Thicker Black Water Tube for Pool Covers, 6 Pack of 8 FT Water Weight Bags for Pool Side, Three-layer Composite Material: Ideal for Winter Swimming Pool Maintenance.

About this item

• Made from 3-layer composite materials: Crafted with E-PVC on upper/lower layers and a fiber explosion-proof middle layer. These sturdy tubes hold their shape better, sealing edges more effectively than thinner 0.4mm single-layer PVC tubes
• Our single-chamber black water tubes have higher water capacity and weight for superior ground pressure and a better seal. Their virtually seamless design reduces the risk of leaks, providing a more reliable option than seamed tubes
• High-frequency welding: Our water bags feature high-frequency welding and wide seams for airtightness and pressure resistance. Withstand -10°F (-25°C); fill 2/3 full to avoid freeze expansion. Enjoy over 2 years of durability in cold conditions
• Screw Tops: Our water bags feature a screw-on cap, unlike the tricky snap-on style. Easy to use and secure, the screw cap includes a rubber seal to prevent leaks, making it more user-friendly and convenient for keeping water contained
• Effortless Setup: Winterizing is easy with single-chamber water tubes; one fill does it all. Their flexible design bends around curves, perfect for rounded pools. Get optimal edge coverage, unlike double-chamber bags with design limits
