General product characteristics:

The PSR cables to be stretched are made of a flexible corrugated pipe made of corrosion-resistant steel, covered on the outside with a protective PVC material with welded / soldered ends.
PSR cables are sold in the form of a compressed corrugated tube, which allows the customer to obtain the desired length of the cable by stretching it appropriately. It is possible to increase the length of the cable up to a maximum of twice the initial (compressed) length.

Purpose and scope of application:

PSR cables to be stretched are intended for non-flexible connections (single molding) of permanently installed gas appliances with a gas installation powered by gaseous fuels specified in PN-C-04753: 2002 standards.
