Parker manufactures one of the largest selections of convoluted tubing. Product offerings include MIL Spec Convoluted Tubing for electrical conduit (81914), Wire Wrapped Convoluted Tubing to achieve a tighter bend radius, Low Profile Convoluted with a larger inside diameter for increased flow and a Heavy Wall Convoluted that is produced with a thicker wall to reinforce the strength of the tube. The added material in heavy wall convoluted withstands flanging and flaring, allowing the tubing to actually pass through the inside of the fitting so it can be flared over the face of the fitting. This eliminates the problem of bacterial entrapment and adds the benefit of unrestricted flow by providing 100% PTFE coverage on all wetted surfaces.

Convoluted tubing's helical constructions are molded into the tubing and will not pull out as the tube is extended. Like other fluoropolymers, Parker convoluted tubing resist corrosive liquids and gases, and has a non-stick surface with low permeability. All of these products can be manufactured with a conductive I.D. or as a fully conductive tube to dissipate static build-up and they are available as bulk tubing or as a cut tube with added cuffs to create an attachable end for adding fittings or flanges.
