Can the 90Â° angle plug connector, type R4 maintain a reliable seal at 16 bar and temperatures from -20Â°C to +80Â°C?

Yes. The 90Â° angle plug connector, type R4 is specified for a working pressure of 16 bar and an operating temperature range of -20Â°C to +80Â°C. It uses NBR (nitrile) sealing and is made of nickelâplated brass, designed for pneumatic media (vacuum, air) and repeated assemblies without loss of mechanical or pneumatic sealing. Under these stated conditions.16 bar and -20Â°C to +80Â°C.the connector should maintain a reliable seal, provided installation is correct, the media is compatible with NBR, and the seal and mating surfaces are undamaged and properly assembled.

Is the 90Â° angle plug connector, type R4 suitable for use with vacuum and compressed air systems?

Yes. The 90Â° angle plug connector, type R4 is suitable for use with vacuum and compressed air systems. It is specified for vacuum and air as the working medium, supports a working pressure up to 16 bar, and provides reliable sealing with NBR. Constructed from nickel-plated brass and rated for temperatures from â20Â°C to +80Â°C, it is designed for multiple assemblies without loss of mechanical or pneumatic sealing.

Does the 90Â° angle plug connector, type R4 use NBR seals compatible with oil-contaminated compressed air?

Yes. The 90Â° angle plug connector, type R4 uses NBR (nitrile rubber) sealing. NBR is commonly resistant to mineral oils, lubrication oils and many hydrocarbon-based contaminants found in oil-contaminated compressed air systems, and performs well across the connectorâs specified temperature range (-20Â°C to +80Â°C) and up to 16 bar. However, compatibility depends on the specific type and concentration of oil or chemical contaminants present. NBR is less resistant to certain synthetic oils, ester-based fluids, some solvents, ketones and ozone/oxidizing agents. For continuous exposure to aggressive or unknown oils, or where long-term chemical resistance is critical, consider verifying the exact oil formulation against NBR chemical compatibility charts or choosing a fluorocarbon (FKM/Viton) or other specialty elastomer with better resistance. Summary: NBR seals in the 90Â° angle plug connector, type R4 are generally compatible with typical oil-contaminated compressed air (mineral/lubrication oils), but confirm against the specific oil chemistry and exposure conditions for reliable long-term performance.
