2 Inch Durable Rubber Toilet Flapper

A 2-inch universal toilet flapper made from high-compliance soft rubber and fitted with a corrosion-proof stainless steel chain. Dimensions: 50 mm diameter × 10 mm thickness; weight: 20 g. Compatible with standard 2-inch flush valves used in most British Standard (BS EN 14055) and EU-certified cisterns. The rubber’s durometer and elongation properties are tuned for UK ambient temperatures (5–25°C) and typical municipal water chemistry. It forms a complete seal upon tank refill and releases fully during flush activation — enabling full bowl evacuation while returning reliably to seated position. The chain length is pre-adjusted to avoid tangling or binding inside narrow tank cavities. Commonly deployed in property management portfolios, student accommodation blocks, and care home facilities — where durability, ease of stock control, and cross-model compatibility are prioritised over brand-specific OEM parts.
