Using a pump
Inflating a plastic inner tube using a pump is a convenient and efficient way to get the job done. It is important to note that tubes require more air pressure than human lungs can muster, so using a pump ensures your tube is inflated for optimal performance and minimal wear and tear. Here are the steps and considerations for using a pump to inflate a plastic inner tube:
Firstly, it is essential to choose the right pump for the job. A good pump is critical to achieving the recommended pressure for your inner tube. Hand pumps, such as double-action hand pumps, are well-suited for inflating inner tubes as they can help reach the desired pressure quickly. These pumps work by providing air during both the up and down strokes, resulting in faster inflation. Electric air pumps are another option, offering precise inflation pressure control, although they may require a car cigarette lighter socket for power. When selecting a pump, ensure it can provide the necessary pressure and that the pump's tips are compatible with your inner tube's valves.
Before inflating, it is helpful to understand the recommended pressure for your specific inner tube. Different tubes have varying pressure requirements. For example, float tubes with air chambers are typically inflated to around 2.5 Psi, while PVC float tubes may require 3.5 to 4 Psi. Some manufacturers display the inflation pressure on the valve, so be sure to check this information before starting. Respecting the recommended pressure is crucial for ensuring the tube's bearing capacity and glide performance on the water.
Now, let's move on to the inflation process. If using an electric pump, select the appropriate fitting for your inner tube's valve type. For a stem valve, the fitting should be inserted into the valve, ensuring the pointy end goes in deep enough to open the gate. Then, start the pump to initiate inflation. When using a hand pump, a similar process applies—connect the pump to the valve and start pumping. It is beneficial to have a pressure gauge to monitor the air pressure and ensure you reach the desired level without overinflating.
Lastly, it is important to remember that the inner tube's pressure can be affected by temperature. When the tube comes into contact with cold water, the pressure can drop, giving the impression that it is deflated. Therefore, it is recommended to slightly overinflate the tube to compensate for any pressure loss. Additionally, consider bringing the pump with you to adjust the pressure or address any leaks, especially if you are new to using inflatable tubes.

Adjusting for temperature
Adjusting air pressure in a float tube is important as the air pressure is not the same according to the temperature of the water and the external temperature. On a hot day, it is not advisable to over-inflate the float tube as the pressure inside will increase. If the pressure becomes too high, you can slightly open the valves to adjust it. Conversely, on a cold day, it is recommended to inflate the float tube to its maximum capacity to allow time for the pressure inside to adjust. If necessary, adjust the pressure once you are done with the preparation and are ready to put it in the water.
It is also important to take a pump with you to adjust the pressure or prevent any leaks, especially if you are new to this type of boat. A good pump is essential to inflate a fishing float tube according to the manufacturer's recommendations. The pump is not always supplied with the purchase of a float tube, and sometimes the supplied pumps are insufficient to reach the necessary pressure. Therefore, depending on the brand of the float tube, you might have to buy a pump separately. For instance, electric air pumps can be plugged into a car cigarette lighter socket to obtain a precise inflation pressure.
When inflating, make sure to place the float tube on a surface with as few objects as possible that could damage it. A quick inspection of the place where the float tube is to be placed is necessary to avoid any damage. It is also important to closely monitor the raft as it fills with air. If the suction between the pump and the fill-hole is intact, you can increase the speed of the air pump to "high". If the suction seems weak, you might need to hold it together with your fingers and keep the setting on "low".

Valves and pressure
Some inner tubes have a stem valve, which is the simplest type of valve. To inflate a stem valve, use an electric pump with the appropriate fitting. Insert the fitting deeply into the stem valve to ensure that the gate for the valve is broken open. Then, start the pump to inflate the tube. You can pinch the stem valve to release air from it.
The pressure required to inflate an inner tube depends on the type of tube and the temperature of the water and external environment. For example, float tubes with air chambers inflate to around 2.5 Psi, while PVC float tubes inflate to around 3.5 to 4 Psi. Dropstitch float tubes are inflated to a higher pressure of 15 Psi. It is important to respect the recommended inflation pressure to ensure the tube has good bearing capacity and glides well on the water.
On a hot day, it is advisable not to over-inflate the tube, as the pressure inside will increase due to the heat. If the pressure becomes too high, the valves can be opened slightly to adjust the pressure. In contrast, on a cold day, it is recommended to inflate the tube to the maximum pressure, as cold temperatures reduce the air pressure in the tube. If necessary, the pressure can be adjusted later when the tube is in contact with the water.
To reach the desired pressure, a double-action hand pump is a suitable option. This type of pump sends air in both directions, allowing for quick inflation. It is important to ensure that the pump has a pressure gauge to control the air pressure accurately. An electric air pump that plugs into a car cigarette lighter socket can also provide precise inflation pressure. However, it is crucial to check the maximum pressure a pump can achieve before purchasing it and ensure that the pump's tips correspond to the valves of the inner tube.

Inflating hybrid models
When it comes to inflating hybrid models of float tubes, there are a few key considerations to keep in mind. Firstly, hybrid models may require different inflation pressures for different parts of the tube. For example, the junior flatform is inflated to 3.6 Psi on the sides and 15 Psi in the centre. It's important to respect the manufacturer's recommended inflation pressure to ensure optimal bearing capacity and glide on the water.
The external temperature and water temperature also play a role in inflating hybrid models. On hot days, avoid over-inflating the float tube as the pressure inside will increase due to the heat. If the pressure becomes too high, you can slightly open the valves to adjust it. Conversely, on cold days, it is advisable to inflate the float tube to its maximum capacity upon arrival to allow time for the pressure to adjust. If needed, you can fine-tune the pressure once you're ready to put the tube in the water.
It's a good idea to bring a pump with you to adjust the pressure or address any leaks, especially if you're new to using float tubes. While some float tubes come with pumps, they may not always be suitable or sufficient to reach the necessary pressure. In such cases, a hand pump, particularly a double-action hand pump, is recommended as it allows for quick and efficient inflation to the desired pressure.
When choosing a pump, it's essential to consider its maximum pressure capacity and ensure that the pump tips correspond to the valves of the float tube. Additionally, a pressure gauge is a valuable feature to help control the air pressure. Electric air pumps that plug into a car cigarette lighter socket are another option, providing precise inflation pressure and freeing up time for other tasks.
