Urethane O-Rings – Custom Urethane O-Rings

Urethane O-Rings are a great solution when traditional o-rings fail or are not available in the size for your custom application. Urethane o-rings are typically molded to size using compression molding. This will yield parts to print with no secondary process saving you money! Urethane o-rings are available in all durometers and sizes. A variety of additives can be added to enhance wear properties or abrasion resistance. A metal detectable additive can also be added for X-ray equipment required for FDA applications. We also cast FDA Dry food approved Urethane o-rings.

Polyurethane o-rings can be molded with any added thru hole for a hinge or any other configurations as well. We can also make custom urethane o-rings without the traditional circular style if your custom application requires a different shape for the polyurethane o-ring. Urethane is a great choice for high pressure sealing devices due to the ability to tailor our chemicals in our state of the art urethane manufacturing facility. We can provide any hardness needed for your application or sealing needs. Custom urethane o-ring sizes are no problem for us here at Plan tech.

Plan Tech offers waterjet cut urethane parts utilizing a “state of the art” Flow Dynamic 4′ x 8′ Integrated Flying Bridge waterjet cutting machine. The dynamic head virtually eliminates the taper normally associated with waterjet cutting while improving cutting speeds, part accuracy and tolerances in cutting flat stock materials.

Our capabilities include:

  • Taper elimination by Active Tolerance Control
  • Versatility – cut with water only or abrasive
  • Secondary finishing elimination
  • Part tolerance and geometry improvement
  • True part stacking ability with consistent tolerance layer to layer
  • Vacuum assist technology for carbon fiber and other laminates


Some of the materials we can cut include:

  • Polyurethane, all durometers
  • Polyurethane laminates of metallic and non-metallics
  • Reinforced polyurethanes
  • ArmorglideTM polyurethanes
  • Steel, Stainless, Aluminum, Brass, Titanium, Copper
  • Rubber, Silicone
  • Silicone Foam, Foam Rubber, Polyurethane Foam
  • PEEK, Acrylic, Nylon, Delrin, PTFE/Teflon, ABS, Acetal
  • Carbon Fiber, Kevlar, Fiberglass
