Below is a curated look at five relevant options. Each product section includes a quick overview, key features drawn from the listing, and practical notes on where it fits best in typical hydraulic setups.
LOSTAR 6 Quart Poly Power Unit Reservoir
Designed for compact hydraulic systems, this 6-quart reservoir measures 7″ L, 8″ W, and 13″ H with a 4-11/16″ round opening and a 4″ bolt pattern. The polyethylene construction is lightweight yet durable, offering a convenient option for dump trucks, trailers, RVs, boats, and other mechanical vehicles. Features ensure adequate oil storage and supply, while filtering functions help keep hydraulic oil clean and consistent for stable pump operation. Ideal for smaller setups where space is at a premium yet reliable reservoir performance is required.
LOSTAR 4 Quart Poly Power Unit Reservoir
This 4-quart, polyethylene tank provides a compact option for smaller hydraulic circuits in vehicles like tractors and light trucks. Its universal application scope mirrors larger LOSTAR models, with a focus on storing and filtering hydraulic oil to prevent impurities from entering the system. The durable plastic construction keeps weight down while delivering reliable performance in typical field and shop environments where space matters but dependable oil supply is non-negotiable.
LOSTAR 5 Quart Poly Power Unit Reservoir
Offering a 5-quart capacity with similar poly construction, this reservoir balances compact dimensions with practical storage. The 7″ L x 8″ W x 11.5″ H footprint and a 4-11/16″ opening accommodate a range of hydraulic setups from small trailers to utility vehicles. Like other LOSTAR options, it emphasizes clean oil delivery and avoidance of contaminants that could compromise pump performance.
VEVOR Hydraulic Fluid Tank 10 Gal
VEVOR’s 10-gallon hydraulic tank uses a welded steel body with a black powder-coated finish, plus phosphate-coated internal surfaces for corrosion resistance. It features a tank gauge and an oil return filter designed for fast, stable flow. Dual inlet/outlet options (2″ NPT inlet, 3/4″ and 1-1/2″ NPT outlets) and mounting brackets support flexible installation in larger hydraulic systems Commonly used for tractors and trucks, this tank aims to balance capacity, durability, and ease of maintenance in demanding environments.
Field Tuff 10 Gallon Welded Steel Reservoir
Field Tuff’s 10-gallon steel tank emphasizes reliability for wood splitters and other portable hydraulic equipment. The design includes a breather cover on the input port to maintain airflow and minimize moisture ingress, helping to sustain fluid quality during operation. The robust steel construction supports heavier-duty applications while providing adequate storage for longer jobs that demand a steady hydraulic supply.
Delavan HYDRES-5 PowerMAX 5 Gallon Tank
Delavan’s HYDRES-5 PowerMAX provides a 5-gallon capacity with 14-gauge steel construction and standard 1.5″ FNPT inlet and 0.75″ FNPT outlet ports. The thicker wall and sturdy build are suited to long-term use in demanding hydraulic tasks, offering solid durability for frequent pump cycles and varied operating temperatures. This tank is a solid choice for classic hydraulic pump systems requiring dependable, proven hardware.
Buying Guide: Key Purchase Considerations
When selecting a hydraulic reservoir, consider capacity needs relative to pump flow and duty cycle. Larger systems may benefit from 10-gallon steel tanks for durability and extended use, while smaller setups can optimize space with 4-6 quart poly reservoirs. Material choice matters: poly tanks are lightweight and corrosion-resistant, ideal for compact, mobile units; steel tanks offer rugged durability and higher heat tolerance for heavy-duty tasks.
Important features to compare:
- Inlet and outlet sizing: Ensure compatibility with your pump fittings (NPT dimensions vary by model).
- Breather caps and filtration: Breather caps help vent moisture; filtration systems reduce debris that can clog lines and wear pumps.
- Oil level indicators and gauges: Provide quick status checks and help prevent overfilling or running dry.
- Mounting and brackets: Proper mounting reduces vibration and ensures stable operation in mobile or stationary setups.
- Corrosion protection: Powder coating and internal coatings extend life in challenging environments.
For applications involving multiple hydraulic functions, consider a reservoir with a capable filtration system and room for added accessories like strainers or breather caps. Evaluate whether you need a compact, portable tank for on-the-go work or a larger, stationary tank for workshop installations. Finally, verify compatibility with your hydraulic fluid type and the overall system pressure to prevent leaks and ensure reliable performance.
