Often used on gas cylinders, these plugs cinch and lock tightly around valve heads to block the ports—they must be cut off making it clear if the cylinder has been tampered with. The plugs are tapered to fit a range of hole diameters.

Tamper-Evident Bags

Securely transport confidential documents, money, and other materials—these bags show clear signs of tampering if they have been opened. Unlike other bags with unreliable adhesives and burdensome keys, these are sealed with locking pins or tags.
