Swimline LI183352MGU Oval Mystri Gold Unibead Above Ground Liner - 18 ft x 33 ft, 52 in Wall

What This Part Is Used For
This unibead liner replaces the interior vinyl surface of an 18 ft x 33 ft oval above ground pool with 52 in wall height. It installs into a bead receiver track and forms the watertight barrier that holds pool water. It is used during full liner replacement for residential above ground pool systems.

Why This Part Matters
Oval pools put extra demand on liner fit across long straight runs, so wall height and sizing have to be right. A mismatched liner can wrinkle, shift, or stress seams as the pool fills. The correct liner helps the pool set cleanly and prevents water intrusion that can damage the wall structure.

About the Swimline Brand
Swimline provides liner options for above ground pool owners who want a reliable, serviceable replacement sized for common backyard pools. Their unibead liners integrate with bead receiver tracks for a clean top rail finish and easier future service. Swimline is frequently used in seasonal replacement work because the sizing is straightforward when measurements are confirmed up front.

Common Service Context
This liner is most often installed when the existing liner has seam leaks, heavy fading, or floor wrinkles that will not reset. Oval pool liner replacements are commonly scheduled for spring openings and mid-season repairs when a leak becomes unmanageable.
