Coilhose Pneumatics manufactures Nylon Coils from tough, abrasion resistant Nylon material. Nylon offers a large temperature range of -60F to +200F, and a higher working pressure. The stiffness of Nylon also creates a high retraction force, allowing for the coils to store quickly out of the workspace. Coilhose Pneumatics' Nylon Coils are equipped with strong brass fittings that are machined in-house out of quality brass hex stock. Assemblies are equipped with a spring guard to prevent kinking at the fitting.
