We sell both the traditional rubber and our market leading stainless steel pigtails. Our UK made fully Stainless pigtails are very flexible but made from solid stainless which means they are not susceptible to rotting or cracking when used outside houses and catering vans on 19 or 47kg size bottles in all weathers, plus another great advantage, beside the 20 year dated life span, is they will not get damaged or eaten by Squirrels, Rats or small critters like rubber pigtails do. It's worth noting that our stainless pigtails are not to be confused with the cheaper over-braided rubber pigtail which are basically a traditional rubber pigtail with stranded stainless wire put over the rubber tube and which offer very little protection compared to the solid stainless steel versions.
