The 36518 are versatile and portable benders. Ideal for on-site bending as well as machine construction, boiler making and industrial applications in general. The 36518 is a single circuit hydraulic system with spring return which enables the ram to be advanced in controlled stages permitting easy and precise bending of the pipes and fast withdrawal of the piston. The special safety system of the Ridgid Hydraulic Pipe Bender protects the hydraulic circuit from over-pressurisation. Supplied in a wooden case and delivered with a set of bending formers to accommodate different pipe sizes.
