Viva Sanitary Internal Flush Cone — PP0004/A
The Viva Sanitary PP0004/A (FTB5276) is a genuine internal rubber flush cone designed to create a watertight seal between a standard toilet flush downpipe and the ceramic toilet pan inlet. Unlike external stepped sleeves that stretch over the outside of the pan socket, this internal cone inserts directly into the pan inlet spigot. Its multi-ribbed external fins compress against the internal ceramic walls, providing a secure, leak-free friction fit that prevents water escape during flushing.
Identification Guide:
MPN: PP0004/A | SKU: FTB5276 | Manufacturer: Viva Sanitary | Flush Pipe Compatibility: 1½" (38mm / 40mm OD) | Fitment Type: Internal Pan Inlet Sleeve | Material: Moulded Flexible Rubber
Key Features
- Compression Fin Design: Concentric external ribs deform and compress against the internal ceramic pan spigot for a tight hydraulic seal.
- Direct Pipe Insertion: Accepts standard 38mm (1½") outer diameter plastic flush downpipes directly into the central bore.
- Durable Rubber Construction: Flexible elastomeric rubber compound resists perishing, hardening, and water treatment chemicals over time.
- Concealed Internal Fit: Sits recessed inside the pan socket for a neat, discreet finish on modern low-level and concealed cistern installations.
Installation Note
This is an internal flush seal. Insert the cone into the ceramic pan inlet first, ensuring it sits squarely. Lubricate the inside of the cone bore and the cut end of the 1½" plastic flush pipe with a small amount of silicone grease or soapy water to allow the pipe to slide fully into place without bunching or displacing the rubber fins.
