Surgical plastic tubing often comes coiled, but there are several ways to straighten it. One method is to use steam: cut the end of the tube square, slip a wire inside, and tape off one end, leaving an inch of wire exposed. Boil a small amount of water in a kettle, then hold the wire in the steam until water condenses inside the tube. Remove the tubing from the steam, place it on a flat surface, and allow it to cool. You can also use heat, such as a hairdryer, to straighten the tubing. If you have access to a yard, you can also try stretching the tubing in the sun for a day or two.

What You'll Learn
Use a hairdryer
Using a hairdryer is an effective way to straighten surgical plastic tubing without compromising the material.
First, turn on your hairdryer and select a suitable heat setting. It is recommended to start with a lower heat setting to avoid damaging the plastic tubing. Hold the hairdryer at a comfortable distance from the tubing—approximately 6 to 12 inches away. Starting from one end of the tubing, slowly move the hairdryer back and forth along the length of the tube. Ensure that you evenly distribute the heat to avoid overheating any specific area.
As the plastic tubing begins to heat up, you will notice it becoming more pliable and easier to manipulate. At this point, gently bend and straighten the tubing with your hands, guiding it into the desired shape. Be careful not to apply excessive force, especially if the tubing is thin or delicate. It is important to work quickly during this step as the plastic will start to harden again as it cools down.
Once you have achieved the desired straightness, turn off the hairdryer and allow the tubing to cool naturally. You can speed up the cooling process by gently waving a piece of cardboard or a flat object in front of the tubing to direct air onto it. Alternatively, you can leave the tubing undisturbed for a few minutes until it reaches room temperature.
If the tubing does not straighten sufficiently on your first attempt, you can reapply heat using the hairdryer and repeat the process. It is important to be cautious and avoid overheating the plastic to prevent any damage or melting.
Using a hairdryer is a convenient and controlled method for straightening surgical plastic tubing. It allows you to direct heat onto the tubing gradually and make adjustments as needed. With this method, you can effectively straighten the tubing while maintaining the integrity of the material.

Try a heat gun
To straighten surgical plastic tubing, one method you can try is using a heat gun. Heat straightening is a common technique for reshaping plastic tubing. It involves using a heat gun or hot water to soften the tubing, allowing you to manually manipulate it into the desired shape.
When using a heat gun, it is important to exercise caution to avoid damaging the tubing. Set the heat gun to low heat and gently warm the tubing. You can then reshape it by hand or with a straightening device. Move the heat gun slowly along the length of the tube to ensure even heating. Be careful not to overheat the tubing, as this can cause warping or other deformations.
To achieve the best results and prevent kinks, use an object like a dowel or rod to guide the tubing into the desired shape as you apply heat. This will help ensure that the tubing cools and sets in a straight line. It is also recommended to stretch the tubing straight and leave it for a period of time to help it retain its new shape.
The heat gun method can be particularly useful for straightening longer lengths of tubing, as it allows you to work in sections and gradually straighten the entire length. This technique may require some trial and error to find the right temperature and distance to hold the heat gun from the tubing.
While the heat gun method can be effective, it is important to note that it may not work for all types of plastic tubing. Some tubing materials may be heat-sensitive, so it is crucial to research the specific type of tubing you are working with and take the necessary precautions to avoid damage.

Straighten with steam
To straighten surgical plastic tubing with steam, follow these steps:
First, cut the end of the tube square. This will allow the steam to enter and stay inside the tube. Next, slip a wire into the tubing and use tape to close off the end. Leave about one inch of wire sticking out of the non-closed-off end. Place a small amount of water in a kettle and bring it to a full boil. With the water boiling, place the wire into the kettle's spout opening, going in as far as possible until the tubing reaches the spout. Ensure you are wearing gloves for safety.
Keep the tube end over the opening until you see water condensing inside, then remove the tubing from the steam. At this point, you can take the tubing off the wire and place it on a flat surface to cool at room temperature. This process should take around 10 minutes. Once the tubing has cooled, you can remove the wire, and you will be left with a straight piece of tubing.
Using steam is an effective way to straighten plastic tubing, but it is important to exercise caution as steam is hot and can cause burns.

Insert a metal rod and boil
To straighten surgical plastic tubing, one method is to insert a metal rod and boil. This technique is effective and straightforward, and it can be done with household items. Here is a step-by-step guide:
First, ensure that you have the necessary materials: a pot of water, a stove or heat source, and a metal rod that fits inside the tubing. The metal rod can be a simple metal dowel or even a wooden rod with a metal coating. It is important to ensure that the metal rod is clean and free of any debris or substances that may damage the tubing during the process.
Next, fill the pot with water and place it on the stove. Turn on the heat source and bring the water to a boil. While you wait for the water to reach the boiling point, you can prepare the tubing by ensuring it is clean and dry. If the tubing has been coiled for a long time, it may be helpful to first stretch it out as much as possible manually.
Once the water is boiling, carefully insert the metal rod into the center of the plastic tubing. Take precaution during this step to avoid scalding yourself with the hot water or steam. Ensure that the metal rod is securely inserted and does not move around within the tubing.
Then, carefully lower the tubing with the metal rod into the boiling water. Hold it in place with tongs or a similar tool to avoid burning yourself. Keep the tubing in the boiling water for a few minutes. The exact duration will depend on the thickness and material of the tubing, but it is generally recommended to start with lower temperatures and shorter intervals to avoid overheating the plastic.
After heating the tubing, carefully remove it from the boiling water. You can now remove the metal rod from the tubing. At this stage, the tubing should be pliable and ready for reshaping. Use caution as the tubing and metal rod will be hot. It is recommended to wear heat-resistant gloves if possible.
Finally, gently straighten the tubing by hand or with a straightening device. You can also use the metal rod to guide the tubing into the desired shape. Hold the shape until the tubing cools down and sets in its new form. If the tubing is not completely straight or you are not satisfied with the results, you can repeat the process, being careful not to overheat the plastic.
This method of inserting a metal rod and boiling is a simple and effective way to straighten surgical plastic tubing. It is important to be cautious when working with hot water and metal objects, but with care, this technique can provide good results.

Hang outdoors
To straighten surgical plastic tubing and hang it outdoors, you can try the following methods:
Using Heat
- Use a hairdryer or heat gun: Apply heat to the tubing with a hairdryer or heat gun while straightening it with your hands. Be careful not to overheat the plastic, as it may warp or melt.
- Hot water: Boil water and use a metal rod or wooden stick to straighten the tubing. This method is safer than direct heat application and is effective in shaping the tubing.
- Sunlight: Hang the tubing outdoors in direct sunlight for a day or two. The heat from the sun will help straighten it.
Mechanical Methods
- Insert a dowel: Insert a thin wooden dowel or rod inside the tubing and then heat it in an oven. This method may be limited by the length of the tubing and the size of the oven.
- Straighten against a board: Straighten the tubing against a flat surface, such as a board, and use a hairdryer or heat gun to apply heat while holding it in place.
When hanging the tubing outdoors, ensure that it is securely attached at both ends to prevent it from being affected by wind or other environmental factors that may cause it to bend or move.
