Rear white plastic part of the Poly Storm jet known as the diffuser.

The outside diameter of the diffuser is 54mm.

Helpful Sales hint :

Diffusers are an excellent purchase, not only because of the money savings but also because it does not matter what the jet is like at the front. It could be grey, white, black or stainless steel jet. The front face could be smooth, textured or scalloped. It could have a single nozzle, a twin rotational nozzle or something else. There are so many different jets BUT because you are only replacing the rear piece you have already overcome the sometimes head scratchingness difficulty of trying to find the exact jet.

We continue to be the only supplier in Europe offering ALL of the Waterway diffusers and we always have at least x500 of each type in stock. Yes we have hundreds of complete jets in stock and we are happy to help you buy these, but we also offer the most obvious "save money" alternative which is by replacing the only piece that has actually broken on the jet.

Diffusers are ONLY the rear piece of the jet - NO OTHER parts come with the diffuser. If you are missing other pieces from your jet, you will need to buy a complete jet.
