The parts are all fine -however, it would have been helpful, if there was at least a diagram of which seals and o-rings go in which location. No instructions were supplied.
It seems that not all the provided seals and o-rings are used in the model of back pack sprayer we have (Swissmex 503). There were several left over without a 'home', and I am not sure if they were left over because they were for a different model, or if they should have been used in this sprayer. If they should have been used for this model, then it was not apparent where they should be installed. An exploded diagram would have been useful.
