Jobox Crescent 100 Gallon Rectangular Tank
The Jobox Crescent 100 Gallon Tank is a steel, rectangular transfer tank designed for trucks. It features internal baffles to improve strength and control flow during movement and 2″ NPT reinforced bungs that support mounting a pump on either side. Built-in lifting rings aid handling when the tank is empty. This setup is ideal for fleets that prioritize durability and pump flexibility. A potential limitation is its heavier steel construction, which may require more mounting support and lifting effort compared to portable options.
Weather Guard 100-Gallon Transfer Tank
The WEATHER GUARD 100-gallon transfer tank is designed for diesel and hydraulic fluids, compatible with most full-size pickups. This tank is described for non-flammable fluids and is positioned as a robust option for vehicle-based transfers. It is best for users who want a conventional, pickup-ready tank with straightforward fluid compatibility. A caution is that it should be used only with fluids specified by WEATHER GUARD to maintain safety and integrity.
Aimery 100 Gallon Diesel Tank Vehicle, Petrol Tank
The Aimery 100-gallon diesel container is a large-capacity bladder designed for high-volume liquid transport. Made from high-density TPU and designed to resist aging, anti-freeze, and corrosion, it features a metal faucet for sealing and easy dispensing. The foldable design saves space when not in use. Best for users needing flexible storage and transport in environments where rigid tanks are impractical. A limitation is that bladder-based systems may require careful monitoring for leaks at joints and ports compared to rigid tanks.
classAcustoms | T-10000 RV Fresh Water 100 Gallon Tank
This Class A Customs 100-gallon tank is designed for RV fresh or gray water and uses NSF-approved materials. It features multiple fittings (six 1.5″ female NPT and additional 0.5″ ports) and flexible orientation, allowing it to sit on any side. It suits RV owners or mobile setups needing a larger capacity tank with built-in connections. A caution is to verify clearance and the exact mounting geometry to avoid interference with RV components.
ZSLTLDU 100 Gallon Water Bladder
The 100 Gallon Water Bladder from ZSLTLDU is a foldable, portable water tank constructed from 1000D PVC. It offers leak resistance and UV stability, suitable for camping, agriculture, or emergency water storage. A key advantage is portability when space is limited. A potential drawback is that, as a bladder, it may require extra care to prevent punctures or leaks during transport in rugged environments.
Benut Oil Tank Gauge for 275 & 330 Gallon Tanks
The Benut oil tank gauge targets 275 and 330 gallon vertical tanks with a clear dial window and compatible 1.5″ and 2″ NPT openings. It provides a straightforward way to monitor oil levels in larger tanks. Best for homeowners upgrading an older gauge or seeking a replacement. A limitation is that it is a gauge only and must be paired with an appropriate tank, not a standalone tank solution.
Buying Guide
What should you consider when choosing a 100-gallon tank for oils, diesel, or water?
- Tank material and durability: Steel tanks like Jobox offer strength and long life, while bladders and PVC bags save space but may require gentler handling.
- Intended use: Vehicle-based transfers benefit from rigid, mounted tanks; portable bladders suit temporary storage or emergency kits.
- Fittings and compatibility: Check the number and size of NPT ports and whether pre-installed baffles or mounting options exist.
- Mobility and installation: Consider whether the tank will be moved often or stays in one place; lifting rings, wheels, and mounting hardware affect setup.
- Fluid type and safety: Ensure materials match the fluids (oil, diesel, water) and adhere to safety guidelines for handling flammable liquids.
- Storage conditions: For outdoor use, UV resistance, weather sealing, and temperature tolerance are important.
