Custom O-Ring seals

O-ring seals are one of the most common types of seals in use today, is a type of mechanical seal that consists of a thin, circular, elastomeric material compressed between two parts.

They are used in a wide range of applications, from automotive and industrial to aerospace. O-rings are used to seal different components together, preventing leakage and contamination between them.  The O-ring is compressed at high pressure, and forms a seal between the two parts.

The O-ring creates a watertight seal and protects the components from corrosion. For example, an O-ring can be used in a piston to prevent oil leakage from the engine. This type of seal is used in many different applications and industries including automotive, marine, military and aerospace industries, among others.

O-rings can be made from a variety of materials, including silicone, rubber and polyurethane. The material used for an O-ring will depend on what application it will be used for and the environment it must endure.

Custom O-ring seals can be made to any size or shape required by our customers, which makes them ideal for sealing pipes and other complex shapes. Because they are made to order with your specifications and dimensions, we can offer a wide range of sizes, as well as shapes that cannot be bought off the shelf at a local hardware store.

O-rings are typically made from rubber or metal and have an inner diameter (ID) and outer diameter (OD). The ID determines the size of the opening, while the OD determines how far into an opening the O-ring will go. The O-ring can be reused if properly cared for and lubricated with grease or oil before installation.

Why use custom O-ring seals?

The purpose of O-rings is usually to keep fluid or air from entering or exiting a space. They are an essential feature of many machines which are used in the completion of industrial processes. In some cases, the type of machinery and processes involved necessitates the use of custom O-ring seals so that they work effectively. Companies have to supply manufacturers with their requirements in order to obtain O-ring seals that are ideally suited to their needs.


Custom O-Ring sealsMost O-ring seals are used in a similar way. They are placed into a grove and then they are squeezed tight between two surfaces. This action means that they block the movement of air or fluid from one area to another. Depending on the type of machinery that a company is using, the O-rings seals utilized may need to be custom-made in order for them to work effectively.


The thing about a custom O-ring seal is that it’s made to be used in a specific set of circumstances. This means that there are millions of different O-ring seals available. They can be manufactured to be color coded for ease and safety of use. They can also be created to be food grade standards, for use in the food industry. In fact, more than 100 different compounds can be used to create O-ring seals for use in a variety of different industries. Customization of O-ring seals can include:

  • Colour
  • Type of packaging
  • Thickness
  • Size

Companies that require specific O-ring seals to be used during the completion of their processes need to approach a reputable manufacturer. They have to provide details of what they need so that the manufacturer can provide custom O-ring seals in line with their requirements.

Some common materials used in making custom O-rings include:

Silicone, nitrile rubber, Teflon® and Viton®, these materials can be used to make a wide range of O-ring seals.

Silicone is the most commonly used material in O-ring seals. Silicone has good chemical resistance, which makes it suitable for use in many different applications. Silicone is also very flexible and can be easily compressed into a variety of shapes. Silicone will not break down under normal working conditions and does not absorb moisture or contaminants.

Nitrile rubber is another common material used for making custom O-rings. Nitrile rubber has good abrasion resistance, high tensile strength, low temperature flexibility and excellent chemical resistance (including many acids). These properties make nitrile rubber an excellent choice for many uses where an O-ring seal would be required.

Teflon® (often just referred to as PTFE) is another common material used in making custom O-rings because of its extremely low friction coefficient and nonstick properties. Teflon® has excellent chemical resistance as well as minimal swelling at high temperatures (up to 480°F).

EPDM. Ethylene propylene diene monomer (EPDM) rubber offers excellent heat resistance, withstanding temperatures up to 280°C (536°F). This makes it appropriate for use in high temperature applications such as air conditioning systems or anywhere else where flexibility at low temperatures must be maintained while operating at higher temperatures.

The following are just a few benefits that you can enjoy when using custom O-ring seals:

O-ring seals are a type of mechanical seal used on rotating shafts or in other applications where a tight seal is needed to prevent leakage. They consist of an elastomeric ring, typically nitrile rubber or silicone rubber, that fits around the shaft and provides a close fit to prevent leakage between two parts. The two parts may be two sections of pipe joined by an elbow joint or two parts joined by a coupler or other fitting.

Product Protection: Custom O-ring seals are designed to protect your product from damage caused by moisture, dust or other contaminants. This can help prevent leaks and other problems that can cause your product to fail prematurely.

Increased Durability: Custom o-rings will help protect your product from damage caused by wear and tear during normal use. This will increase the overall durability and lifespan of your products, which can save you money in the long run.

Improved Hygiene: Custom O-ring seals are ideal for hygienic applications where it is important to prevent cross-contamination between different products or between food preparation areas and customer seating areas. They can be used with food packaging products or in industrial settings that require cleanliness and sterility such as hospitals and laboratories.

They are easy to use, and they come in a variety of sizes and shapes: This makes them very versatile and allows them to be used in a wide range of applications. You won’t have to worry about having multiple sizes on hand when using these types of seals because they will fit most of the products that you need to seal.

Custom O-ring seals are long lasting: This means they will last longer than other types of seals that you may have tried before. This is great if you intend on using the same product over and over again because they won’t wear out as quickly as some other types of seals might do over time.

These types of seals are made from high quality materials that are durable enough to withstand any sort of abuse that might occur during transport or storage for long periods of time without breaking down or becoming damaged in any way.

Custom O-Ring seals are one of the most popular products that we manufacture

We can make a custom O-Ring seal in any shape and size, from a small diameter to as large as you need it. Custom O-Ring seals are typically made from silicone rubber or nitrile rubber, but we can also make them from other materials such as Buna N or EPDM rubber.

One of the main benefits of using a custom O-Ring seal is that it allows you to create a seal with an exact fit for your application. There is no need to worry about having the wrong size seal or having to modify an existing product to fit your needs. We can also offer you different durometers (hardness) so that you can choose exactly how soft or stiff you want your seal to be.

Another benefit of using a custom O-Ring seal is that they can be molded into any shape or size needed for your application. This means that you don’t have to modify an existing product – instead, we can create something specifically made for your needs!
