When pipes, boilers, fuel tanks and more need to be joined together, what’s the best way to prevent liquid or gas from leaking?
Contact us to discuss your requirements of custom round rubber gasket. Our experienced sales team can help you identify the options that best suit your needs.
The answer: a gasket.
At Breiner Innovative, we make a lot of gaskets. Our parts make their way around the world, helping manufacturers, mechanical contractors and more maintain the integrity of their equipment.
Many different non-metallic materials can be used in gasket manufacturing, with each presenting their own unique advantages and abilities under different circumstances. The following examples are some of the most common and versatile non-metallic gasket materials we use.
It’s a popular choice for a reason — natural rubber is a good all-around, general-purpose gasket material. While it shouldn’t be used with fuels, oils or solvents, natural rubber is incredibly water resistant and works very well with metal surfaces. Natural rubber is great to use with water pumps and pipes for its good shock and vibration resistance qualities.
Natural gum rubber is a gasket material that makes great insulation for water pumps and pipes.
Flexibility, weather resistance, and electrical insulation properties make silicone rubber a very popular choice for gasket materials. Silicone maintains high performance at extreme temperatures, remaining functional between -60°F and more than +400°F. Its versatility makes silicone rubber ideal for a wide variety of applications, including pharmaceutical and food processing environments.
Silicone rubber is a gasket material that’s versatile to many industries, from medical to food-processing.
Typically used in marine and other outdoor applications, neoprene rubber has the ability to resist moderate levels of sunlight, ozone, and other weather elements along with greases, fats, and oils. Neoprene rubber can also be used in refrigerant applications. This polymer can withstand a wide range of temperatures from -31°F to 250°F.
Neoprene rubber is a great material to make gaskets that resist a wide range of solvents and temperatures.
Neoprene sponge is a gasket material that’s well suited for industrial settings using fuel, oil, and other chemicals. As a synthetic rubber with both open and closed cell forms, it’s cellular nature is great at repelling dust, water, and moisture while still keeping it’s superior absorption, insulation and compressive properties. Most closed cell neoprene sponges can meet UL 94HF-1 flame ratings.
Neoprene sponge gasket material is perfectly suited for insulating caustic fuels, oils, and industrial chemicals.

Oil and solvent-resistant, cork is a popular gasket material for manufacturers due to its high compressibility and flexibility. Since it comes from the bark of the cork oak tree, cork is a naturally renewable and sustainable gasket material that’s highly impermeable, buoyant, elastic and fire retardant. It’s typically used for gaskets in oil and fuel pumps or around electrical gear.
Cork gaskets are not only renewable resources, but also quite impermeable to fuels and fire.
Introduced to fill the void left when asbestos was discovered to be a dangerous material, compressed non-asbestos gaskets combine great strength with a high resistance to heat, water, gases, oils, fuels, and chemicals. These types of gaskets are at home in hard-to-seal applications, such as in the presence of steam and sustained high temperatures.
Non-asbestos makes a safe, strong, and highly liquid-resistant gasket material for manufacturers.
There is no one solution to any particular application. Some gasket materials perform admirably in a variety of situations, while some excel or lack in other specific environments. No matter what you require out of your next batch of gaskets, our experts at Breiner Innovative can help you choose the perfect material for your needs.

The purpose of a gasket is to protect machinery from adverse weather conditions. By keeping water, dust, dirt and debris out of machinery, they allow the products to deliver optimal performance, minimising risk of damage. There are two common materials used for gaskets: silicone and neoprene. In this article, PIF explores the merits of both materials.
It is important for gaskets to be flexible, durable and versatile and, as silicone and neoprene both exhibit these characteristics, it makes them the obvious choices. However, deciding which material to use should be a careful consideration. There are a number of factors to take into account when deciding to purchase a silicone or neoprene gasket and PIF has examined the benefits of both.
Silicone gaskets come in solid, foam and sponge varieties – making it an extremely versatile option. It is a resilient material that boasts high temperature stability and does not react with many substances, rendering it generally inert. Silicone is an excellent choice for gaskets because it forms a tight seal and repels water. Plus, its ability to withstand temperature extremes makes it superior to many other types of rubber.
Solid silicone can be used with metal closures and requires good closure force, while the closed cell structure of silicone sponge and foam make them suitable for environmental sealing applications where lower closure forces are relevant. Suitable for use in either high or low temperature environments, Silicone sponge’s firmness is measured in psi or density, with two to five psi or 250kg/m3 considered soft and 14 to 20 psi or 650kg/m3 considered firm. Silicone foam with a closed cell structure is therefore suited for an environmental enclosure.
Silicone has good compression set performance, its advantages include:
Synthetic rubber neoprene is the DuPont trade name for chloroprene, a versatile synthetic rubber. It displays good resilience and resistance to UV and ozone damage. This durable material can withstand temperature highs of up to 120°C, and lows of down to -40°C. Neoprene has good chemical stability, and good general resistance to oils and petroleum-based fuels.
The advantages of neoprene include:
Neoprene and silicone have similar characteristics and uses. However, they are subtly different in properties and characteristics. When deciding which gasket material to specify, it is important to weigh up their advantages and disadvantages when compared to the particular demands of your application. Neither material is better than the other overall per se, it entirely depends on your specific needs.
Silicone is the best choice for applications that will be subjected to extreme temperature ranges or weather exposure, while neoprene is better for applications that require oil-resistant and tear-resistant properties. In essence, you would be well advised to speak to a Martin’s Rubber expert for an honest assessment of which particular material will best suit your application.
