Inspection-Ready Venting, Spec'd Correctly Before It Ships

Inspection-Ready Venting, Spec'd Correctly Before It Ships

A non-compliant vent is the kind of detail that fails a fire marshal walkthrough — not because the tank is wrong, but because one component doesn't carry the right UL listing. That's exactly the failure Tank Vault eliminates. We verify compliance requirements for your state and application before the order ships, so the vent that arrives matches your tank's code class. This Clay & Bailey emergency vent carries UL-142, UL-2085, UL-2244, UL-2583, NFPA 30, 30A, and API 2000 listings — covering the standards that matter for aboveground fuel storage. Spring-actuated with a 0.5 PSI set point and full open at 2.5 PSI, it delivers code-compliant pressure relief without guesswork.

All-Aluminum Build That Outlasts Steel in the Field

All-Aluminum Build That Outlasts Steel in the Field

All-aluminum construction eliminates the rust problem that plagues steel vents on exposed tank installations. Scratches from handling, weather exposure, and years of thermal cycling don't degrade this vent body — because there's no steel to corrode. The Buna N O-ring provides a vapor-tight seal that holds up under repeated pressure cycles, and the lightweight design makes installation straightforward without sacrificing structural integrity. For fleet yards, construction sites, and municipal fuel installations where the vent sits exposed year-round, aluminum is the industrial-grade choice. This vent is built to last as long as the tank it protects.

Spring-Actuated Accuracy at the Pressures That Matter

Spring-Actuated Accuracy at the Pressures That Matter

Pressure relief isn't optional — NFPA 30 requires it, and your fire marshal will check it. This vent uses a spring-actuated mechanism set to open at 0.5 PSI and reach full flow at 2.5 PSI, delivering consistent relief without drift or manual adjustment. The spring design maintains accuracy across temperature swings, so the vent performs the same in August heat as it does in January cold. Available in male thread sizes from 2 to 8 inches, it fits standard aboveground storage tank configurations where code-compliant emergency venting is required. No field calibration needed — install it, and it's spec'd to perform.

“Ordered the 4-inch male vent for our 2,000-gallon diesel skid tank. Fire marshal approved the installation on first walkthrough — UL listing sheet was in the box, no follow-up calls needed. Tank Vault confirmed the size was right for our fill rate before I placed the order.”

    Frequently Asked Questions

    This Clay & Bailey emergency vent is listed to UL-142, UL-2085, UL-2244, and UL-2583, covering standard aboveground storage, Fireguard-rated, generator base, and mobile equipment applications. It also complies with NFPA 30, NFPA 30A, PEI RP200, and API 2000. Every order ships with the applicable documentation — no chasing the manufacturer after delivery.
    Vent sizing depends on your tank capacity, fill rate, and the specific NFPA 30 requirements for your installation. This vent is available in 2, 3, 4, 6, and 8-inch male thread sizes. If you're unsure which size matches your tank's venting requirements, contact Tank Vault before ordering. We run a free pre-offer spec review to confirm the right size for your application — so you don't end up with a vent that's undersized for your fill rate.
    Yes. The vent carries listings for both UL-142 and UL-2085, so it works on standard double-wall aboveground tanks and Fireguard-rated installations. The all-aluminum construction and Buna N O-ring seal perform across both tank types without modification. That said, always verify vent sizing against your specific tank's requirements — NFPA 30 calculations vary by capacity and fill rate. Contact us with your tank specs and we'll confirm fitment before you order.
    The spring-actuated mechanism is set to begin relieving pressure at 0.5 PSI and reaches full open flow at 2.5 PSI. These are factory-calibrated settings — no field adjustment is required. The spring maintains consistent opening pressure across normal temperature ranges, so you get reliable performance without drift. This matches the emergency venting requirements outlined in NFPA 30 and API 2000 for aboveground storage tank applications.
    This vent ships free via standard LTL or parcel carrier depending on your order. Lead times vary by size — contact us with your required delivery date and we'll confirm availability before you order. If you have a fire marshal deadline or compliance inspection coming up, let us know upfront. We prioritize getting documentation and hardware to your site on schedule.
    Same product, same manufacturer — but we add pre-offer compliance verification. We confirm the vent size and UL listing match your tank type and jurisdiction before the order ships. You also get full documentation included with delivery, and a team that speaks NFPA 30 and EPA SPCC. If you're unsure whether you need a 2-inch or 4-inch vent for your installation, we'll run the spec review at no charge.
