Fiberglass Gaskets & Sealing Materials

Delmar Company is a leading manufacturer of high precision standard ANSI fiberglass gaskets, custom fiberglass gaskets, and custom-cut fiberglass sealing materials. Because it won’t burn or melt, fiberglass is an ideal material for gaskets and sealing products used in challenging applications where temperatures may reach up to 1,000°F (538°C).

We utilize a state-of-the-art Atom Flashcutter to manufacture fiberglass gaskets with superior precision and perfect repeatability from the first piece to the ten-thousandth and beyond. With advanced CNC capabilities, our system maintains tight tolerances within ±0.008”; it can cut fiberglass material as thick as 1/2”.

We will work from your ANSI specs (for “standard” gaskets) or CAD, DXF, or DIE design files (for custom gaskets) to produce sealing products that meet your exact specifications.

Standard & Custom Fiberglass Gaskets from the Experts

With its high temp and high wear characteristics, fiberglass may be your first choice of materials for your gaskets. However, it may not actually be the best option for your unique needs. Our expert team will work with you to ensure that the standard or custom gaskets we provide are made from the best, most effective, and safest material for your application. Material selection is based on several key factors, including process pressure and temperature, chemical compatibility, and sealing capabilities.

We use a series of questions, which we call STAMPS, to help us find the right material for your gaskets. 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 must operate
  • A: Application—is it a valve? a heat exchanger? a pump? etc.
  • M: Media—what will the gasket prevent from leaking?
  • P: Pressure range in which the gasket must operate

Safety is our #1 Priority

Selecting the right material for your gaskets is supremely important. Using the wrong material can cause gasket failure, personal injury, or worse. To that end, we do everything in our power to guarantee that your standard or custom gaskets are made with the best material for your particular application.

If we aren’t 100% certain that the gasket material we recommend will work safely in your application, we will help you find the right one for the job—even if that means sending your project to another manufacturer. We don’t want to sell products just to sell products; if we can’t provide the material you need for safe operation, we won’t sell you anything at all. Safety always comes first.
