Gaskets & Seals by Aero - Custom Rubber Parts

Custom Rubber Seals & Gaskets for Any Industry

What is a rubber gasket & where is it used?

Custom Rubber Gaskets and Seals are common rubber products that are used in almost every business industry. Rubber gaskets form barriers between two objects. This helps prevent leaks or contamination of a container’s contents. The compressibility of rubber gaskets provides a sealing opportunity between two surfaces.

Is your sealing product a gasket or a seal? Stop by our blog to dig deeper into the difference between gaskets and seals.

Storage Tank & Piping Gaskets

Many of the industries listed above use storage and mixing tanks in their processes, which are sealed with rubber gaskets. Sealing applications often have material requirements for gaskets. These standards ensure the gaskets can easily withstand the chemicals and extreme temperatures they’re exposed to. For example, gaskets for potable water storage and distribution tanks may need to meet the NSF/ANSI 51 and/or NSF 61 standards.

At Aero, our sales engineers are familiar with common industry standards. They’ll work with you to help you find materials that are a good match for your application and your industry’s guidelines.

High Temperature & Low Temperature Applications

In some instances, your application will require gaskets that can endure high or low temperature conditions. Choosing the correct polymer, grade, and formulation is key to a lasting seal.

Certain elastomers have excellent resistance to either high heat or extreme cold. Sometimes, a material has a high tolerance for both. Those elastomers are ideal for exposure to an extended temperature range. For example, a silicone gasket used in industrial ovens may also work in a freezer or cooler within that facility.

Your sales engineer will discuss rubber compound options with you so you can make an informed decision about which elastomer will best meet your needs.

Gasket & Seal Materials

Some of the most popular materials for custom rubber seals and gaskets include:

Buna-N (Nitrile)

Buna-N, also called nitrile rubber, is a popular material option for oil-resistant seals and gaskets. Nitrile rubber provides superior resistance to alkalis, petroleum-based fluids, gasoline, hydraulic fluids, and acids. For this reason, Buna-N is the ideal choice for applications requiring solvent and oil resistance.

Buna-S (SBR)

This synthetic rubber material, sometimes referred to as “Red Rubber is popular due to its cost-effectiveness and its inherent benefits for abrasion resistance.

CSM — Chlorosulphinated Polyethylene (Formerly Hypalon®)

This material is extremely weather-resistant and can withstand UV light, ozone, and long-term sunlight. CSM offers great resistance to acids, most chemicals, oil, and abrasion. It also features low moisture absorption and good dielectric strength. These properties make it ideal for petrochemical, automotive, construction, and industrial applications.

EPDM

Made from ethylene and propylene, EPDM is a popular choice for outdoor use and water contact applications because of its resistance to UV, ozone, and sunlight exposure. This versatile material is preferred for outdoor applications due to its good weather aging properties, ability to stabilize color, and resistance to harsh weather conditions.

Fluorosilicone

Fluorosilicone has similar attributes to standard Silicone with added resistance to coolants, oils and petroleum-based chemicals. Like Silicone, Fluorosilicone can also withstand extreme (high and low) temperatures. Fluorosilicone is often specified for Aerospace applications.

Fluoroelastomer (FKM) / Chemours Viton Rubber (Brand)

FKM / Fluoroelastomers are high-performance materials with excellent resistance and high temperature range offering. A variety of FKM Compounds (A Type, B Type, LT, GLT, etc.) are developed for special / specification applications for higher and special chemical and temperature resistance.

Masticated Rubber

Masticated rubber is a compound manufactured utilizing recycled natural and/or synthetic rubbers. Masticated rubber offers superior hardness, durability, and tensile strength as well as high compressive strength and resistance to ozone and weathering. This material is well-suited for industrial applications with low economic targets. Common applications include the transportation industry, including – trucking, railroad, and mining.

Natural Rubber (Polyisoprene)

This natural material is derived from the milky sap or latex produced by the rubber plant. Natural rubber, or gum rubber, features excellent tensile strength, elongation, abrasion and tear resistance.. Natural rubber also features good flexing properties at low temperatures.

Neoprene

Neoprene is an excellent synthetic rubber material with very good / typical properties. Neoprene extremely versatile and is commonly used in a variety of environments due to its benefits for indoor and outdoor use, resistance to petroleum-based solvents and oils. Neoprene also features good resistance to aging, sunlight, ozone, and other weather elements. Neoprene has a good economic price-point, with options from economy grade to specification grade compounds.

Polyurethane

Polyurethane offers high tensile strength and elongation, is abrasion-resistant and extremely tough. Polyurethane can be run in wide variety of durometer/ hardness from OO scale, A Shore, and D Shore Hardness.

Silicone

Silicone also offers good tensile strength and elongation properties and excellent color and “gloss” for commercial and color match applications with an extended temperature range for low and high-temperature applications. Specification grade compounds are formulated for temperatures as low as -75°F, to temperatures that exceed 500°F.

Skirtboard — SBR/Natural Rubber Blend

Skirtboard is often used in applications that require strength, durability, and wear resistance. Skirtboard is often used in highly abrasive industrial applications, heavy construction, mining, etc

Synthetic Polyisoprene

This is the synthetic version of natural rubber. Synthetic Polyisoprene is often used in place of natural rubber where there may be concerns with allergic reaction to Latex Rubber Proteins. Like Latex Rubber, Synthetic Polyisoprene offers excellent tensile strength, abrasion and tear resistance.

Thermoplastic Rubber (TPR)

Thermoplastic rubber is a hybrid material with some elastomeric properties, with the added benefits of a plastic material. TPR’s are flexible materials that feature good shock absorption and resistance to ozone and weather. TPR’s can be used where a consistent finish, colors or color match are needed.

Viton®

This high-performance material features great compression set and permeability as well as resistance to concentrated acids, aggressive fuels, solvents, and oils.
