Standard & Custom Silicone Rubber Gaskets

Delmar Company manufactures high quality silicone gaskets in both ANSI-standard profiles and custom configurations to meet our customers’ needs. Our state-of-the-art Atom Flashcutter system allows us to maintain exceptional precision and hold tight tolerances as close as ±0.008” or better, no matter how complex the gasket design.

We will work from any ANSI spec you require, or from your CAD, DXF, or DIE design files to deliver standard or custom silicone rubber gaskets that match your exact specifications.

Silicone Gaskets from the Experts

Silicone rubber is a widely used elastomer that is available in multiple formulations. In general, silicone rubber exhibits good resistance to, and the ability to maintain its other properties at, extreme temperatures (from -100° to 300°C/-148° to 572°F). The material holds its initial shape and retains its mechanical strength under heavy thermal stress and in sub-zero temperatures. Silicone is highly inert and non-reactive with most chemicals, making it an ideal choice for medical applications and implants.

The experts at Delmar will work with you to determine if silicone rubber is the best option for your gaskets, or if a different rubber gasket material would be better suited to your needs. Material selection is based on a number of factors, including process temperatures and pressures, chemical compatibility, and sealing requirements, among others.

We use a series of questions, which we call STAMP, to help us establish what material will work best for your application. Please keep the following questions in mind when specifying your standard or custom gaskets:

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

Safety is Our #1 Priority

If it’s made from the wrong material, your gasket could fail, causing equipment damage, personal injury, or worse. With that in mind, Delmar Company does everything we can to ensure that your standard and custom gaskets are manufactured from the right 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 point you toward a material that will, even if that means sending your project to another supplier. We don’t sell products just to make a sale—if we can provide the right material for your needs, we won’t sell you anything at all. Safety is always our first priority.
