Why Choose the RY3463?

  • Extended Reach: The 13mm fin provides an extra 3mm coverage compared to VH009 T-seals.

  • Compact Efficiency: At 950mm, it is the ideal size for a standard British shower door or bath screen.

  • Low-Profile Base: The 8mm T-base allows for a discreet bond on narrow glass edges.

  • Multi-Surface Bond: Engineered to adhere firmly to glass, acrylic, and ceramic surfaces.

Detailed Description

The RY3463 is a high-performance alternative for those dealing with "awkward" bathroom leaks. If your shower door sits slightly too high from the tray, the 13mm extended fin effectively bridges that void to stop spray from escaping.

Its 8mm T-section provides a stable foundation for the high-strength adhesive backing, ensuring the seal remains locked in position despite daily use. The 950mm length is specifically chosen to cater to the most common UK shower door widths.

Like all SIMBA professional seals, it is crafted from UV-stable PVC to prevent the premature yellowing caused by bathroom lighting and humidity.

💡 Pro Tip for a Permanent Seal:

For a flawless finish on a standard bath screen, align the RY3463 so the 13mm fin just brushes the surface of the tub. Allow 8–10 hours for the adhesive to cure before the first shower.

8mm Self-Adhesive T-Shape Seal | 13mm Extended Fin | RY3463 Installation Guide - Simba Anti-Mould Shower Seal

✓ DO’S

  • Direct Press: Fit by pressing directly onto the glass edge to protect the surface.
  • Deep Clean: Remove all UK hard-water limescale before installation.
  • Sharp Tools: Use garden pruners for a clean, professional finish.
  • Daily Rinse: Simply wash away soap suds after your shower.

✕ DON’TS

  • No Sliding: Never slide the seal along the glass; this risks scratching.
  • No Extreme Heat: Avoid water >70°C or hair dryers to prevent warping.
  • No Soapy Water: Do not use lubricants—they accelerate mould growth.
  • No Harsh Chemicals: Avoid bleach or acidic cleaners on the seal.
