Is a seal the same as a logo?

Logos are a shortcut that represent an organization’s promise to its stakeholders. Logos are a vessel into which you can pour meaning, whereas seals have a default meaning.

How much should an O-ring stick out?

To provide an effective seal, the O-ring’s inside diameter (I.D.) must be smaller than the piston groove diameter, so that the O-ring is slightly stretched, fitting snugly in the groove. This stretch should be between 1%-5% with 2% as the ideal in most applications. A stretch greater than 5% is not recommended.

How deep should a groove be for an O-ring?

How are static seals applied to the gland?

In a static seal application their is little to no relative motion between the parts of the gland that come in contact with the O-ring. Static seals are commonly categorized according to the direction of the squeeze that is applied to the O-ring. The two basic directions of squeeze are axial and radial.

Which is the best seal for a dovetail gland?

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.

What should be included in the design of a gland?

Numerous factors go into the appropriate design of a gland/groove including but not limited to static or dynamic applications, pressure conditions, fluid characteristics being sealed, and tolerances of both the o-ring and groove. The o-ring cross-section in your design will determine all your subsequent dimensions and specifications.
