Custom Gasket Manufacturing

  • Custom Fabricated Gaskets | Custom Rubber Gaskets | Rubber Gaskets

Gaskets are components fabricated from various types of flat sheet of soft material including cork, rubber, silicone, foam, felt, plastic, vegetable fiber, and more. Unlike seals which are used to form a seal between two rotating components to prevent the leakage of fluid, gaskets are used on static components to act as spacers or to control or dampen noise and vibration, or to prevent leaks.


What Are the Different Types of Gaskets and What Are They Used For?

Gaskets are used by various industries and for applications including piping and vehicle components.  Rubber gasket materials are typically soft and flexible and chosen based on application requirements such as resistance to pressure, temperature and chemicals. Gaskets are made from various types of rubber but can also be manufactured using cork, felt, plant fibers, or other materials.

Some of the common types of gaskets include:

Flange Gaskets 

Used to join two sections of pipe to prevent leaks. The two most common types of flange gaskets are ring-type and full-face.

Spiral Wound Gaskets

Precision gaskets that provide resistance to corrosion and used for high-temperature and high-pressure applications.

Gaskets Used for Function

Includes gaskets that are designed to perform specific functions such as resistance to temperature, chemicals or pressure.

Vehicle Gaskets

Used in components for cars, trucks, planes, trains, and boats

Gaskets are also categorized by material type including:

Grafoil Gaskets

Fabricated from flexible graphite material used for applications requiring resistance to corrosion, chemicals, and heat or fire.

Compressed Non-Asbestos Gaskets

Used for high temperature applications and in pumps and valves.

Rubber Gaskets

Includes gaskets made from various materials including silicone, EDPM and open-cell or closed-cell sponge. They provide temperature resistance, toughness and flexibility and are used for pipes, automotive applications, heat exchangers, and mechanical applications.

Cork and Vegetable Fiber Gaskets

Provide heat tolerance and are commonly used for applications requiring resistance to water, grease, oil or gasoline.

Our Custom Gasket Manufacturing Processes

Our cutting capabilities for custom fabricated gaskets include Water Jet Cut, Laser Cut, and Die Cut processes. Ace Seal utilizes ultra-high-speed rotary die-cutting equipment to produce high-quality, high-volume, close tolerance parts. All die cut gaskets are available with permanent or semi-permanent pressure sensitive adhesive.

Waterjet Cut Custom Gaskets

Water jet cutting is a process that utilizes water and abrasives which are pressurized to create a beam of fluid that will cut through almost any material. Abrasives in the solution ensure the cut is swift and smooth with minimal edge burring and no material distortion. Water jet cutting is suitable for large production runs and is an efficient way to manufacture rubber gaskets with intricate shapes.

Die Cut Custom Gaskets

Die cutting involves using semi-automatic or automatic presses for die and kiss cutting from sheets of rubber or roll stock. Steel die cutting involves using a cylindrical die to perforate or cut gaskets from sheets or rolls of rubber. The die cuts through the rubber material and adhesive backing to create individual gaskets and is a suitable process for short and large production runs.

The kiss cutting process makes light impression cuts in the rubber gasket material but leaves the adhesive backing intact. When the surrounding waste material is removed, the gaskets are left adhered to the long paper sheets. This method allows sheets of gaskets to be rolled for easy “peel and stick” dispensing and is an excellent solution for high volume gasket production.

Molded Rubber Gaskets

Molded gaskets can be manufactured using either injection molding or compression molding. Injection molding is ideal for high-volume gasket production and involves injecting melted rubber or plastic resin into a mold. This process has a fast production time and works well for smaller gaskets and intricate shapes. It can cost more than compression molding but is still considered a cost-effective process because of its high efficiency.

Compression molding is ideal for small or medium-sized production runs and involves compressing heated rubber into a mold using a press. It costs less than injection molding and works well for high durometer materials and for producing large, small or intricate gaskets.

What Materials Are Used to Make Custom Gaskets?

Custom fabricated gaskets can be manufactured in endless material choices that are chosen based on requirements including temperature tolerance, chemical compatibility, environmental conditions, and the life expectancy of the gasket material. Ace Seal offers various material options ranging from felt to flexible graphite to meet the needs of a wide range of applications.
