Most types of (valve) car seals are self locking. They
operate in just the same way as a cable tie wrap. After threading the cable of
the car seal around the valve wheel or lever and the valve body, then the cable
end is passed into the head of the seal it locks straight away. You cannot pull
the cable back out again. The only way to remove it is to cut the cable.
However, there is a different type of seal available called
the breakaway car seal. These seals have a locking key. With the cable end
passed in to the seal head, it can still be slid out again. To lock the cable
in place it is necessary to tighten the locking key until the handle breaks
off. Once the key handle snaps off, the cable cannot be removed. As with the
self-locking seal, it’s necessary to cut the cable to remove the seal.
Some people mistakenly believe this type of breakaway car
seal is re-useable. This is not the case. But this type of seal can be
temporarily deployed by lightly turning the key handle until it grips the
cable.
Remember, the purpose of the car seal is to seal the valve
in the open or closed position. If the seal is removable, then it’s not fulfilling
its function.
