- Long out of production for the Fiat 1100/103 water pump. Reverse-engineered and produced by Replique labs as a complete assembly - available on request, including small batches.
Reference 841769 is a water pump seal (premistoppa) for the Fiat 1100/103, long out of production. It is a full mechanical shaft seal assembly - brass upper ring, lower ring and body, a carbon slip ring, a rubber bellows and a stainless-steel spring - not a simple gasket. When it perishes, the water pump leaks. Replique labs reverse-engineers the seal from an original, machines the brass elements, casts the flexible components and assembles a verified, ready-to-fit unit. Available as a single piece or a small batch, with the design kept on file for repeat orders.

Will it survive heat near the engine?
We select temperature-rated materials for under-bonnet locations and say clearly what the chosen material tolerates.
Will the colour and finish match my interior?
We match sheen and texture as closely as the process allows, and confirm finish options in the quote.
Do you supply the CAD files?
File ownership is agreed per project - tell us in the RFQ if you need the model as a deliverable.

Yes, with your consent - reorders then skip straight to production.
