What makes BU004 different? (Click to expand) ↓
  • The "silicone" feel: Ultra-soft compression for a quiet, cushioned close.
  • Wide-track specialist: Designed specifically for 10mm wide-groove frames, ensuring a snug fit without messy adhesives.
  • Zero-yellowing formula: UV-stabilised hybrid vinyl maintains crystal-clear transparency for years.
  • High-compression recovery: "Remembers" its shape better than standard plastic for a superior watertight seal.

⚠️ Measurement warning (The 10mm check)

  • The base is wide: This seal has a 10mm T-post. It will NOT fit standard 6mm or 7mm grooves.
  • Pro-tip: If your old seal slides around or falls out, you likely need this wider 10mm base. Please measure the internal groove width before ordering.

10mm Wide-Track Bulb Seal - The "Soft-Flex" Silicone Alternative BU004 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.
