Viton seals

[Truckcab79]

My weedkiller pressure spray (pump up) slowly deteriorates the rubber so I normally replace them with Viton.

I’ve bought a few small pressure sprayers for hypo in the past and just buy new ones when the seals fail. I’m pretty carefully to rinse through with clean water so they last a decent time but I’d rather not be disposing of plastic if I don’t need to. Will Viton seals withstand hypo or is there something else?

Viton seals should resist Hypo no problem.

Brilliant. Thought they should. Only reason I doubted it as that when I’ve looked at chemical resistant sprayers they’re silly money in comparison. Thought it must be too easy that you can just change the seals in a cheap one.
Many thanks.
