5-Pack: Dudley Hydroflo Cistern Inlet Valve Diaphragm Washers — Revised Blue
This 5-piece Bulk Pack of Genuine Dudley Diaphragm Washers is the ultimate maintenance solution for properties using Hydroflo or Aquasave inlet valves. Diaphragms are the primary wear-and-tear component in any cistern; having a multi-pack ensures you can instantly resolve leaks, "whistling" valves, or slow-fill issues across multiple toilets. These units feature the latest blue-insert design for maximum reliability and a superior seal.
