OCOCOO 50mm External Thread Reservoir

The Core of  Liquid Cooling System

The OCOCOO 50MM External Thread Reservoir is a professional-grade cooling component designed for high-performance computing and industrial applications. In any liquid cooling loop, the reservoir serves as the "lungs" of the system—managing coolant levels and purging air bubbles. Our reservoir is engineered to solve the most common pain points in the industry: leakage, micro-cracks, and air-binding.

Whether you are a gaming PC modder, a server technician, or an industrial system integrator, our cylindrical PMMA tank provides the reliability and visual clarity required for high-stakes thermal management.

Key Selling Points 

• Innovative External Thread Design: Most reservoirs use internal threads which can put stress on the acrylic tube, leading to "silver temperature cracking" over time. Our external thread design at both ends of the acrylic part significantly reduces structural stress, ensuring your system remains leak-free even under varying temperature cycles.
• Built-in Diversion & De-foaming Pipe: Air bubbles in a loop can cause pump cavitation and noise. Our reservoir features a built-in diversion pipe that breaks surface tension, facilitating rapid de-foaming. This results in a quieter system and improved energy efficiency by reducing water resistance.
• One-Piece High-Impermeability Fabrication: We utilize a one-piece fabrication process for the POM and Acrylic parts. This "monolithic" approach ensures higher impermeability compared to low-end glued alternatives, protecting expensive hardware from moisture or catastrophic leaks.
• Universal G1/4 Connectivity: To ensure maximum compatibility, the top and bottom lids feature standard G1/4 threads. This allows seamless integration with any standard liquid cooling fittings, pumps, and tubing on the market.
• Transparent Visual Clarity: Made from premium clear acrylic (PMMA), our reservoir offers a 360-degree view of the coolant flow, making it easy to monitor liquid levels and add a premium aesthetic to any custom build.

Multi-Scenario Application Descriptions

• Custom Gaming PCs: The 96mm compact version is perfect for ITX and small-form-factor (SFF) builds where space is at a premium. The clear PMMA showcases RGB coolants beautifully.
• High-End Workstations & Rendering Nodes: For multi-GPU workstations, the 161mm version provides a larger coolant buffer, helping to stabilize temperatures during long rendering or AI training sessions.
• Server & Data Center Cooling: In high-density server racks, the built-in de-foaming pipe ensures that the cooling system remains quiet and efficient, reducing the risk of pump-related downtime.
• Laboratory & Medical Equipment: The high impermeability and chemical resistance of POM/PMMA make these reservoirs suitable for precise cooling in laboratory environments where reliable thermal control is mandatory.

FQA

Q: Does the reservoir include mounting brackets?

A: Our standard wholesale package includes the reservoir and G1/4 plugs. Mounting clips and brackets are available as optional accessories to fit different chassis layouts.

Q: Can I customize the length of the acrylic tube for an OEM order?

A: Yes! As a professional manufacturer, we support ODM customization. If you require a specific height or custom-branded lids, please contact our engineering team.

Q: How do I clean the reservoir?

A: Use only distilled water or mild soap. Avoid using alcohol or ethanol-based cleaners, as they can cause acrylic to craze and crack.

Q: What is the maximum operating temperature?

A: The POM/Acrylic combination is rated for continuous use up to 60°C (140°F), which is well above the typical operating range of liquid cooling systems.

Q：Does OCOCOO ship internationally for bulk orders?

A：Yes, we provide reliable global logistics services, supporting bulk international exports with optimized packaging to prevent damage during transit.
