Hello. I am trying to find a food grade spigot that doesn’t have silicone and EPDM gaskets inside. I suppose the outer gaskets can be replaced, but the O-rings can be a pain. I tried searching the web and nothing came up. So, is there a spigot that uses natural rubber or any other biodegradable material for its gaskets? Thank you in advance for any response and sorry if I posted this in the wrong “sub-lemmy”.
Or it’s not really worth it financially, I suppose. I mean, my initial idea was to find an all-metal pump dispenser. There are none and I think they would be both safe and legal?
My guess is if they made one without the gaskets, it would leak.
I have been trying to get my hands on some pump dispensers from like 100 years ago. I am curious how they used to be made then. Obviously no plastic, but perhaps rubber was most likely used.
I know they had a leather flap that worked as the pump check valve… likely the same for gaskgets. It would have been tanned but not treated (rawhide?)
I’ll obviously never use leather for any future products. I did have graphite in mind, but it’s still on the drawing board (another project). Right now I think I will have to give up and rely on the food-grade spigots that are available on the market. I would honestly make them myself from scratch but the investment required is astronomical for me right now. Maybe in the future.
