What it is
The Sime 2030225 is a small sealing gasket measuring 5.5mm x 11mm x 2mm, listed by the manufacturer as a washer gasket Ø 5.5 x 11 x 2, 1/4. It is fitted to seal joints on Sime gas boilers across the Avant, Brava, Climit, EDEA, Format, Murelle and Metro ranges. It forms the compression seal at the joint it serves, preventing leakage at that connection.
Signs this part needs replacing
- Water or gas weeping at the joint the gasket seals
- Visible flattening, hardening or cracking of the gasket
- Scale or corrosion deposits around the sealing face
- Damp staining or residue beneath the joint
- Repeated pressure loss traced back to the joint
Before you order
- Confirm your boiler model and serial number against the manufacturer's parts list
- Measure the old gasket to confirm 5.5mm x 11mm x 2mm
- Check how many gaskets the joint requires before ordering
- Gas-carrying joints must be reassembled and tested by a competent person
