Custom O-Ring Seals
O-ring seals are mechanical gaskets with a round cross-section. They are made from elastomer materials and used in pumps, cylinders, and other fluid applications to form a leak-proof seal between two parts. O-rings are installed into a machined or molded groove on a part surface; when the two parts are joined, it compresses the O-ring and deforms the cross-section, creating a tight seal.

If you are unsure of which material is best for your application, view our Properties Comparison Chart for information about some of the most commonly used O-ring materials or contact us for assistance.
Our Elastomers Include:
O-ring products can be used across a broad range of operating temperatures and in low- or high-pressure applications. There are several advantages to using O-rings, including:
- Compact design
- Easy to install and maintain
- Reusable (depending on material and application)
When appropriately used, O-rings do not require adjusting and have a long usable life. Factors that contribute to O-ring failure include improper installation, inadequate lubrication, abrasion, using the incorrect size or elastomer, or allowing for too much or too little compression in the gland design. You can prevent these any other issues by selecting an O-ring in the right size and durometer, and in a material that is compatible with your application temperature, fluid/chemical type, and sealing pressure.
Our team has the expertise to help you select the right O-ring product design, size, and elastomer for your application. Learn more about our inventory of O-ring products below or contact us to discuss your unique sealing requirements.

Spliced & Vulcanized O-Rings
Spliced O-ring seals are an excellent alternative for applications where a standard O-ring cannot be used. Our spliced O-rings are made from an extruded O-ring cord that is vulcanized to form a seamless joint. We produce spliced and vulcanized O-ring seals in English or Metric sizes, including custom IDs, and in several elastomers.
EMI-Shielded O-Rings & Seals
Combine the benefits of sealing and shielding with our EMI-shielded O-ring products, including seals, O-rings, and molded parts. These seals are made with conductive, particle-filled elastomers and ideal for electronics applications.
We provide O-ring cord in bulk or spliced and vulcanized into custom O-ring seals. Options include standard round cord, quad/x-ring cord, and square cord.
Our O-ring seal kits include a convenient plastic storage case filled with the most popular O-ring sizes in the industry. We provide O-ring kits in virtually any material.
