Urethane Tubes

Cast Urethane Tube

PSI produces custom cast tubes from our premium grade urethane to withstand a wide range of applications.

Customized To Your Specifications

All urethane tubes are customized to your specifications of diameter, length, hardness, and color. PSI also offers custom formulations to meet your specific application as well as FDA dry or wet food approved.

Customization Options –

  • Diameter
  • Length
  • Hardness
  • Color
  • Tolerance
  • Shape
  • And More!

Our in-house machining capabilities can provide tight tolerances and a ground finish for your polyurethane tubing. When specialty parts are needed we can produce Dual Durometer polyurethane tubes and custom shapes.

Urethane Tubes Advantages

Many organizations rely on urethane tubes for a variety of applications. Urethane tubes result in a stronger, more durable, and more versatile product. They are commonly viewed as a better value, because tubes made with other materials often crack, tear, and swell.

  • Strong & Durable
  • Versatile
  • No Cracks, Tearing, or Swelling

Common Applications Include:

  • Slide Over Cores for Rollers
  • Protective Sleeves
  • Vibration Isolators
  • Bumpers
  • Sound dampening
  • And more

With a long history of outstanding quality, superior product performance and excellent customer service, PSI is a trusted provider of both custom and standard urethane tubes.

Standard In House Tube Molds

Below is a chart of the ID and OD dimensions that we have molds for in house.  All ID’s listed have an “On Mandrel” tolerance, which means we pour them exact.  In its relaxed state,  the ID will shrink down and will measure smaller than the dimension it was poured.  Since polyurethane is an elastomer, it will stretch back out to the requested ID and will be a tight fit.

We have the ability to take our existing molds and customize tubes specific to your requirements.  If you need a id/od combination that we have never produced, please note there may be a small setup charge for machining a top and base.

Understanding Urethane Tubes: Benefits, Applications, and Choosing a Manufacturer

Consider the following when selecting a urethane tube manufacturer:

  • Review their list of tube specifications. This includes looking at diameter, length, hardness and color to ensure you are getting the best product for your unique needs.
  • Meet with their customer service professionals. You want to work with a team that responds to your inquiries quickly and has the knowledge and expertise to meet all of your needs.
  • Understand their production process. Do they provide in-house manufacturing and specialty parts when needed? This can make your process faster and less expensive.
