A dry disconnect coupling (also known as a dry break coupling) is a type of quick-connect fitting that allows you to connect and disconnect fluid transfer lines without spilling or releasing hazardous substances. These are widely used in industries handling chemicals, fuels, gases, and cryogenics, where safety and environmental protection are critical.
 

🧩 Components:

1. Coupler (Female part) – Often installed on hoses or tanks.

2. Adapter (Male part) – Typically fixed to the process piping or tank inlet.

3. Internal Valves – Spring-loaded valves that open only when both parts are securely connected.
   
    

   ✅ Key Features:

4. No spill or minimal spillage
