Die Cut Rubber Gasket

Putting Different Die Cut Rubber Gasket Characteristics to the Test

Die-cut rubber gaskets are used for a vast array of applications, especially sealing water. However, not all die-cut gaskets are created equally. When choosing the best die-cut gasket or seal, there are a number of different considerations that should be made. 

One of the top considerations is the type material and the characteristics it offers your custom gaskets. Fortunately, the team at Frank Lowe can help. We offer decades of experience creating die-cut gaskets from rubber and other types of nonmetallic gasket material. 

As such, we have gained volumes of in-depth knowledge and understanding of each type of custom die-cut rubber material. Continue reading for an overview of the most common types of rubber materials used in die-cut gaskets, ring joints, and other parts.

Silicone Rubber Die Cut Gasket and Seal

Gaskets and seals manufactured from silicone rubber will retain excellent elastomeric properties at both low and high temperatures. Gaskets made of silicone rubber boast excellent resistance to weathering, aging, and ozone

At the same time, silicone rubber die-cut gaskets can be further customized and formulated to meet a range of different specifications. However, these gaskets shouldn’t be exposed to silicone fluids, solvents, or fuels. Common products that use silicone rubber include:

Die Cut Neoprene Rubber Gaskets and Seals 

As one of the first oil-resistant synthetic rubbers, die-cut neoprene rubber seals and gaskets are also referred to as polychloroprene rubber gaskets. No matter the name, neoprene rubber gaskets are moderately resistant to ozone, oxygen, UV, petroleum, and moderately high-temperature environments.

Neoprene is known as a general-purpose elastomer with a low compression set, good resilience, and good abrasion. At the same time, die-cut neoprene gaskets are resistant to flex cracking. 

With remarkable elasticity and flexibility, die-cut neoprene seals are able to snugly fit between gaps of components to form a fluid-tight seal. In general, there are four primary types of neoprene material used for gaskets:

  • Closed-cell neoprene materials
  • Cut open-cell neoprene materials
  • Diaphragm materials
  • Solid materials

In addition, each of these types of neoprene materials are offered in different densities, strengths, and other properties. 

Die Cut Polyurethane Rubber Gasket

Polyurethane is a compound that offers excellent tensile strength and abrasion resistance. In fact, die-cut polyurethane rubber gaskets and seals are recognized as the most abrasion-resistant and toughest of all. 

Polyurethane boasts the elasticity of rubber paired with the durability of strength. These exceptional qualities usually translate into an excellent performing rubber gasket material in all weather conditions. Polyurethane also offers excellent low and high-temperature performance: offers strong resistance to:

  • Temperatures as high as 230°F
  • Temperatures as low as -22°F

Ethylene Propylene Diene Monomer (EPDM) Die Cut Gasket

As a popular and versatile die-cut gasket, die-cut EPDM seals are extremely resistant to sunlight and high levels of heat. These gaskets can help stabilize color in the harshest of weather conditions, which makes them a highly sought-out material for outdoor applications.

EPDM rubber die cut gaskets are abrasion resistant and formulated to resist harsh chemicals, such as alkalis and acids. These die gut gaskets are ideal for applications involving petroleum and hydrocarbon oils, which usually cause other gasket materials to swell. 

Die Cut Nitrile or Buna-N Types of Rubber Gaskets

Nitrile — also known as Buna-N — is a very versatile rubber material. It's utilized in countless products and applications ranging from small engine carburetors to marine systems. In addition, die-cut nitrile rubber gaskets are widely used because of their ability to resist:

  • Butane
  • Silicone greases
  • Propane
  • Hydraulic fluids
  • Synthetic oils
  • Solvents
  • Water
  • Alcohols

Die Cut Styrene-Butadiene Rubber (SBR) Seals and Gaskets

As a copolymer of styrene and butadiene, red rubber or styrene-butadiene rubber (SBR) gaskets boast similar characteristics to natural rubber. Because of this, die-cut SBR gaskets are often substituted as a cost-effective alternative. 

Die-cut SBR seals can resist cold water, hot water, low-pressure steam, gas, and air. These gaskets also have excellent impact strength, remarkable abrasion resistance, and conform easily to uneven flange surfaces. 

In addition, SBR gaskets offer good resilience and high tensile strength. However, gaskets made from red rubber or SBR aren't best suited for use with solvents, oils, fuels, or hydraulic fluids.

Die Cut Viton Rubber Gaskets

The fluorocarbon elastomer Viton is a high-performing rubber compound renowned for its ability to resist extreme chemicals, concentrated acids, oils, aggressive fuels, and heat. In fact, Viton rubber gaskets can resist high temperatures of up to 500° F.

In addition to providing heat resistance, Viton is also resistant to mold, fungus, most mineral acids, alkalis, sun, weather, oxidation, and more.  At the same time, gaskets cut from Viton rubber gaskets offer resistance to compression sets over long periods of time at high temperatures.
