Benefits of Polyurethane Tubes
Strong & Durable. Versatile. No Cracks, Tearing or Swelling.
Many organizations rely on urethane tubes for a variety of applications. Urethane tubes result in a stronger, more durable, and more versatile product. PU tubes are commonly viewed as a better value, because tubes made with other materials often crack, tear, and swell.
Common Applications Include:
- Slide Over Cores for Rollers
- Protective Sleeves
- Vibration Isolators
- Bumpers
- Sound dampening

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 exactly. 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 an ID/OD combination that we have never produced, please note there may be a small setup charge for machining a top and base.

Frequently Asked Questions
Here are quick answers to common questions about our tubes.
What is a polyurethane tube?
A polyurethane tube is a cast PU cylinder with a defined ID, OD and length, molded to a chosen durometer for strength, abrasion resistance and vibration dampening without the cracking, tearing or swelling of rubber or plastic tubes.
What sizes and tolerances can PSI produce?
PSI casts tubes from .375″ through 1.75″+ inner diameters in lengths up to 36″, on in-house molds held to an “On Mandrel” tolerance (±.063″ OD), with custom ID/OD combinations available.
What hardness range is available for urethane tubes?
From 20 Shore A to 90 Shore A and 50 Shore D to 75 Shore D, plus static-dissipative material (25 OO to 70D) and FDA dry and wet food-approved options.
Are PSI polyurethane tubes food safe?
Yes. PSI offers FDA Dry food-approved tubes from 30A to 65D and FDA Wet food-approved tubes from 30A to 90A.
What are polyurethane tubes used for?
Common uses include slide-over cores for rollers, vibration isolators, sound dampening, protective sleeves and bumpers.
