Spliced O-Rings come in a variety of styles. Some are hot vulcanized while others are formed by the Hydra Pak process. Some are referred to as Haltec O-Rings and have unique features.

Types of Spliced O-Rings

Spliced O-Rings can be manufactured from a variety of materials. Synthetic rubber is used, offering good heat, oil, and flame resistance. Some other materials include PTFE, aramid fiber, and vegetable fiber. Splicing the O-ring involves pressure, adhesive, and a special splicing jig. This process is a simple and efficient way to produce custom-size O-rings in large quantities, without expensive tooling costs.

Vulcanization is another method for creating spliced O-rings. In this process, an uncured compound is used to create a durable seal using time, pressure, and heat. The mating ends of a cord material are placed in a special splicing jig, where they are vulcanized with heat. After the process is complete, the O-rings are removed from the jig and cleaned to remove any excess rubber.

In addition to choosing the appropriate material for the application, it is important to consider the application temperature and operating conditions. Once you've determined these factors, you can proceed to make a decision about what O-ring to use. If possible, conduct some tests in the field to ensure compatibility.

Vulcanized O-rings are a good option for more complex applications. These products are made from synthetic rubber or silicone and provide excellent heat and oil resistance. They can also be used in nonstandard grooves or designs. For larger parts, these O-rings are inexpensive and can be custom-molded in various materials.

Splicing rubber products using hot splicing is an efficient way to join different types of materials. This method requires a temperature-sensitive adhesive, which activates the rubber-based glue. The result is an attractive and reliable joint. However, following the proper dwell time is important to ensure optimal performance.

Vulcanized O-Rings are often used in static sealing applications, where the seal does not need to interact with moving parts. These types of O-Rings are easy to manufacture, inexpensive, and require no special tooling. They're also useful for prototypes but are not recommended for dynamic applications. In some cases, imperfections in the joint reduce the effectiveness of the seal.

Custom O-rings are a popular option for OEMs. With a customized O-ring, an OEM can avoid common mistakes made during assembly. The company also guarantees fast turnaround, which is important for keeping a schedule. In addition, custom spliced O-Rings are often cheaper than traditional O-Rings.


Spliced O-Rings are an economical alternative to standard O-rings. They are created from a cord material that has been extruded and vulcanized to the desired size. Ace Seal offers seamless spliced Metric and English O-Rings, along with splicing kits. The company also offers Parker Back-Up Rings, Quad-Rings, and other O-rings and seals.

Spliced O-Rings have many advantages, and are especially suitable for static applications. They are less likely to break when compared to vulcanized O-rings. These O-rings are not recommended for dynamic applications, however, because of the process of vulcanization, which involves a mixture of heat and adhesive. Once the process is complete, excess rubber is removed from the finished O-ring.

Spliced O-rings are primarily made of two materials, a vulcanized cord stock, and an extruded cord stock. The vulcanized material provides strength and flexibility and is available in any diameter. They are also available in metric and AS568A standards and can be ordered in virtually any size and shape.

The materials used to make spliced O-rings should be of the highest quality. FKM is the material of choice for sealing applications, but other materials, such as ULTRA or HI Fluor, are more flexible and able to withstand extreme pressures and temperatures. The spliced O-ring is an integral part of the system, so it is important to choose the right materials for the job.

O-Ring materials must withstand high and low temperatures. High temperatures can burn or decompose materials, and low temperatures may cause them to fail to seal. Chemical attacks can degrade materials, causing them to swell and crack. They may also become brittle and break when exposed to low-viscosity fluid.

An O-Ring should pass a twist and tug test as well as a lock-down test. This will ensure the O-Ring is not broken or stretched at the joint. This means that the O-Ring should be able to withstand the stress and pressure from the mating parts.

High-temperature O-rings often require tangential compression to compensate for the Gow-Joule effect. For these applications, spliced and vulcanized O-rings are an excellent option. They will also likely save you money compared to traditional O-rings.

Profiles Hollow or Solid

A hollow or solid spliced O-Ring profile is a great choice for a variety of sealing applications. These profiles have a similar design to an O-ring but are capable of higher compression. This compressibility allows them to compensate for high hardware tolerances. The hollow core of these profiles also prevents the seal material from rupturing.

Hollow O-Rings are available in a variety of materials and cross-sections. They can also be made to fit nearly any groove. These profiles can be manufactured using state-of-the-art hot vulcanization techniques. These processes allow for the production of hollow or solid spliced O-Rings for a wide range of applications.

Vulcanized O-rings are commonly used in the Pharmaceutical Industry and filtration industries. However, they can be used anywhere a flange or lid needs to be sealed. They are especially useful for sealing lids on rectangular containers, provided that they are installed in the appropriate groove.

Cross Sections CSD and Tolerances

O-rings serve a variety of needs. These flexible seals are available in various materials including silicone, PTFE, and Buna-N. They are electrically insulated, corrosion-resistant, and salt-resistant. Their sizes can be customized according to your needs. They can be purchased in metric and JIS dimensions, and are available in a wide range of cross sections.

Vulcanized O-Rings are commonly used in gasket and storage tank applications. They can be used anywhere where flanges need to be sealed. They can also be used on rectangular containers. These vulcanized O-Rings can be used on various kinds of seals, including gaskets, seals, and valves.

Standard O-rings come in metric and imperial sizes. The former is widely used worldwide and follows the International Standard ISO 3601-1:2002. The latter is based on two series of measurements - the G series and the A series. The G series includes sizes for general-purpose and aerospace applications.

Tolerances are important when selecting O-Rings. A good machine will be able to hold a variety of Rings, including spliced O-Ring. These rings should be tested for pinholes and cracks, as they will result in premature failure.
