The adjustable plastic seals with metal lock are made by us with flattened tail and round tail.
Using the same material, the plastic seal with flattened tail  is more resistant to traction than the seal in plastic with round tail.
The round tail plastic seal is also produced with a diameter of 1 mm and used for both water and gas meters and also for fire extinguishers.
Each of our plastic seal has a tensile strength certificate so that you can have the most complete information in choosing the plastic seal most suitable for you.
Each of our adjustable plastic seal has a chance of being realized also with PRE-CUT: is a device that offers the possibility to remove the seal without using a cutting tool.
