The C160 is designed primarily for sealing fire extinguishers after annual testing, which is why it has a very low break strength, to allow easy removal in the case of emergency.

Most seals are supplied plain, as the colour identifies the year the fire extinguisher was tested - this is usually changed at every annual check up.

The C160 can be printed with name / logo and serial number if the customer requires every seal to be accounted for.
