Standard & Custom EPDM Rubber Gaskets

Delmar Company is the #1 source for ANSI-standard EPDM rubber gaskets and custom EPDM rubber gaskets for all applications. We utilize a state-of-the-art, CNC-operated Atom Flashcutter to produce even the most complex gasket profiles with exceptional precision, tight tolerances within ±0.008” or better, and perfect repeatability.

Based on either the ANSI specs you need or your CAD, DXF, or DIE design files, we will produce standard or custom EPDM rubber gaskets that meet your unique requirements.

EPDM Rubber Gaskets from the Experts

EPDM (ethylene propylene diene monomer [M-class]) is a type of synthetic rubber material. The exact chemical makeup varies across a family of EPDM grades, but all EPDM rubber exhibits the same general characteristics: outstanding heat, ozone, and weather resistance, good resistance to ketones and ordinary diluted acids, and good compatibility with hydraulic fluids, hot and cold water, and alkalis. EPDM rubber is therefore ideal for a broad spectrum of gasketing applications.

Delmar Company will work with you to establish whether or not EPDM rubber is the right material for your application, or if a different rubber gasket material is better-suited to your needs. Proper material selection depends on a number of factors—process temperature and pressure, chemical compatibility, sealing capabilities, and more.

We use a series of questions, which we call STAMP, to help find the best material for the gaskets you need. 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 be used
  • A: Application—is it a valve? a flange? a pump? etc.
  • M: Media—what will the gasket prevent from leaking?
  • P: Pressure range in which the gasket will be used

NSF 61 Approved EPDM Rubber Gaskets

If you need gaskets for potable drinking water applications, Delmar can provide special NSF 61-approved EPDM rubber. We are one of few companies in the industry that works with NSF 61 rated elastomers. Contact us to discuss your NSF 61 gasket requirements.

Safety is Our Top Priority

Finding the right material for your gaskets is extremely important—if the wrong material is used, gasket failure, equipment damage, personal injury, or worse could occur. With that in mind, we do everything in our power to ensure that we use the best, most effective material when manufacturing your standard or custom gaskets.

If we aren’t 100% positive that the gasket material we recommend will work safely in your application, we’ll help you find the right material for your needs, even if that means sending you to another supplier. We will never sell you a product just to make a sale; if we can’t provide the right material for the job, we won’t sell you anything at all. Safety is, was, and always will be our #1 priority.
