Standard & Custom Buna Rubber Gaskets

Delmar Company manufactures both ANSI-standard Buna rubber gaskets and custom Buna gaskets that match our customers’ unique design requirements. We use a state-of-the-art Atom Flashcutter to precision-cut all our Buna rubber gaskets, holding tolerances as close as ±0.008” or better on even the most complex gasket profiles.

We will work with the ANSI specs you need or from your own CAD, DXF, or DIE design files to create standard or custom Buna gaskets that perfectly match your precise specifications.

Buna Gaskets from the Experts

Also known as nitrile rubber, Buna is a synthetic rubber copolymer composed of acrylonitrile and butadiene. Numerous variations of Buna material exist, each with its own unique properties, but in general, Buna offers good resistance to oil, fuel, chemicals, and acids, as well as high strength. Buna rubber is commonly used in a broad range of applications, from automotive to medical.

The Delmar team will work with you to determine if Buna is the right material for your gasketing needs, or if another rubber gasket material would be a better choice. Material selection is based on a variety of factors, including process temperatures and pressures, chemical compatibility, sealing requirements, and more.

We use a series of questions we call STAMP to determine what material will work best for your gasket 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 valve? a pump? a flange? etc.
  • M: Media—what will the gasket prevent from leaking?
  • P: Pressure range in which the gasket will operate

Safety is Our Top Priority

Your gasket could very well fail if it’s is made from the wrong material, causing equipment damage, personal injury, or worse. That’s why Delmar Company does everything in our power to ensure that your standard and custom gaskets are manufactured from the material that is best-suited to your application.

If we aren’t 100% certain that the material we recommend will work safely in your application, we’ll help you find a material that will—even if that means sending you to another manufacturer. We won’t sell products just to make a sale; if we can’t provide the right material for your needs, we won’t sell you anything at all. Safety has always been our #1 priority.
