SmartLine Boulder Swirl Liner

This liner is specifically engineered for 20' x 40' rectangular pools with a 4-foot flat bottom and a standard bead connection. It is also fully compatible with Fanta-Sea Pools, but you should verify your pool's bead type before purchasing to ensure a secure fit.

The 25-gauge thickness provides a robust barrier against everyday wear and tear, such as punctures and abrasions. This thickness is considered a premium standard, offering a balance between flexibility for easier installation and the structural integrity needed to withstand long-term use.

Using 100% virgin vinyl means the material is free from recycled fillers, which can weaken the structure over time. This purity allows the liner to remain flexible and resistant to cracking, especially when combined with the heat-bonded and RF-welded seams that prevent leaks.

The liner is specifically treated to be UV resistant, which helps maintain the vibrancy of the blue stone design. While all vinyl will eventually show some signs of aging, this treatment significantly slows the fading process caused by constant sun exposure.

Because the seams are vulcanized and RF-welded, they are exceptionally strong and do not require special maintenance. However, maintaining proper water chemistry balance is essential for any vinyl liner to prevent premature degradation of the material.
