What Is Extruded Plastic Tubing?

What Is Extruded Plastic Tubing?

Extruded plastic tubing is a thin, hollow tube made of plastic usually used for pipes and hoses in plumbing systems or other applications requiring a hollow structure. The manufacturing process involves forcing the plastic through a heated die to produce the desired shape.

The finished plastic extruded tubing has a smooth outer surface and a hollow interior that can be filled with air or liquids. The strength of extruded plastic tubing depends on its thickness and weight and the type of material used during manufacture.

What Industries Are Extruded Square Plastic Tubing Used for

Plastic extruded tubing is used in many industries, such as:

Automotive Industry

Extruded plastic tubing is used in the automotive industry to make various products, including fuel lines and radiator hoses. The tubing is also used to produce air intake ducts and intercoolers.

Construction Industry

In the construction industry, extruded plastic tubing is used to make piping for sprinkler systems and fire sprinkler systems.  The material can also be used to make plumbing pipes, which are ideal because they are lightweight yet strong enough to withstand high pressures and temperatures.

Agriculture Industry

The agriculture industry relies heavily on extruded plastic tubing because it’s durable and easy to clean, which makes it especially useful for storage tanks used for storing animal feed or water.

By using extruded plastic tubing in these tanks, farmers can easily access any part of their equipment without having to remove it from their property.

Food Packaging Industry

The food packaging industry uses extruded plastic tubing to make various food and drink containers. Plastic tubes are used to manufacture bottles, jars, cans, and other containers for beverages, dairy products, and other liquids.

The tubes provide an airtight seal that protects these products from contamination or degradation due to oxygen exposure.

Plumbing and HVAC Systems Industry

Plumbing and HVAC systems are two of the most common industries that use extruded plastic tubing. Plumbing systems use polyvinyl chloride (PVC) pipes for water supply lines, drain lines, and venting systems.

HVAC systems rely heavily on extruded polyethylene (PE) pipe to transport refrigerants or gasses like propane or natural gas through their system.

Medical Devices Industry

Medical devices such as stents, catheters, and IV bags are used in hospitals worldwide every day. These products must be highly durable to withstand high pressures, temperatures, and exposure to chemicals found in hospitals without breaking down over time.

Extruded plastic tubing is often used in these medical devices because it meets these requirements while also being FDA approved for use with human bodies.

What Are the Benefits of Plastic Extruded Tubing

Extruded plastic square tubing is an excellent option for many industrial and commercial applications. The following are some of the benefits of extruded square plastic tubing:


Plastic extruded tubing is lightweight and easy to handle. It can be easily cut, welded, and joined together without losing strength or quality. The material is also very strong and durable, making extruded plastic square tubing an excellent choice for many applications.


Extruded plastic square tubing is flexible and can bend in any direction without breaking or kinking like other types of tubing. This makes it ideal for use in tight spaces where traditional materials would not fit or be able to bend as easily.

Corrosion Resistant

Plastic extruded tubing is not susceptible to corrosion like other types of metal. It does not rust or corrode like steel or aluminum, making it an excellent choice for use in areas exposed to moisture or harsh environments, such as septic tanks, wastewater treatment plants, farmlands, and golf courses.


The durability of the extruded plastic square tubing is due to the fact that it’s made from a polymer material. The polymers are formed into tubes with a hard shell that protects the inside from damage and other elements, making extruded square plastic tubing an excellent choice for many projects in different industries.

Heat Resistant

Extruded square plastic tubing can be used in very high temperatures because it’s made with heat-resistant polymers, making it an excellent material for many different applications and industries, such as automotive and aerospace industries, as well as plumbers’ and electricians’ tool sets.


Plastic extruded tubing is also one of the safest materials in many industries because it’s non-toxic and contains no harmful chemicals that could cause an issue if someone were exposed to them or ingested them by accident.
