O-Rings
o-rings
Butt Splice – typically used for endless gaskets where there is limited or no stress at the splice
Bevel splice – if the cross sectional area does not allow for butt splice this may be used as an alternative providing more surface area for bonding
Step splice – used when a bond of maximum strength is required, yet permitting nominal deformation under compression or tension when used as a static seal
Corner Splice – used to produce gaskets of special configurations, they work well where the bond is not under strain and is a static application< /Asset/oring91.jpg

O-Ring Configurator
The O-ring is the most widely used seal in the industry. It is easy to install, may be used as a double-acting seal and can seal pressures of up to 800 PSI. With pressures over 800 to 2,000 PSI, backup rings should be considered for higher pressures. The o-ring is typically used as a reciprocating seal, not for rotating shaft applications (Lip seals should be used for rotating shafts). O-rings are typically sized by their inside diameter and cross section, and are further specified by the type of compound used. For O-ring sizes other than standard sizes, specify the actual dimensions desired for the inside diameter (I.D.) and the cross section (W). There may be a tooling charge for such non-standards. /Asset/oring71.jpg Standard O-Rings (AS568)
Standard O-Rings are available in 369 sizes as set up by the Aerospace Standard 568 published by the Society of Automotive Engineers. These sizes are designated by dash numbers shown on the 568 DASH Chart and are standardized by imperial dimensions. Standard O-Rings are specified by their inside diameter and cross section width. AS568 is the most commonly used standard in the U.S. for aerospace, automotive and general industrial applications.

Metric O-Rings are employed in specialized applications and, like the name suggests, are standardized by metric dimensions. With a wide variety of sizes available, Metric O-Rings fill in the gaps left by the standardized AS568 o-ring chart. Metric O-Ring sizing is determined by the o-ring's inside diameter and cross section width.

Japanese Industrial Standard O-Rings are another popular classification system used around the globe. Published by the Japanese Standard Association, these o-rings are also categorized using the metric system. JIS O-Rings are used in many different fields, but typically are implemented in Japan's semiconductor, automotive and machine tool industries.For more information, please see: Comparison Properties Chart, PTFE Encapsulated O-rings, Material Shelf Life, and O-ring Groove Design Chart. /Asset/oring71.jpg BS O-Rings
British Standard O-Rings are very similar to Standard O-Rings in the fact that they are both standardized imperically. The British Standard however, incorporates some extended sizes in the 1/4" nominal cross section group for an even broader application range. British Standard O-Rings serve a variety of industries including aerospace, paint, food, and chemical transport.

Vulcanized O-Rings (or Spliced O-Rings) are great for a custom design or a unique size that is not included on the standard charts. We have a wide variety of o-ring cord materials that can be spliced and vulcanized to your specifications. Butt, Bevel, Corner, Step or Molded Splices are available depending on your project needs.Rubber extrusions may be converted to endless gaskets with a variety of vulcanization methods. For more information, please see: Comparison Properties Chart, PTFE Encapsulated O-rings, Material Shelf Life, and O-ring Groove Design Chart. Vulcanization is a process which uses heat, rubber adhesive, pressure and time to chemically bond the two ends together. There are a variety of joints which can be bonded. Round cord or irregular profiles may be vulcanized to endless gaskets. Applications such as window frame gaskets, door gaskets, filter housing gaskets and lid gaskets. The uses are as unlimited as your imagination will allow.Butt Splice – typically used for endless gaskets where there is limited or no stress at the splice
Bevel splice – if the cross sectional area does not allow for butt splice this may be used as an alternative providing more surface area for bonding

O-Ring Kits
O-Ring Kits are ideal when your exact project specifications are not known. O-Ring Kits offer a wide variety of sizes, in the compound you select, in order to save time and increase productivity. We have standard kits ready to order, and we also can custom make o-ring kits to fit your requirements.For more information, please see: Comparison Properties Chart, PTFE Encapsulated O-rings, Material Shelf Life, and O-ring Groove Design Chart. /Asset/oring9.jpg
Back-Up O-Rings
Back Up O-Rings are implemented when your primary seal is subject to high temperatures or pressures, or if an excessive extrusion gap is presented in the application. They serve to provide extra strength to the seal and prevent your primary seal from being damaged. Whenever possible two back-up rings should be placed, one on each side of the primary seal.For more information, please see: Comparison Properties Chart, PTFE Encapsulated O-rings, Material Shelf Life, and O-ring Groove Design Chart. /Asset/oring11.jpg
AS568 PTFE O-Rings - 900 Series
