GPDO: Maximum performance in a compact format

GPDO-80: Our igh-performance stainless steel quick coupling

At IMOPAC, we know that every connection matters. That’s why we’ve developed the GPDO-80, a double shut-off quick coupling made from AISI 316 stainless steel, ideal for demanding industrial applications.

The GPDO-80 reflects our commitment to excellence, offering technical solutions that truly make a difference in the day-to-day operations of our clients. To date, it is our highest-performing double shut-off quick coupling.

Design and technical specifications

The GPDO-80 is made of AISI 316 stainless steel, ensuring long-lasting performance in complex industrial environments. Equipped with FKM seals, it can operate in a temperature range of –20 °C to +205 °C, making it a reliable option even under extreme conditions.

With a recommended working pressure between 0 and 12 bar, this quick coupling delivers consistent and dependable performance. In addition, its design allows for a flow rate of approximately 520 l/min, according to tests on our in-house bench—ideal for applications where airflow or water flow is critical.

Key features of the GPDO-80

1️⃣ Double shut-off and mechanical opening: Ensures safe connection and controlled disconnection, reducing drips and fluid loss.
2️⃣ Vacuum compatible: Offers flexibility for applications that require this feature.
3️⃣ Bidirectional flow: Allows circulation in both directions, expanding its range of uses.
4️⃣ Anti-drip design: Minimizes leakage during disconnection—ideal for working with air and water.

Durability and industrial applications

The GPDO-80 is engineered to withstand harsh environments, thanks to its robust construction and high-quality materials. Its ability to work with both air and water makes it an ideal choice for sectors such as:

  • Laboratories and chemical processing: Wide temperature range and fluid compatibility.
  • Water treatment: Corrosion resistance and anti-drip design.
  • Industrial automation: Quick and secure connections for controlled processes

Industrial use cases

The GPDO-80 is designed for demanding environments where performance and reliability are a must:

  • Water treatment: Perfect for minimizing fluid loss and ensuring safety in distribution systems.
  • Industrial automation: Optimal for fast, secure connections in complex systems.
  • Laboratories: Built to handle extreme temperatures and guarantee precision in chemical applications.

Flexibility and adaptability

We’ve developed a coupling designed for specific pneumatic applications. However, as manufacturers, we understand that each industrial sector has unique challenges and requirements. That’s why the GPDO-80 is fully customizable based on the client’s or application’s specific needs. If you need adjustments to the coupling design, sealing materials, or construction, our technical team is ready to develop a tailored solution¹.
