Filling Bottle XSPC LDPE 1000 ml — coolant refill container for PC liquid cooling

The XSPC LDPE filling bottle 1000 ml is a refill and transport container designed for topping up and maintaining PC liquid cooling systems. Made from low-density polyethylene (LDPE), the bottle provides flexible walls and controlled pouring for precise refills of radiators, reservoirs and other loop components. Its 1-litre capacity accommodates full top-ups or partial fluid changes, and the material choice reduces the risk of chemical interaction with common coolant formulations.

Advantages

The bottle's LDPE construction combines flexibility with chemical compatibility for most water-based and glycol-based coolants, enabling controlled dispensing and minimizing spills. A screw-top design and tapered nozzle allow for steady flow into tight filling ports without excessive splashing, while the translucent body helps monitor remaining fluid. The 1000 ml volume is practical for maintenance sessions and transport of prepared coolant.

Suitable for

• Refilling PC liquid cooling radiators and reservoirs
• Performing coolant changes and top-ups
• Transporting prepared coolant to the worksite
• Leak testing and controlled pouring during loop assembly

Key specifications

• Capacity: 1000 ml
• Material: low-density polyethylene (LDPE)
• Translucent body for fluid level visibility
• Screw cap with tapered pouring nozzle for controlled flow
• Flexible walls to support gentle squeezing and flow control

How to use

Fill the bottle with prepared coolant, ensuring no contaminants enter the container. Secure the screw cap and, if present, attach the pouring nozzle. When refilling a loop, position the nozzle into the radiator or reservoir fill port and squeeze gently to introduce coolant while avoiding air ingestion. Refill slowly until the loop is primed and all air pockets are removed, then close the system and inspect for leaks.

Usage recommendations

Use the bottle for water-based and most glycol-based coolants; avoid storing strong solvents or aggressive chemicals. Clean the bottle thoroughly before changing coolant types to prevent cross-contamination. Store upright in a cool, shaded place and replace the bottle if the material shows signs of cracking or severe deformation.
