Thanks to the resistant GEROfit® protective jacket made of modified polypropylene, the damage caused by mechanical loads can be largely avoided. This in turn has a positive effect on an optimum cost-benefit ratio in pipe laying.

An extensive range of accessories (smooth-ended/­socked parts, weld fittings, flanges, tools, machines) rounds off our delivery range.
