Foodsaver 2400 gasket

SOURCE: Foodsaver V2440 won't vacuum air out

If your FoodSaver is more than a couple years old, the gaskets have probably gotten compressed. Especially if you use it often or store it with the lid in "latched" position.
FoodSaver's website has replacement gaskets, $3 each, but it's hard to match the right gasket with the V2440. I called and got confirmation: it's this one. http://www.foodsaver.com/Product.aspx?id=r&cid=0&pid=294
Same gasket, upper and lower, even though it's listed as "Upper" on the Web page. You can also call them at 877-777-8042 and order Part # T910-00075.
Meanwhile, I've had good luck with soaking the old gaskets in warm water for a few minutes, then letting them air-dry. It seems to restore their sealing power for a day or two at most, but that's enough for me to vac up my weekly freezer groceries.

This is likely happening because the unit cannot detect that a vacuum has formed, and the gaskets around the vacuum channel are the probable culprit. The Foodsaver gaskets will deform and/or dry out with time, just like in any device, but you don't necessarily have to replace them. I've tried this inexpensive solution on my own Foodsaver V2490, and it works perfectly.
Buy some food-grade silicone grease and apply it to both the upper and lower gaskets. I remove the gaskets and coat both sides with a thin layer of grease before replacing them in their respective channels. And since this grease will be absorbed and/or dry out with time, you will have to do this occasionally, so I also flip the gaskets (i.e. turn them over) whenever I apply the grease.
You can buy a 2 oz container of silicone grease at any dive store, or you can buy it over the Internet by searching for "Trident silicone grease".

I do not work at this dive center, but I am a scuba diver and already had some grease that I use for the numerous rubber gaskets in my gear. The 2 oz. jar will last you several years, and you will find many other uses for it around the house since the grease will last longer than a spray.

This is likely happening because the unit cannot detect that a vacuum has formed, and as a result, the unit never "turns on" the heating element to seal the bag, with the gaskets around the vacuum channel being the probable culprit.
