Waterproof sensor plug

Can anyone recommend a cheap waterproof "plug" to use for wiring an external sensor to a case-enclosed arduino?

I'm planning an outdoor application where the arduino sits in a waterproof case, exposed to the elements, with up to 12 4-pin analog sensors individually extending from the case. The arduino will be wired to 12 female plugs on the inside of the case, and the actual sensor/cable will connect via a male plug on the outside of the case. Not all sensor plugs will be used, so I need to plug to be waterproof even if nothing's plugged into it.

Googling finds tons of plugs, but most are $20-30 a piece and designed for high-end industrial applications. Where would I find something cheaper, geared more towards a consumer application?

That's probably because it's all wet. You forgot the tarp. lol

use some chewing gum to fill your holes. or cover the whole thing with spray on foam insulation and paint it to look like a rock. this is my junction box. i even stuck moss on it. i cut out a cupholder in the top corner. someone i know said "why is their a big cement block over there?" i said its a rock. it fooled him...lol
