for ATI refueling tanks. We cannot verify fitment on non-ATI models, and using an incorrect cap creates real risk — improper threading can cause leaks and compromise your fuel system. If you're unsure whether your tank is an ATI unit, check the tank's data plate or manufacturer label before ordering. For non-ATI tanks, contact us with your tank model and we'll help you identify the correct cap. We don't guess on fitment — that's how fuel gets exposed.
Yes. The ATI Spin Secure Refueling Tank Cap ships with a keyed lock mechanism — the key is included with every cap at the time of shipment. If you're ordering multiple caps for a fleet and need to confirm keying consistency, or if you require additional keys, contact Tank Vault before placing your order. We'll coordinate with the manufacturer to confirm what's available. Don't assume all caps arrive keyed alike — verify before you order.
This cap ships free to your location. Standard delivery times vary based on your location and current inventory levels. If you need this cap by a specific date — for example, before a compliance inspection or a job site mobilization — contact us before ordering and we'll confirm availability and estimated delivery. We don't overpromise lead times. If we can't meet your deadline, we'll tell you upfront.
A locking fuel cap supports fuel security and can be part of your site's overall SPCC plan, but it is not independently an EPA compliance requirement. EPA SPCC regulations focus on secondary containment, tank integrity, and spill prevention — not cap type. However, many jurisdictions and company policies require locking caps as an access control measure. Check with your environmental compliance officer or local AHJ to confirm whether a locking cap is required at your installation.
If the cap doesn't fit your ATI refueling tank, contact Tank Vault immediately. We offer a 30-day return window on uninstalled items in original packaging. However, fitment issues are exactly why we recommend confirming your tank model before ordering. If you provide your ATI tank details upfront, we'll verify compatibility before the cap ships — so you don't end up with a return freight situation that costs you time.
Yes. Tank Vault supports industrial and municipal buyers with PO and net-30 terms where applicable. If your fleet operation, fire department, or municipality requires purchase order processing rather than online checkout, contact us with your organization details and we'll set up the order accordingly. We work with government and commercial accounts regularly — this is standard procedure, not an exception.
