Graphite Gaskets & Graphite Sealing Products

Delmar Company manufactures high precision standard ANSI graphite gaskets and custom graphite gaskets, as well as custom-cut sealing products from graphite sheet. Graphite gaskets and sealing products are ideal for a broad spectrum of applications with process temperatures up to 900°F (482°C).

Using a state-of-the-art Atom Flashcutter, we can produce graphite gaskets and graphite sealing products with exceptional precision and perfect repeatability from the first piece to the last. This CNC-powered system provides dimensional accuracy within ±0.008” for materials as thick as 1/2”.

We will work with your ANSI specs or CAD, DXF, or DIE files to create standard or custom gaskets that match your unique requirements.

Standard & Custom Graphite Gaskets from the Experts

While graphite may offer many of the attributes your process or application needs, it is important to guarantee that you’re using the best gasketing and sealing material for your specific application. Our expert team will help you select the right material for your project. Material selection is based on numerous factors, including process pressure and temperature, chemical compatibility, sealing capabilities, and more.

We use a series of questions, which we call STAMPS, to find the right material for your gasketing application. Please keep the following questions in mind when specifying the standard or custom gaskets you need:

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

Safety is Our #1 Priority

If the material is not up to the task, it can cause gasket failure, personal injury, or worse. That’s why Delmar does everything in our power to ensure that the standard or custom gaskets we produce are made from the best, most effective material for the job.

If we aren’t 100% certain that the material we recommend will work safely in your application, we will help you find the right product for the job, even it if means sending your project to another manufacturer. We won’t sell you a product just to sell a product—if we can’t provide the right material for your application, we won’t sell you anything at all. Safety is, was, and always will be our #1 priority.
