Is the Plug connector reduction, type R8 compatible with oil-based fluids or only air and vacuum?

Based on the provided description, the Plug connector reduction, type R8 is specified for vacuum and air as the working media. Materials and seals: nickel-plated brass body with NBR (nitrile) sealing. NBR is resistant to many oils and fuels but has limitations (reduced resistance to aromatic hydrocarbons, some hydraulic fluids, and high temperatures). The productâs rated working medium and temperature range (â20Â°C to +80Â°C) indicate the manufacturer intended it for pneumatic/vacuum use; oil-based fluids are not listed as approved media. Therefore you should treat Plug connector reduction, type R8 as compatible only with air and vacuum unless you obtain explicit confirmation from the manufacturer that a specific oil or hydraulic fluid is acceptable given the NBR seal and operating conditions.

Can Plug connector reduction, type R8 be used with temperatures outside the -20Â°C to +80Â°C range?

No. Plug connector reduction, type R8 Format is specified for an operating temperature range of -20Â°C to +80Â°C. Using it outside this range may compromise the NBR sealing, nickel-plated brass housing, mechanical integrity and pneumatic performance (leaks, loss of sealing, material degradation). If application temperatures will be lower or higher, choose a connector rated for that range or confirm with the manufacturer for alternative materials/seals compatible with the required temperatures.

Can Plug connector reduction, type R8 be used with gases other than air and vacuum (e.g., inert or corrosive gases)?

Plug connector reduction, type R8 is specified for vacuum and air only. Its construction materials and seals (nickel-plated brass body, NBR sealing) and stated operating limits (working pressure up to 16 bar, temperature -20Â°C to +80Â°C) determine compatibility: - Inert gases (e.g., nitrogen, argon): Often compatible in many practical situations, but not guaranteed. NBR seals can handle many inert gases at stated temperature/pressure, and nickel-plated brass is generally resistant. However, confirm with the gas supplier or perform compatibility checks for your specific conditions (purity, pressure, temperature, flow, and any contaminants). - Corrosive or reactive gases (e.g., chlorine, hydrogen sulfide, ammonia, fluorinated gases): Not recommended. Corrosive gases can attack NBR and brass or the nickel plating, leading to seal failure, leaks or material degradation. Even small concentrations of acidic or halogenated gases can cause rapid damage. - Oxygen or high-purity/process gases: Not advised without verification. NBR is not ideal for high-purity oxygen service due to flammability risks and possible degradation; special materials and cleaning are typically required. Recommendation: Do not assume safe use with gases other than those specified. For any non-air/vacuum medium, consult the manufacturer for gas compatibility, request material certificates, or select connectors with seals and body materials qualified for the specific gas (e.g., Viton/FKM, EPDM, PTFE seals; stainless steel bodies) and for the required pressure/temperature and safety standards.
