An o-ring is a doughnut-shaped object, or torus. The opposite sides of an o-ring are squeezed between the walls of the cavity or "gland" into which the o-ring is installed. The resulting zero clearance within the gland provides an effective seal, blocking the flow of liquids or gases through the gland's internal passage.

O-ring Gland Design If friction is excessive a variety of possible solutions exist: • Select a different O-ring hardness. • Select a different O-ring material with improved coefficient of friction. • Increase the groove depth. • Consider the use of an alternate design of seal. • Viton®has much lower friction than NBR or EPDM or Silicone.

For the extrusion gaps, SKF recommends machining the fits according to the following tolerance classes: F8and H9 for diameters up to 120 mm. F7and H8 for diameters larger than 120 mm. Diagrams 1 to 3 provide guideline values for the maximum extrusion gap in relation to the operating pressure for standard O-rings without back-up ring ( diagram 1

O-Ring Groove (Gland) Design Guide. For rotary O-rings: a compression ratio of 0-10%. For reciprocating O-rings: a compression ratio of 10-20%. For a static male to mating interface: a compression ratio of 18-25%. For a face seal: a compression ratio of 20-30%.

As important as the o'ring seal itself is the groove that the o'ring seats into. The groove must be designed to accommodate not just the o'ring size, but also 

In order for the O-Ring to fit snugly in the groove, it is desirable to circumferentially stretch the O-Ring slightly. The recommended amount of stretch S

O-Rings continue to be the most widely utilized sealing product. While the 'Donut' shaped profile has by and large been kept intact since their inception, 

O-Ring Basics; Seal Thinking™ Elastomer seals are unlike any other materials that design engineers confront. Metal or plastic parts, for instance, are probably failing if visibly distorted. But, an o-ring MUST be deformed to function properly. In fact, an o-ring that is not squeezed and stretched in its application is the wrong o-ring.

Jan 30,  · What is an O-Ring? An O-Ring is a donut shaped round ring also referred to as a torus. While O-Rings can be made from plastic materials, or even metal, this reference guide will focus exclusively on rubber, or elastomeric, materials and their unique design and performance considerations. O-Rings are designed to prevent the passage of a liquid

Static Applications There are five types of static O-ring applications: • Flange seal • Radial seal • Dovetail seal • Boss seal
