O-Rings from Allied Metric Seals & Fasteners, Inc.

Our o-ring kit varies; we have over ten kits with various o rings sizes for you. These will help you find a suitable o-ring or seal for your operations. Plus, we create custom kits that meet your specifications and requirements.

O-rings are an essential seal used for static or dynamic applications. They seal between two objects, such as pipes, cylinders, tubes, and pistons. The goal of using these is to block the leakage of gas or liquids. Furthermore, they’re made of different pliable materials for excellent sealing and longer life.

What are the Common Materials Used in Making O-Rings?

Different types of materials have been used over the years to meet the needs of various industries. The most common materials always have the same characteristics and benefits, primarily because these seals are used in harsh and stressful conditions.

Some of these materials are as follows:

Types of O-Rings Available

Our size chart consists of different types. There are two functional designs available, which are static and dynamic—the difference between the two lies in the purpose of how they will be used.

Static O-Rings

Static o-rings are used as gaskets or seals in sealing applications that don’t move. They are perfect for pipes, hydraulic fittings, and other stationary components. Once the connection between the services is made, the application is static.

Dynamic O-Rings

Dynamic o-rings are used to seal two components when there’s motion. The materials required for making these types are more complicated since they must be more challenging, resistant, and stronger to prevent friction or abrasion.

The two types of dynamic o-rings:

  • Rotary seal: Rotary seals are used when the turning shaft protrudes from the inner diameter. Some factors to be considered during this application are friction, squeeze, type of shaft, and seal stretch. And for these applications, the shafts must be made of rigid metal and be non-abrasive.
  • Reciprocating seal: It’s the most common form of dynamic o-ring usage, and you need to consider its thermal cycling, squeeze, stretch, and pressure shock. And for these applications, the surfaces must be finished since they don’t retain their lubrication.

Custom O-Ring Kits for Various Projects

At Allied Metrics Seals & Fasteners, Inc., we can design custom o-ring kits if our customers can’t find what they need in the o ring sizes charts. We have a team of experts in this field who can help you create and design the perfect seals for your projects. Rest assured that we can meet your expectations while delivering a successful project.
