What it is
The Sime 6281521 is a flange with O ring for the DAB pump, used on Sime gas boilers. It forms the sealed connection between the pump head and the manifold. The O ring sits within the flange to seal that joint against water leaks.
Signs this part needs replacing
- Water weeping or dripping at the pump head to manifold joint
- Staining, corrosion or scale on the flange face
- A flattened, hardened or perished O ring
- Falling system pressure that needs frequent topping up
Before you order
- Confirm the circulator fitted is a DAB pump
- Check your appliance model and GC number against the fitment list
- Inspect the flange face and O ring seating before reassembly
