A seal is created, compressing the o-ring cross-section between two mating hardware components. As the two mating surfaces come together, the compression exerted on the seal deforms the o-ring, creating the initial squeeze pressure. When the sealed fluid exerts higher pressure, the o-ring is forced to the low-pressure gland wall and away from
s, the O-ring is completely confined and pressure deformed (crushed) within a triangular gland made by machining a 45° angle on the male cover. Squeezed at an angle to the O-ring's axis, crush seals are used in such simple applications as the one depicted in Illustration 4.4 .
O-Ring Size - Gland Design . O-Ring Failure Description: The O-Ring does not perform as expected without visual damage. Contributing Factors: Incorrect groove or gland design. Improper o-ring sizing. Hardware damage or misalignment. Suggested Solutions: Underperforming O-Ring seals can typically be improved by optimizing the O-Ring size or gland design for the specific application conditions.

Visual indications: The cross-section of the O-ring becomes less circular with flattened surfaces that have taken the shape of the groove/gland. The O-ring has taken on a permanent 'set' meaning it is unable to recover to its original shape after removal of deforming stresses.
Seal Types & Gland Design 13 In this application, O-ring squeeze is primarily axial in direction (valve operation exerts force on top and bottom seal surfaces). To avoid tearing or nicking, the use of O-ring lubrication is recommended while installing the O-ring into the dovetail gland. Because of
The O-ring's outside diameter (O.D.) should be at least equal to or larger than the rod gland diameter to give interference on the O-ring's O.D. The O-ring's O.D. should not exceed 3% of the rod gland diameter for O-rings with an I.D. greater than 250 mm, or 5% for …
Seal Types & Gland Design *Note: The current revision of the Standard is "C" but it changes periodically. **O-Ring seal sizes not listed are not recommended for axial seals because the seal ID after installation becomes too small for practical use.

An O-ring is a donut-shaped ring made of molded, flexible material with a round cross-section that can be either solid or hollow. These pliable rings are designed to be inserted into a groove, referred to as a gland, where they predictably re-form themselves to completely fill the …
With a similar appearance to extrusion, gland overfill failure mode also has the unique, "tails" of O-ring material. The difference is the tails extend out from both corners of the groove, and, if significant, you may see the round O-ring cross section now resembles a square.
approximate fractional dimensions of the O-ring. Prior to the common use of dial calipers many people called out a 1 inch by 1-1/4 rt = O-ring, this was a dash -214 O-ring. They used to also use these fractional dimensions as the gland size. So, the nominal size is in …

When designing o-ring glands, by far the two best resources out there are put out by Parker and Apple Rubber. For standard design applications you cannot beat the Parker O-ring Handbook, that goes into extreme depth on dimensions and applications.For applications that you cannot get the standard gland dimensions on, or that you do not need 5,000+ psi of sealing reliability use the Apple Rubber ...

O-ring failure is often caused by a combination of factors including improper installation, allowing for too much or too little compression in the gland design, inadequate lubrication, abrasion, or using an O-ring seal that is the incorrect size or type of elastomer for your application.
DESIGN DIMENSIONS FOR O-RING INSTALLATION O-rings are normally used as seals in several ways, and dimensions of the groove or gland will also vary with the cross section of the ring, the type of operation, and the amount of pressure used in the system. These dimensions will also be different if the O-ring is sealing a liquid which has a low volume
Welcome to our O-ring Groove Design section. Here you will find an O-ring groove design guide to help you with your O-ring gland dimensions. Through our extensive research we believe that these O-ring groove dimensions and fit details will provide the optimum O-ring compression squeeze for your seal to prevent O-ring leaks.

Please contact the local ERIKS repre-sentative if an application does not clearly fall into these design parameters. Static Applications There are five types of static O-ring applications: • Flange seal • Radial seal • Dovetail seal • Boss seal ...
2. Find the recommended O-ring size and gland dimensions in the appropriate design table in Static O-Ring Sealing or Dynamic O-Ring Sealing, Sections IV and V, respectively. 3. For industrial use, order the O-ring by the Parker compound number followed by the size number. Example: N0674-70 2-325. 4.

Calculate the O-Ring groove dimensions. Using the table above, determine the maximum recommended gland depth for your application. Then, calculate the O-Ring groove diameter as follows: a. For a rod (shaft) seal: O-Ring Max Groove Diameter = Min Shaft Diameter + (2 x Recommended Gland Depth) b. For a bore (piston) seal:

An O ring consists of an O ring mounted in the gland so that the O ring's cross-section is compressed slightly when the gland is assembled. Quad ring seals This is a modified square type cross-section made up from homogeneous synthetic rubber.
General Engineering Menu | O-Rings Suppliers Molded O-Rings Services. The following chart gives typical gland dimensions for common o-ring sizes. Please consult with your o-ring manufacturer for custom or application specific requirements. To use this document, first identify if you have an internal or external pressure gland requirement.
Any type of foreign contaminant interferes with the O-rings ability to squeeze into the groove or gland. To ensure that the seal is being maintained, it is important to inspect, clean, and lubricate an O-ring.
