Standard & Custom Rubber O-Rings

O-Rings in All Elastomers for All Applications

Delmar Company manufactures high quality, high precision O-rings using a wide range of rubber elastomers. Using our advanced, CNC-powered Atom Flashcutter system, we can deliver ANSI-standard O-rings and custom O-rings with tolerances as close as ±0.008” or better, no matter how complex the design.

Working with the ANSI specs you need, or from your CAD, DXF, or DIE design files, we will produce standard or custom O-rings to match your exact specifications.

Rubber O-Rings from the Experts

Delmar Company works with a broad spectrum of elastomer materials, giving you the options you need for your application and performance requirements. We can provide:

Select specialty materials are available upon request—contact us to discuss your unique material requirements

Our expert team will work with you to establish what material is right for your needs. Material selection is based on numerous factors, including process temperatures and pressures, sealing capabilities, and chemical compatibility, among others.

We use a series of questions, which we call STAMP, to find the best and most effective elastomer for your application. Please keep the following questions in mind when specifying your standard or custom rubber O-rings:

  • S: Size of the O-ring
  • T: Temperature range in which the O-ring will be used
  • A: Application—is it a flange? a valve? a pump? etc.
  • M: Media—what will the O-ring prevent from leaking?
  • P: Pressure range in which the O-ring will be used

FDA & NSF 61 O-Rings

For food, beverage, and potable/drinking water applications, we can produce ANSI O-rings and custom O-rings from a number of FDA-approved and NSF 61-approved elastomers.

Safety is Our #1 Priority

Choosing the right material for your O-rings is critically important, as the wrong material can lead to O-ring failure, material damage, personal injury, or worse. That’s why Delmar Company does everything we can to ensure that your O-rings are manufactured from the best and most effective material for the task at hand.

If we’re not 100% sure that the material we recommend will work safely in your application, we’ll do our best to find a material that will—even if that means sending you to a different manufacturer. We don’t sell products just to sell products; if we can’t provide the material you need, we won’t sell you anything at all. Safety is, and always will be, our top priority.
