Camlock couplings, also known as Cam and Groove couplings, are quick-connect fittings used to join hoses or pipes in fluid transfer applications. They are popular in industries like agriculture, chemical, petroleum, and food processing due to their ease of use and secure connection.
Camlock Coupling Types (Based on Gender & Design)
Camlock fittings are categorized by gender (Type A or Type B) and design (different styles for specific functions).
1. By Gender:
– Type A (Male/Female): The female part has grooves and accepts the male adapter.
– Example: A Type A hose coupling has a female camlock.
– Type B (Male): The male part has lugs that lock into the female coupler.
– Example: A Type B adapter has a male camlock.
2. By Design (Common Styles):
Camlock fittings come in several styles, each designated by a letter:
| Type | Name | Description |
| A | Female Coupler | Grooved receiver for the male adapter (most common hose end). |
| B | Male Adapter | Lugged plug that inserts into the female coupler. |
| C | Female Threaded | Female coupler with internal threads (e.g., NPT, BSP). |
| D | Male Threaded | Male adapter with external threads (e.g., NPT, BSP). |
| E | Female Swivel | Rotating female coupler for easier alignment. |
| F | Male Swivel | Rotating male adapter for flexible connections. |
| DP | Dust Plug | Protective cap for female couplers when not in use. |
| DC | Dust Cap | Protective cover for male adapters. |
3. By Material:
– Aluminum: Lightweight, corrosion-resistant (common for fuel, air, water).
– Stainless Steel: High corrosion resistance (food, chemical, pharmaceutical).
– Polypropylene (Plastic): Chemical resistance, lightweight (acids, solvents).
– Brass: Used in fuel and oil applications.
4. By Size:
Camlock couplings range from ½ inch to 6 inches (or larger for industrial use).
