FAQs
Is this the same as the diaphragm?
No. This is the outlet/base seal at the cistern outlet. The upper diaphragm sits inside the valve body and is a different part.
Does it include any bolts or fixings?
No — this listing is for the seal only. Reuse your existing fixings or purchase separately as required.
Will it fit the Storm 22A?
This specific seal is listed for Storm 33A and Skipper 45. For other SIAMP models, select the matching outlet/base seal.
