UL-142 Single Wall Horizontal Skid Tanks for Aboveground Fuel Storage

A UL 142 tank is a shop-fabricated, aboveground steel tank used for storing flammable and combustible liquids where listed equipment is required or preferred. Mills Equipment offers UL-142 single wall horizontal skid tanks for fueling operations that need a strong, serviceable tank layout, and the build standards outlined in Why Choose Mills? help explain what you are buying.

What Is UL 142 and When Is It Used?

Many buyers search “UL-142 tank” when a project spec or inspector calls for a recognized aboveground tank standard. The summary in UL142 Aboveground Flammable Liquid Tanks explains what UL 142 covers, and your authority having jurisdiction should confirm what applies at your site.

Choosing Single Wall vs Double Wall

Single wall UL-142 skid tanks are often used when secondary containment is handled at the site level or allowed by local requirements. If built-in containment is required, compare the UL-142 Double Wall Horizontal Skid Tank for Fuel Storage option, and use UL-2085 vs. UL-142: Which Certification Is Right for Your Tank? when you need to evaluate UL-2085 Fireguard Tanks for higher protection.

UL 142 Tank Sizes, Dimensions, and Planning

Use the size chart on this page to compare UL-142 horizontal skid tank capacities and dimensions across common and build-to-order ranges. For footprint and volume planning, the Tank Capacity Charts for Fuel Storage resource supports layout and delivery prep, and the 550 UL 142 Single Wall W/ 3 Options listing is a practical reference point for many fueling setups. For pricing on larger builds, Contact Us early to confirm availability and freight planning details.

Common Uses for UL-142 Skid Tanks

UL-142 single wall skid tanks are commonly used for diesel or gasoline storage in:

  • fleet yards and maintenance shops

  • construction and jobsite fueling points

  • farms that require listed aboveground fuel storage

If your footprint favors vertical storage, UL-142 Single Wall Vertical Fuel Storage Tanks can be a better fit for some bulk installations.

Pumps, Vents, Gauges, and Dispensing Add-Ons

Build a complete fueling system with compatible components, starting with Transfer Pumps, Hand Pumps, & Fuel Equipment options. Finish the setup with Fill Caps, properly sized Vents, and Fuel Tank Gauges & Mechanical Level Monitoring, then add Filters & Filter heads and clear Decals when your standards call for them.

Secondary Containment and Site Compliance

When a berm or dike is part of the plan, Containment Dikes options support secondary containment goals while you follow local requirements.

UL-142 Tank FAQs

Do UL 142 tanks require specific venting or emergency vents?

UL 142 tanks are designed with defined openings and venting requirements based on fuel type and code expectations. Proper vent sizing and configuration are critical for safe operation, so review compatible components in Vents and confirm requirements with your authority having jurisdiction before installation.

How do I determine the right UL 142 tank capacity for my operation?

Start by estimating average fuel consumption, delivery frequency, and available site space. The sizing guidance in Understanding Tank Sizing: Finding the Right Fit can help you narrow down options, and the Tank Capacity Charts for Fuel Storage page provides quick reference dimensions for planning.

Do I need a double wall tank? 

Some sites do, so confirm requirements and review the UL-142 Double Wall Horizontal Skid Tank for Fuel Storage details for comparison.
