Is the Straight through plug connector, type R3 compatible with both vacuum and compressed air applications up to 16 bar?

Yes. The Straight through plug connector, type R3 is specified for a working pressure up to 16 bar and lists the working media as vacuum and air, so it is compatible with both vacuum and compressed air applications within those limits. Construction details supporting this compatibility include nickel-plated brass material, NBR sealing, and an operating temperature range of â20Â°C to +80Â°C. Ensure your system pressure does not exceed 16 bar and that temperature and chemical compatibility with NBR are acceptable for your specific application.

Can Straight through plug connector, type R3 be used in outdoor environments within its â20Â°C to +80Â°C operating temperature range?

Yes - Straight through plug connector, type R3 Format can be used outdoors within its specified operating temperature range of â20Â°C to +80Â°C. Its materials and specifications (nickel-plated brass body, NBR sealing, rated for vacuum/air and 16 bar) support use in that temperature window. However, outdoor conditions may introduce additional factors not covered by the temperature rating alone - e.g., prolonged UV exposure, salt spray/corrosion in marine environments, extreme thermal cycling, or direct immersion - which could affect nickel plating or NBR seal longevity. For critical or harsh outdoor exposures, consider protective measures or verify suitability with the manufacturer.

Does Straight through plug connector, type R3 maintain seal integrity after repeated disconnections and reconnections?

Yes. The Straight through plug connector, type R3 is designed for repeated disconnections and reconnections without loss of sealing on both the mechanical and pneumatic sides. Its construction from nickel-plated brass and NBR sealing material, combined with suitability for vacuum and air at working pressures up to 16 bar and temperatures from -20Â°C to +80Â°C, supports durable seal integrity across multiple assemblies.
