Hosco has a unique hose that provides significant ergonomic improvement of flexibility and weight reduction versus the nylon hose or tubing equivalent size. In addition, there is benefit to increasing the dielectric strength with the multiple layer construction versus solid core nylon hose or tubing. The CPH series of hose is available in 1/4”, 5/16” and 3/8” ID sizes and is dimensionally equivalent to our NP-4 (6.35mm), NP-5, (8mm) or NP-6 (9.7mm) solid core nylon hose using the same family of connectors. The CPH has a thin sheath of PA-Nylon on the inside lining and outside cover to provide resistance to solvent or chemical attack like solid core PA-Nylon, but its core tube is PUR-PolyUrethane to provide the increase in flexibility and reduction in weight. The multi-layer construction seems to provide additional dielectric strength when compared to PA-Nylon but not to the dielectric strength of FEP, PTFE or UHPPFA Flouropolymers performance level.
