PGS is a locking device for pipes made of polycarbonate or polypropylene. It is designed to seal cap nuts to prevent their twisting and disconnection of pipes, as well as the removal of gas meters and installation of bridge cables for bypass devices for the purpose of stealing gas. 

The pipe locking device consists of two semicircular-shaped parts with additional holes for the sealing rope. To install the pipe locking device, it is necessary to connect both parts on the mounting nut, put the sealing rope into the special holes on the sides of PGS, and install the seal (rotary or latch one). The seal should be placed as close as possible to the locking device. The tamper-evident seal and rope will prevent intruders from keeping the fact of removal of the seal and the locking device from the nut unnoticed.

When an attempt is made to perform certain actions with the aim to steal gas or water, visible signs appear on the seal, which is evidence of an attempt of external interference and, in fact, tampering.
