QT Univalve Diaphragm Washers (Pack of 5) — SV32967
This bulk pack contains five genuine replacement diaphragm washers for the modern Armitage Shanks & Ideal Standard QT (Quarter-Turn) Univalve. These "New Style" washers are the official spare for the twist-lock valve body. If your current valve features an older screw-cap top, you require the Hushflow/UV washer (FTB323) instead.
Product Features
- Shaped Base: Engineered with a double-rim seal (inner and outer) specifically for QT valves.
- Quarter-Turn Fit: Exclusively for valves with the 45-degree twist-lock release mechanism.
- Genuine Quality: Direct from Ideal Standard / Armitage Shanks to ensure perfect pressure regulation.
Trade & Maintenance Pack
This 5-pack is ideal for plumbers, landlords, and maintenance professionals. Diaphragm washers are a common point of failure due to debris or chemical wear; stocking a 5-pack ensures you are always prepared to fix running toilets or slow-fill issues across multiple properties or units instantly.
How to Identify Your Valve
Before fitting, please confirm your valve type to ensure a leak-free repair:
- QT Valve: The top unlocks with a short 45° twist. (Use this SV32967 washer).
- Hushflow/UV Valve: The top is a cap that unscrews fully with multiple rotations. (Use FTB323 instead).
Note: The internal pin colour (red or white) does not affect the compatibility or performance of this genuine spare part.
