Is the Free-flowing quick-connection plug with GZ BSP, stainless steel, series 25 DN 7.8 suitable for use with aggressive liquids and gases at 35 bar?

Free-flowing quick-connection plug with GZ BSP, stainless steel, series 25 DN 7.8: Based on the provided description, this plug is rated to a working pressure of 35 bar and is made from AISI 316Ti and AISI 303 stainless steels. AISI 316Ti offers good general corrosion resistance and is often suitable for many aggressive liquids and gases (chlorides, acids, seawater) better than 303. However, suitability for a specific aggressive fluid or gas at 35 bar depends on chemical compatibility, temperature, presence of halides, oxygen, and additives. Conclusion: - Pressure: yes . rated for 35 bar. - General chemical resistance: likely acceptable for many aggressive media thanks to AISI 316Ti, but AISI 303 is less corrosion-resistant and may be a weak point. - Recommendation: verify compatibility with the exact fluid/gas, concentration, temperature, and exposure time; consult material chemical resistance charts or supplier/manufacturer for approval at 35 bar. If media is highly corrosive (strong acids, chlorides at elevated temp, H2S, etc.), consider all-316L/316Ti design or special alloys.

Can the Free-flowing quick-connection plug with GZ BSP, stainless steel, series 25 DN 7.8 be used for compressed air at flow rates up to 1800 l/min?

Yes. The Free-flowing quick-connection plug with GZ BSP, stainless steel, series 25 DN 7.8 is specified for compressed air with a performance of 1800 l/min at Pe = 6 bar and Îp = 0.5 bar, and a working pressure up to 35 bar. Materials AISI 316Ti and AISI 303 stainless steel are suitable for typical compressed-air applications. Therefore it can be used for compressed air at flow rates up to 1800 l/min, provided operating conditions do not exceed the stated pressure and Îp limits.

Does the Free-flowing quick-connection plug with GZ BSP, stainless steel, series 25 DN 7.8 require special maintenance for liquids and gases?

No special maintenance is required specifically because the Free-flowing quick-connection plug with GZ BSP, stainless steel, series 25 DN 7.8 is designed for use with compressed air, liquids and gases and is made from corrosion-resistant AISI 316Ti and AISI 303 stainless steels. Standard maintenance best practices should be followed: - Regular visual inspections for damage, wear, corrosion or contamination. - Clean sealing surfaces and threads with compatible, non-aggressive cleaners to prevent debris buildup. - Lubricate moving seals or Oârings only with lubricants compatible with the conveyed media and seal materials. - Replace worn or damaged seals, Oârings and components promptly to maintain leak-free performance. - For aggressive or hygienic media, follow specific cleaning, sterilization or material-compatibility procedures recommended for those fluids/gases. - Adhere to rated limits: operating pressure up to 35 bar, typical performance shown for air (1800 l/min at Pe=6 bar, Îp=0.5 bar); avoid exceeding these limits. If the application involves toxic, reactive, food, pharmaceutical or sterile media, consult material-compatibility and industry-specific maintenance procedures and consider more frequent inspections, cleaning protocols and traceability.
