Product Information

Specification

Enhance Winter Pool Security :

This 12-pack of 8 × 0.94 ft double-chamber pool cover water bags provides reliable weight to keep your pool cover securely in place throughout winter, preventing wind lift and debris from entering the pool. Ideal for in-ground pools, these bags are easy to fill, drain, and store—saving you time and effort during winter cleanup.

Double-Chamber Anti-Roll Design :

The pool cover water tubes feature a stable double-chamber construction that prevents rolling or shifting, even during strong winds or heavy storms. They ensure your pool cover stays firmly positioned, making seasonal maintenance simpler.

Thick 0.4 mm PVC Material :

Made from durable and flexible 0.4 mm PVC, these winter water tubes resist UV damage and minor impacts. When filled to 50–70% capacity, they provide balanced weight while leaving room for expansion—minimizing the risk of bursting due to temperature fluctuations. Suitable for year-round outdoor use.

Heavy-Duty Welded Seams :

Each water tube includes high-frequency heat-sealed edges with wide 0.59-inch seams for superior leak resistance and long-lasting durability. They are designed to withstand both intense sunlight and freezing winter temperatures without cracking or aging.

Leak-Proof Twist Cap :

Each bag is equipped with an easy-turn twist cap with a built-in rubber gasket to ensure a tight, leak-proof seal. The anti-loss tether keeps the cap attached, while the improved twist design offers better sealing and convenience than traditional snap caps.
Tip: Before filling, slide the retaining ring to the bottom of the spiral thread for the best seal.
