Product Gallery



Extruded tubing serves multiple different purposes in the medical industry, from fluid transfer, air and water transfer, to medication distrubution and catheters.


In the Aero industry, plastic tubing is used for a variety of fluid transfers as well as coatings for sensitive electronic components.


Extruded tubing is essential throughout the automotive industry with a variety of uses including coating for sensitive electrical wires as well as carrying brake fluid, steering fluid and coolant.


Most medications dispensed by a medical device require very precise doses at very carefully controlled speeds. For that reason, having the appropriate size and configuration of tubing is essential to the Pharma industry.


There are numerous applications in the dental industry for extruded tubing, ranging from implants and braces to medication distribution.


Extruded plastic has always been an important element of the energy industry. The durability, flexibility, and resistance to electrical current makes it ideal for coating many wires and other sensitive components.


As communication technology continues to grow, so does the need for insulator tubing that is vital to the protection of the fiber optic cables carrying this important information. Our custom extruded tubing can be color matched or striped for easy identification when multiple strands are needed for complex jobs.

Fluid Management

Our tight tolerance tubing can play a role in providing precise and consistent fluid flow for a wide range of industries. From brake lines to dialysis we can customize your tubing requests to the exact measurements and tolerances required to meet your individual needs.
