Yes I have worked with PEEK before, quite high temperature resistance. I could be wrong but the plastic they used looks a lot like PTFE, commonly known as Teflon (the pan coating) which itself has quite high temperature resistance. Definitely higher than Acetal commonly used for centre post insulators on drippers.
I have enquired about getting a replacement batch in.
Hi @JakesSA,
Any word on these? I can't use my Subtank any more, the insulator taste is horrible as the deck heats up.
Cheers,
