Red Lion RL2A 2-Gallon Inline Tank
The Red Lion RL2A is an inline, pre-charged pressure tank designed to support well pump systems and reduce water hammer. It features a heavy-duty 20-gauge steel body and a 304 stainless steel water connection with a patented leak-safe design. The diaphragm uses high-performance butyl rubber, paired with a polypropylene liner for durability and clean-water compatibility. It is pre-charged to 20 PSI during transport, and setup requires topping off air pressure to 2 PSI below the pressure switch cut-in setting. This model is certified for safe, drinking-water use, making it suitable for residential wells and small pressure-boost systems.
Key features include: pre-charged construction, durable steel tank, stainless water connection, leak-safe technology, and a diaphragm designed for longevity. It is well-suited for reducing cycling strain on pumps and maintaining steady pressure in compact home systems.
VEVOR Hydraulic Fluid Tank 10 Gal
Although listed at 10 gallons, this compact hydraulic reservoir is designed for compact installations and can be repurposed in smaller hydraulic transfer setups where space is at a premium. It is constructed from cold-rolled steel with a black powder-coated exterior and phosphate-coated internals for corrosion resistance. The tank includes an oil level indicator and a gauge, an oil return filter, a breather cap to filter impurities, and multiple NPT ports (2″ inlet, 3/4″ and 1-1/2″ outlets). Mount brackets facilitate secure placement. It provides robust storage and transfer capacity for larger hydraulic systems while still fitting into tighter spaces than bulkier tanks.
Considerations include its larger capacity relative to 2 gallons, corrosion protection features, and port configurations that support versatile plumbing and mounting options.
Besttruck 5 Gallon 14 Gauge Tank (Selected for Reference)
This variant is a 5-gallon model, offered here for context when comparing tank sizes. It is a 14-gauge welded steel reservoir with a 2-inch suction port and 0.75-inch return port, plus a mounting end foot. It demonstrates how larger storage capacities translate to longer run times between refills and more stable pressure in larger hydraulic systems. While not a 2-gallon unit, understanding its construction and port layout helps in choosing compatible components for similar applications.
Viair 2.0 Gallon Tank
The Viair 2.0 Gallon Tank is a compact reservoir rated for up to 150 PSI and equipped with six 1/4 inch NPT ports. This design supports multi-connection configurations, enabling integration with various pneumatic and hydraulic lines in portable systems or compression setups. It includes mounting hardware and isolator bushings for stable installation. The multiple ports provide flexible routing options for air and fluid lines in tight spaces, making it a strong candidate for shop and on-vehicle projects where space is critical.
Speedway 2 Gallon Aluminum Tank
The Speedway 2-Gallon Aluminum Seamless Tank is a lightweight, corrosion-resistant option crafted from seamless aluminum. It comes with mounting brackets and hardware for easy installation and is rated to 200 PSI. This tank is well-suited for automotive, automotive-adjacent, or compact portable air systems where weight savings and quick mounting are priorities. The aluminum construction helps in reducing corrosion risks in humid environments and provides a durable, maintenance-friendly reservoir for compressed air applications.
WaterWorker 2-Gallon Expansion Tank
The WaterWorker 2-Gallon Expansion Tank is NSF-listed under ANSI/NSF Std 62, with a butyl diaphragm designed to flex rather than crease and a polypropylene liner that resists flaking and odor transfer. This model is intended for potable water expansion and is designed to avoid taste and odor contamination. The tank is compact and durable, ideal for small residential water-heating or water-treatment systems where expansion control is needed without introducing contaminants into the water supply.
Hydraulic Power Unit 12VDC, 2 gal Tank
The Fluidhaus Hydraulic Power Unit combines a 2.6 HP, 12V DC motor with a compact 2-gallon reservoir. It offers adjustable pressure settings and optional valve configurations (VSD6 options) to tailor output for hydraulic tasks such as lifting, clamping, or small machine actuation. This unit can be powered from a battery or vehicle electrical system, making it suitable for portable hydraulic operations or remote-locations where a stationary power supply is unavailable. The compact footprint supports integration into wheeled carts or tool benches.
Buying Guide
- Capacity and application: Match tank size to your system’s demand. A 2-gallon tank provides quick response for smaller pumps or portable setups but may require more frequent cycling in high-demand operations.
- Materials and durability: Steel tanks offer strength and durability, while aluminum tanks save weight. For potable water applications, ensure NSF/ANSI listings and compatibility with your water system.
- Pressure rating and ports: Check maximum operating pressure and available ports. Tanks with multiple NPT ports provide flexible plumbing options for complex lines and accessories.
- Diaphragm and liner quality: A robust diaphragm reduces pulsation and water hammer. Liner material should resist chemical exposure and not impart taste or odor in potable uses.
- Installation considerations: Inline tanks can be mounted on pumps or lines; freestanding reservoirs may require brackets. Consider space, mounting options, and vibration isolation when selecting a location.
- Maintenance: Look for tanks with easy access to pressure settings, and diaphragms that are replaceable. Regular checks for leaks and corrosion extend service life.
- Portability vs. permanence: Lightweight aluminum models are easier to relocate, while steel and composite tanks are typically more rugged for permanent installations.
- Energy and efficiency: In hydraulic systems, select a tank size that minimizes cycling and maintains steady pressure to reduce wear on pumps and valves.
