Conductive gaskets are built with conductive fabric placed over flexible foam. They have an adhesive backing (a small strip pulls off like a sticker). They can be used to seal ad-hoc Faraday cages, including metal garbage cans, gun safes, and ammo cans. The important point when buying a gasket is to ensure that it fits. You want it to create a conductive seal along the inside of a gap or joint. That means that the ideal physical geometry of the gasket depends on what you’re trying to seal.
Please see the FAQs section to learn more about how gaskets work and how they are used.
Sealing Galvanized Garbage Can
Image showing two 0.23″ gaskets spliced on the inside sidewall of the lid.
Galvanized Garbage Can Gaskets – seen in video and photo above
Two gaskets, 0.23″ (W) x 39.37″ (L) x 0.079″ (T). These are the thin gaskets I used in the trash can video.
Sealing Large Ammo Can
Large Ammo Can Gaskets – seen in video above
Two gaskets, 0.67″ (W) x 39.37″ (L) x 0.279″ (T). These are the thick gaskets I used in the ammo can video.
Sealing Small Ammo Can
Small Ammo Can Gasket – seen in photo above
One gasket, 0.2″ (W) x 39.37″ (L) x 0.16″ (T). One gasket is enough for small ammo can.
Gun Safe Gaskets

I used 4, 0.39″ (W) x 39.37″ (L) x 0.11″ (T) for the demonstration in the video. For reference, the door on the gun safe in the demonstration is 24” wide and around 54” tall.
