EPDM Gaskets: Not Every Gasket Is The Same

epdmgasketsGaskets allow for successful, in-abrasive and unobstructed communication between necessary mechanical parts. Such relay transaction occurs in all industries at some level from household blenders to vehicle oil chambers to amusement park swivelers to medical suturing equipment and beyond. Gaskets not only permit production but also function to elongate the lifespan and integrity of costly machinery. Gaskets do not vary in this general purpose, only in materials and design specifications as required for certain purposes. Unless you are an entrepreneur, shop operations manager, or artist, you won’t know that you’re in need of a gasket until it has failed, worn out. When determining the best gasket seals for your task, consider the following 3 stages:


More often than not, however, you will simply reorder the part per indicated contact or local repair shop consultation.

Assessing the best materials for the job requires a professional examination of the range of generated pressure tension and temperature, vibration, resistance and liquid access threat, among other more scientific and technical matters that you, as a consumer, need not worry about unless you’re planning on studying related engineering. Leave it all to the experts, and they will ask you all relevant questions to gather accurate data before suggesting a gasket solution. Do feel free, however, to ask questions from your perspective and the seasoned professional will be glad to paint the picture for you in your terms. Also note, there are a number of official entities that certify proper manufacture of gaskets. These regulations involve the purpose for use, plus the possible contact with other material during use. Think food blenders, for example.

Common uses for gaskets and their composition include seal, sound dampening, agitation control, sheet cutting gaskets, spiral wound gaskets, double jacketed gaskets, kammprofile gaskets and flange gaskets. Pressed sheet gaskets are valued for their custom designs and inertia to corrosive liquids, and are usually comprised of graphite, mineral, carbon, or nitrile synthetic rubber. Spiral wound gaskets rely on centrifuge dynamics where clamping is discouraged, and are comprised of a metallic outer support band working in conjunction with an inner filler typically made of graphite or other flexible material for tolerance. Double jacketed gaskets are similar in that they make use of the outer/inner or support/filler style of sealing a process next to a piece. They are usually shaped as a tubular “C.” Kammprofile gaskets are appreciated for their longevity and reliability of performance. They use a system somewhat opposite that of the spiral wound and double jacketed because the solid supportive material, typically a corrugated solid, is the inner material and the flexible graphite occurs in its surround. Flange gaskets are common as they function to vacuum seal the operative connections along pipelines and are commonly made of red rubber because it works well with hot and cold water, air and steam.

Making gaskets is best left to seasoned technicians. While each will have studied similar curriculum content, as with any skill time and experience engender that sixth sense of selecting and designing to the customers’ aims. Getting a guarantee from your manufacturer almost sounds counter-intuitive because, today, we generally think in terms of life not having any guarantees. However, the temperature and pressure specifications and design regulations inherent in making gaskets are so clear as to warrant true guarantees, not smoke or false assurance. The key, though, is clarity in explanation of purpose, longevity needs, and accuracy regarding measurements and relating parts.

The most useful type of gasket composition is made of EPDM for its versatility and durability. It is a synthetic rubber and its acronym stands for Ethylene~Propylene~Diene~Monomer. It can be designed to any customized size and shape. It endures extreme weather. And it has all of the pressure strength indicators to fulfill any function not excessively exposed to fuels and oils.
