Is the Swivel coupling for pneumatic hoses with external thread and protective spring suitable for use with soft plastic hoses at 18 bar working pressure?

Yes. The Swivel coupling for pneumatic hoses with external thread and protective spring Format is suitable for soft plastic hoses at a working pressure of 18 bar. Its description explicitly states compatibility with hoses made of soft plastics and lists the working pressure as 18 bar. The nickel-plated brass construction and protective spring help ensure durability and strain relief at that pressure, but ensure hose inner diameter and thread size match the coupling specifications and follow proper assembly and safety practices.

Does the Swivel coupling for pneumatic hoses with external thread and protective spring resist corrosion in wet environments at 18 bar?

Swivel coupling for pneumatic hoses with external thread and protective spring Format is made of nickel-plated brass and rated for a working pressure of 18 bar. Nickel plating improves corrosion resistance compared with unplated brass, and brass itself offers good resistance to water and many wet environments. However, resistance to corrosion in wet environments depends on factors beyond base material and plating: - Continuous immersion or saltwater exposure accelerates corrosion; nickel-plated brass is less durable in marine or highly corrosive (chloride-rich) environments than stainless steel or higher-grade coatings. - Mechanical wear, abrasion, or damage to the nickel plating (common at the swivel interface and spring contact points) can expose underlying brass and create galvanic cells, increasing corrosion risk. - The protective spring (material unspecified) is critical: if the spring is steel and not stainless or otherwise coated, it may corrode faster than the nickel-plated brass body. - Operational conditions such as temperature, presence of chemicals, turbulence, or frequent flexing of soft-plastic hoses can also affect long-term corrosion behavior. Conclusion: Swivel coupling for pneumatic hoses with external thread and protective spring Format offers reasonable corrosion resistance in typical wet, non-aggressive environments at 18 bar, but it is not guaranteed to resist corrosion in highly corrosive, marine, or continuously immersed conditionsâespecially if the spring is not stainless or if the nickel plating is damaged. For harsh or marine wet environments, consider stainless-steel variants or confirmed corrosion-resistant springs/coatings.
