Is the Connection with extended spigot with male thread, type R18 compatible with oils or only with air and vacuum?

Connection with extended spigot with male thread, type R18 is specified for pneumatic use: working medium listed as vacuum and air. Materials and seals . nickel-plated brass body with NBR (nitrile) sealing . technically allow contact with many oils and greases, but the product description and rated working medium do not certify it for oil service. NBR offers good resistance to mineral oils but is less compatible with some synthetic oils, hot oils, or aggressive fluids; the 16 bar rating and temperature range (â20Â°C to +80Â°C) are for pneumatic applications as specified. Conclusion: Use Connection with extended spigot with male thread, type R18 for air and vacuum as intended. If you plan to use oils, verify compatibility case-by-case: check the specific oil type, temperature, pressure and consult the manufacturer for approval or choose fittings and seal materials explicitly rated for oil service.

Can the Connection with extended spigot with male thread, type R18 be used with food-grade gases or in food processing environments?

Connection with extended spigot with male thread, type R18 is specified for vacuum and air, with sealing made of NBR and body of nickel-plated brass. It is not certified or described for use with foodâgrade gases or direct contact in food processing environments. NBR seals and nickelâplated brass may not meet foodâcontact regulations (e.g. FDA, EC 1935/2004) and can absorb oils or degrade with certain food gases/cleaning agents. For food applications, use fittings explicitly certified for food contact and compatible seal materials (e.g. FDAâapproved elastomers, EPDM or FKM per regulations) and verify material declarations and certifications from the manufacturer.

Can the Connection with extended spigot with male thread, type R18 be used with corrosive gases or aggressive chemicals?

Connection with extended spigot with male thread, type R18 is specified for use with vacuum and air, made of nickel-plated brass with NBR sealing, working pressure up to 16 bar and temperature range â20 Â°C to +80 Â°C. Based on this description, it is not recommended for use with corrosive gases or aggressive chemicals. Reasons: - Nickel-plated brass can corrode or suffer dezincification when exposed to many aggressive media (strong acids, alkalies, halogenated compounds, ammonia, hydrogen sulfide, chlorides, etc.), compromising mechanical integrity and sealing. - NBR (nitrile rubber) has limited chemical resistance: it performs well with oils, air and some nonâaggressive hydrocarbons but degrades with many solvents, ketones, chlorinated hydrocarbons, acids, and oxidizing agents. - The productâs stated working medium (vacuum, air) implies it was not tested or rated for corrosive or aggressive chemical service. If you need use with corrosive gases or aggressive chemicals, choose materials and seals rated for those media (e.g., stainless steels, specialty alloys, PTFE or FKM/EPDM seals as appropriate) and verify chemical compatibility and certification from the manufacturer. For safety, consult the manufacturerâs chemical compatibility data or technical support before using Connection with extended spigot with male thread, type R18 with any corrosive or aggressive substances.
