What is the significance of the G 1/4 female thread in this coupling?


The G 1/4 female thread allows for compatibility with various threaded connection fittings, ensuring secure and reliable coupling with standard hoses and tools commonly used in pneumatic systems.

How does the nickel plating impact the performance of this coupling?


Nickel plating enhances the coupling's corrosion resistance, making it suitable for environments with exposure to moisture and other corrosive elements, thereby extending its lifespan.

What pressure range can this coupling handle in different temperature conditions?


It can operate from -0.095 MPa (approximately -0.95 bar) to 1.2 MPa (up to 12 bar), ensuring reliable performance across a broad range of temperatures and applications.

Is lubricated operation necessary for this coupling to function effectively?


While lubricated operation is possible and can improve efficiency, the coupling is also designed to perform effectively without lubrication, depending on the specific application requirements.
