VEVOR 365.7 cm Pool Liner, Round Overlap Swimming Pool Liner for 90 cm Wall Height, Premium Vinyl, Easy Install with Leak-Proof Patches, Designed for Steel Sided Above-Ground,Outdoor, Blue

365.7 cm Precision Fit with the 12 ft Round Pool Liner Built for Zero Wrinkle Overlap Installation

This 12 ft round pool liner is designed for φ365.7 cm round pools. It is sized to help reduce wrinkles and folds during installation. The snug fit around the edges ensures there are no dead zones where water can get under the liner or cause stress-related tearing over time.

Installing without wrinkles isn't just for looks; it's for the structure. Folds trap sediment, accelerate UV damage at contact points, and initiate micro-tears under hydraulic pressure. VEVOR's overlap design locks the liner to the pool wall, evenly distributing tension and keeping the surface intact across the full 365.7 cm diameter during use.

0.4 mm Thickened PVC Vinyl Construction Engineered for Puncture and Tear Resistance

This high-quality vinyl pool liner has a thickness of 0.4 mm, exceeding the entry-level market standard of 0.2–0.3 mm. This feature makes it more resistant to punctures, abrasions, and tensile stress during normal pool use. The material compound is designed to bend without fatigue, reducing the risk of cracks spreading under load cycling.

The thickened PVC construction is the most important factor in prolonging the liner's lifespan. Thinner liners lose plasticizer content more quickly when exposed to UV light and chlorine, and they become brittle within one to two seasons. The 0.4 mm gauge gives you a lot more service life per dollar, which is the most important performance spec when calculating the total cost of ownership.

90 cm Steel Sided Wall Compatibility with Structural Fit for Standard Above Ground Pool Frames

This 12 ft round pool liner is designed for walls 90 cm high, which is the standard size for steel-sided above-ground pools in the mid-size residential category. The overlap cut accounts for the full 90 cm vertical drop and the top-rail drape allowance. It keeps the liner from slipping when there is a lot of water on it.

Most buyers don't think about wall-height compatibility until the day of installation. If a liner is too short for a 90 cm wall, it will pull away from the top rail under water pressure. It will expose the steel wall to corrosion and create leak paths at the bead channel. For a watertight, professional-grade installation, getting the vertical dimensions right is a must.

12 ft Round Pool Liner Leak Proof Patch System Included with Field Repairable Vinyl Rated for Underwater Application

This pool liner comes with leak-proof factory-matched patches, so you can fix small holes without draining the pool. The patch material is the same as the base vinyl compound, so that the adhesive bond strength won't be affected by a mismatch in the substrate. It is a common problem with third-party repair kits.

Field repairability directly increases the liner's operational lifespan. A single unpatched pinhole can grow into a structural split in just one season if it is under 90 cm of hydrostatic pressure. If you have manufacturer-spec patches, apply them right away to fix minor damage. It keeps the water chemistry balanced, protects the steel pool frame, and saves you money by preventing the need to replace the whole liner.

All-Season UV and Low Temperature Resistance with Outdoor Rated Flexibility Below Freezing

This pool liner is designed for year-round outdoor use. It stays flexible even when it's cold, so that it won't break or crack on the surface. The PVC formulation helps slow UV-related material degradation, which is the main reason outdoor pool liners lose color and become chalky after prolonged exposure to the sun.

Above ground pools in climates that change a lot undergo thermal cycling regularly, expanding in the summer heat and contracting in the cold. It puts a lot of stress on the liner's seams and edges. If a liner loses its flexibility when it's cold, it will crack along the fold lines when you store it in the winter or fill it up in the spring. VEVOR's all-season compound stays stable in size no matter what the temperature is outside, so that you can protect your investment through many seasons.

Matte Anti-Slip Backing and Polished Interior Surface with Dual Texture Engineering for Safety and Hygiene

The inside has a smooth, polished finish that makes it hard for biofilm to stick to it and makes it easier to brush and vacuum during regular cleaning. The matte backing provides surface grip on the pool floor, keeping the liner from moving around when people are using it and when they enter or leave.

Moving the liner is a safety and structural issue. A liner that moves around bunches up at the base of the pool, making it easy to trip, and unevenly distributes hydraulic pressure across the steel wall. The anti-slip backing helps reduce this issue by keeping the 12 ft round pool liner in place even when the water is moving, and people are walking on it. It doesn't need any extra glue or mechanical fastening.

Chlorine and Chemical Resistance with PVC Compound Rated for Standard Pool Water Treatment Cycles

This vinyl pool liner is designed to withstand normal chlorine levels and the chemical changes that occur during regular pool water treatment, including pH adjustments, algaecide additions, and shock dosing. Chemical breakdown in low-quality liners manifests as surface stickiness, delamination, and accelerated plasticizer loss, all of which make the water less safe and the structure weaker.

For pools in backyards and gardens where the water chemistry changes with the seasons, chemical resistance is a basic need, not a luxury. VEVOR's PVC compound maintains the pool's surface integrity during normal treatment cycles. It supports liner durability, protects the pool's steel sides from corrosive contact, and ensures the liner looks finished and professional throughout its use.
