Abimars 0.7mm Water Tubes for Pool Cover, 10 Pack 8 FT Extra-Thick — Open-Box, 23% Off

Sturdy 0.7mm Triple-Layer Design for Leak-Free Winter Use — Built with inner and outer E-PVC layers plus a fiber-reinforced core, These pool cover tubes are very sturdy and maintain a much more defined shape which helps seal the edges of the cover than thinner 0.4mm 1-layer PVC tubes.

Wider & Heavier for Stronger Hold — Compared to flimsy blue PVC bags, our dual-chamber black pool cover water bags are wider at the same length for greater water capacity and weight. They apply stronger downward pressure and form a tighter seal, which helps prevent the pool cover from being blown off by strong winter winds and protects the pool from costly damage.

Stronger, Safer Welds – No Winter Leaks — Our high-frequency ultrasonic welding fuses materials without damaging their molecular structure, ensuring extra-strong, freeze-resistant seams. Unlike common hot plate welds used in blue PVC tubes, ours won’t crack or leak—giving you long-lasting peace of mind.

Leak-Free Screw Cap Design — Unlike hard-to-use snap-on lids, our pool cover water bags feature a secure screw-on cap with a built-in rubber seal for a tight, leakproof fit. Easier to open and close, it keeps water contained and saves you the hassle of messy spills.

Freeze-Proof & Built to Last — Made with thickened composite materials and ultrasonic heat sealing, our pool cover water tubes stay flexible and leakproof down to -10°F. Built to withstand freezing weather year after year, it saves you the hassle and cost of constant replacements and prevents expensive pool damage.
