Is the Adjustable angle plug connector with male thread, type R31 compatible with standard pneumatic fittings and multiple assembly cycles without seal loss?

Yes. The Adjustable angle plug connector with male thread, type R31 is compatible with standard pneumatic fittings and is designed for repeated assembly cycles without seal loss. Its nickel-plated brass construction, NBR sealing and working pressure rating of 16 bar make it suitable for vacuum and air media across -20Â°C to +80Â°C. The product description specifically states it is easy and quick to use for multiple assemblies without loss of sealing on both mechanical and pneumatic sides, confirming reliable compatibility and reusability.

How does the Adjustable angle plug connector with male thread, type R31 maintain sealing after repeated assemblies under 16 bar?

Adjustable angle plug connector with male thread, type R31 maintains sealing after repeated assemblies under 16 bar through its durable construction and reliable sealing materials. The nickel-plated brass body resists wear and deformation during multiple connects/disconnects, preserving precise mating surfaces. The sealing element is made of NBR, a resilient elastomer that sustains elasticity and conforms to the mating faces to keep both mechanical and pneumatic seals tight. The design is optimized for easy, quick multiple assemblies, ensuring consistent compression of the NBR seal and secure thread engagement so that, within the specified working pressure (up to 16 bar) and temperature range (â20Â°C to +80Â°C), leakage is prevented even after repeated use.

Can the Adjustable angle plug connector with male thread, type R31 be safely used with vacuum systems and compressed air up to 16 bar?

Yes. The Adjustable angle plug connector with male thread, type R31 can be safely used with vacuum systems and compressed air up to 16 bar. Its specifications explicitly list the working medium as vacuum and air and the working pressure as 16 bar. The connector is made of nickel-plated brass, uses NBR sealing, and is rated for operation from -20Â°C to +80Â°C, so ensure your system conditions (pressure, temperature, and medium compatibility with NBR and brass) fall within these limits. Also verify installation and maintenance practices to maintain sealing integrity over repeated assemblies.
