Camlock Coupling Type D
Camlock Coupling Type D is characterized by its female coupler with cam arms and female threaded end, making it suitable for a wide range of industrial applications where a secure and efficient connection between a hose and a female-threaded pipe or fitting is needed. The female coupler has cam arms that lock onto a male adapter (such as Type A, E, F, or another compatible type), securing the connection. The female threaded end allows it to be screwed onto a male-threaded fitting, pipe, or valve.
- Type D Couplers are generally used with the same size Type A adapters.
- However, they are also compatible with the same size Type E and Type F adapters.
- They can be sealed and closed off with the same size Type DP (Dust Plug).
Camlock Standards
Camlock couplings, also known as cam and groove couplings, are standardized under several international and national standards. The primary standards include:
- MIL-C-27487: This is the original military specification developed in the United States, which many commercial camlock couplings are designed to meet.
- EN 14420-7 (formerly DIN 2828): This European standard specifies the dimensions, materials, and performance requirements for cam and groove couplings. It ensures compatibility and interchangeability among manufacturers in Europe.
- A-A-59326: This is a commercial item description (CID) published by the General Services Administration (GSA) in the United States, which has replaced the MIL-C-27487 standard for new designs and procurements. It maintains the requirements for dimensions, materials, and performance similar to MIL-C-27487.
These standards ensure that camlock couplings from different manufacturers can be used interchangeably and meet certain safety and performance criteria. They cover various aspects such as material types (e.g., aluminum, brass, stainless steel, and polypropylene), pressure ratings, and dimensional tolerances.
Description of Camlock Coupling Type D
- Components: Type D consists of a female coupler with cam arms and a female thread. The female coupler has cam arms that lock onto a male adapter (such as Type A, E, F, or another compatible type), securing the connection.
- Connection: The female threaded end allows it to be screwed onto a male-threaded fitting, pipe, or valve.
- Usage: Type D is typically used when a female-threaded pipe or fitting needs to be connected to a male adapter.
Key Features
- Female Coupler: The cam arms on the female coupler engage with the groove on the male adapter, ensuring a tight and secure seal.
- Female Thread: The female threaded end (usually NPT or BSP) allows for connection to a corresponding male-threaded fitting or pipe.
- Materials: Available in various materials including aluminum, brass, stainless steel, and polypropylene to meet different application needs and compatibility with various fluids.
Applications
- Industries: Commonly used in industries such as agriculture, chemicals, petroleum, and water treatment.
- Function: Ideal for applications requiring a quick and secure connection between a hose and a female-threaded pipe or fitting.
