What Is a Coupler?
A coupler is a nozzle at the end of a hose or a connection between hoses.
It is made of metal, and a little damage to the body will not cause damage or loss of performance. A wide variety of sizes are available to match the diameter of the hose to be connected.
The coupler can be easily connected to or disconnected from the grease nipple by squeezing the lever on the main body of the coupler. The coupler supplies grease to the grease nipple without waste and helps improve the efficiency of greasing operations.
Uses for Couplers
Couplers are often used when watering agricultural fields or applying liquid fertilizer. They are necessary to secure a nozzle to the end of a hose. In addition, the hoses can be connected and their lengths can be freely adjusted, even in remote areas.
The hose can be used in any agricultural area, but it is most useful in areas and seasons where rainfall is relatively low and water is supplied by sprinkling. The connection itself is a one-touch connection and is an effective tool because it does not leak. Since it does not require special tools or force, it can be handled by women, children, and older people with arm strength.
Features of Couplers
Pros
Couplers have the advantage that anyone can quickly and easily connect and disconnect pipes and hoses. They can also be attached precisely with a single touch without the need for difficult operations, eliminating the risk of leakage.
The socket and plug are locked by fitting them together, and the valve opens and closes automatically as they are attached and detached. Thus, while liquids and other liquids flow when connected, they automatically stop and do not leak when the coupler is disconnected.
Although rarely used in agriculture, they can be used to transport not only liquids but also gases and oil, making them useful in a variety of situations.
Disadvantages
Couplers must be the right size for the diameter of the hose or pipe. Because they are not adjustable, they cannot be used with hoses or pipes of different diameters.
Before purchasing a coupler, measure the diameter in advance, and also be careful when replacing hoses.
Types of Couplers
Couplers are available in a variety of sizes to match the diameter of the hose or pipe.
Materials include silicone, steel, brass, and stainless steel. When used in the field, you do not need to worry too much about the temperature of the liquid because the temperature change of the liquid is small, but you need to consider whether it is suitable for the temperature of the liquid to be flowed.
How to Select a Coupler
The most important factor in choosing a coupler is its diameter. Since the size cannot be adjusted after purchase, it is necessary to measure the diameter of the hose or pipe and select the correct size.
Also, different materials can handle different temperatures of fluids, so it is important to check carefully before selecting the right one. The pressure of the fluid must also be considered. If the pressure is considered to be strong, a product with excellent pressure resistance should be selected.
When connecting two hoses, a standard straight coupler is used, but if three hoses need to be connected, a coupler for three hoses should be selected.
How to use a Coupler
Couplers consist of a male part called a plug and a female part called a socket. Each plug is attached to a hose, and the couplers are connected. When you want to stop the flow, disconnect the couplers and the valve will automatically close to stop the flow.
If the couplers on the hoses you want to connect are either male or female, you will not be able to connect them. However, some products have male or female couplers on both ends for connecting these hoses.
Currently, many couplers can be connected with a one-touch connection, allowing for easy installation and use. If the coupler is not installed properly or is shallow, the pressure of the fluid may cause the coupler to come off, leading to an accident. It is important to confirm that the coupler is securely attached before starting to use it.
