Best way to store diaphragms?

I've got a set of vacuum slides that have been shimmed and had the needles changed according to the stage 3 jet kit for the 1150. I don't want to put them in now, but that doesn't mean I won't in the future.

In the meantime, what's the best way to store them so they don't rot out or worse? Coat them in something? Just leave them in the spare rack I've got? Ziplock bags?
 
My vote is to clean them with soap and water, dry off, stick in plastic bag, stick bag in box, stick box in cool dry place.
 
Not sure if it's the same, some neoprene ski boot liners said it was ozone that made them deteriorate, so an airtight bag would be a good start. I like Nessism's idea, I would also turn the diaphragms down evenly so they don't get crinkled anywhere, like they do when laid on their sides..
 
Ask your girlfriend how she keeps her diaphragm form drying out, lol
 
OK, this is from a plastics engineer I used to work with, find a pure silicone, coat them heavily and store them soaked in the silicone. The guy said anything rubber will last forever as long as it is soaked and coated.
 
I'd spray them with a silicone lubricant and do what Ed said.
I'd also be happy to store them in my carbs.
 
Coat them in silicon, stick them in the carb rack the seal the whole lot in a bag... or like me, just chuck the rack up on the shelf....

Dan :)
 
Silicone sounds risky to me; we don't know what the slide diapharams are made out of and the oils may attack the rubber. No risk my way.:)

I was a rubber chemist for a few years. keep the silicone away from them. There are many kinds of silicones, with many kinds of additives, and you have no way of knowing what is in them. They were designed to work in gasoline.

Store them clean and dry in a zip-lock bag, surrounded separated by some stiff cardboard. The cardboard with keep them from being folded other things near them get moved. That will be your real danger, things that might fold or puncture them.

And, as expensive as they are, label them well.

I think that if I had a set of them, I'd stick them in a folder in a file cabinet.
 
Factory packing for new slides...:)

I've used silicone spray for many years and it really helps rubber parts stay in good condition. On my bikes and cars, including under the cars. As said earlier, there are different types of silicone. I admit I never researched them all but the stuff I use from work seems to help any rubber part I apply it to. I even use it on my wiper blades and it doubles their normal life if not more.
I've applied it to various carb rubber parts I've stored for years and they always look good when I need them. Never stored diaphragms though. I imagine storing them flat in a baggie in a cool place would be good enough if you're worried at all about spraying some silicone on them.

Bought them off ebay for something like $15 each. Only have two new ones though (for BS32's) but have a four good uses ones from a set of 34's.
 
I work for a company that makes commersial aviation parts, and we use tons of O-rings and rubber gaskets. We won't stock anything without the "cure date" due to shelf life concerns. These parts typically come in sealed plastic bags for the most part and the rubber is dry, no goop of any sort on the outside.
 
Either way (silicone or not) if they're sealed up kept in the dark and cool...they'll last longer than most members on this fourm. :eek: :p

I use silicone on all EPDM, Rubber, Plastics, and even on the glove box door of the 'Bird (when a freon can with seal conditioner exploded inside the car) :mad: and have VERY good luck. You'de be amazed what can be done to 25+ year old weather stripping, it is new again. Also Meguiars have a rubber/vinyl treatment in the Mirror Glaze line http://www.autogeek.net/meguiars-car-care-products.html
that will do wonders with oxidized felxible ruber/plastic parts. Been using it for years and am VERY impressed. All you need is a little elbow grease...
