O-Ring Seal Design. For O-ring design, it is best to follow the manufacturer's guidelines and select the most appropriate O-ring and corresponding groove size. They already have tables of standard seal sizes and related gland dimensions for specific O-ring types and maximum working pressure.

O-rings and seals in dynamic radial applications should consider the following; temperatures, motion or vibration, squeeze, stretch, friction and types of friction. Datwyler Sealing Solutions USA Inc, provides the basic o-ring gland design for theses applications.

The O-ring is the most widely used seal in history because of its simplicity, low cost, ease of installation and small space requirements. O-rings are designed for both static and dynamic applications. A properly designed O-ring groove allows the O-ring to be squeezed diametrically out-of-round even before the application of pressure.

Reciprocating O-Ring Design Guide . Click image above to see design charge, table and guide 5-2 . O-rings are best when used on short-stroke, relatively small diameter applications. Millions of O-rings however, are used very successfully in reciprocating hydraulic, pneumatic, and other fluid systems which employ long stroke, large diameter seals. If designed properly, an O-ring seal will give ...

Dynamic O-rings. FRICTION - the higher the durometer hardness (above 70 Shore A) the greater the friction. This is due to the fact that the compressive force, at the same squeeze, is greater than with softer compounds. Compound swell decreases with hardness and may increase the friction. The lower the operating temperature, the harder the seal ...

Static Radial Applications Common Fixed Seal : Axial The O ring cross section is squeezed axially in the groove similar to a flat gasket: Static Axial Applications Face Seals : …

The tendency of an O-ring to return to its original shape when the cross section is deflected is the basic reason why O-rings make excellent seals. The squeeze or rate of compression is a major consideration in O-ring seal design. Elastomers may take up the stack-up of tolerances of the unit and its memory maintains a sealed condition.

A great start is ARP1231, "Gland Design, Elastomeric O-Ring Seals, General Considerations." This specification covers many aspects to consider in O-ring seal design. Aerospace recommended Practice ARP1232, ARP1233 and ARP1234 cover O-ring gland seal design for the AS568 series O-rings.

This two piece piston seal design comes made with a heat-stabilized, thermoplasti step-cut ring along with a profiled NBR energizer. This product offers extreme strength and resistance to extrusion, a very high resistance to abrasion, and ease of installation thanks to the step cut design and chamfered edges.

The use of back-up rings or increased seal durometer may also be necessary to prevent O-ring extrusion. For more information on the effects of pressure, seeIllustration 5.1in Section 5 . Squeeze. Listed inTable A1, under "Gland Design" at the beginning of this section, are the recommended squeeze values for O-rings employed in reciprocating ...

Quad-Rings® Brand and O-Rings seals are routinely used for face seal applications, which can be either static or dynamic applications. General Considerations The seal should be selected and the groove should be designed so the seal is always positioned against the side of …

Gland Design Types Dynamic Radial O-ring Gland Design. In dynamic radial applications the O-ring is squeezed radially, and experiences intermittent or continuous reciprocating motion. Dynamic radial O-rings are subjected to friction between the sealing surfaces. O-rings and seals in dynamic radial applications should consider: Temperature

Design Guide 5-2a: Gland Dimensions for Industrial Recipro-cating O-Ring Seals 5.31.2 O-Ring Glands for Industrial Reciprocating Seals Design Chart 5-2 provides a reasonable basis for calculating reciprocating O-ring seal glands. Design Table 5-2, which follows it, contains recommended gland dimensions for the standard AS568A O-ring sizes. The ...

Face seals are a simple o-ring gland design and most adaptable to imprecise geometries, but require precise and solid attachment and checking over time. Radial seals can be used in dynamic and static applications, the best example is of a piston and cylinder.

Gland Design, Elastomeric O-Ring Seals, Dynamic Radial, 1500 psi Max. ARP1233A. This document establishes standard gland design criteria and dimensions for dynamic radial O-ring seal applications and provides recommendations for modifying these glands in special applications. There are no provisions in this document for anti-extrusion devices.

;The hub dynamic seal of propeller hub adopts an O-ring seal,and its actual clearance directly changes the compression rate,which has an impact on the sealing performance. The actual clearance of the seal face of the hub was analyzed from the design and working point of view.

In radial seals, the gland is defined by the Bore Diameter on the outside radius, the Groove Diameter on the inside radius, and the Groove Width in the axial direction (see schematic).. Inner Diameter. In order for the O-Ring to fit snugly in the groove, it is desirable to circumferentially stretch the O-Ring slightly.

Reciprocating type seals and their gland design can be subdivided into hydraulic and pneumatic applications. 2.4.1 Dynamic seal – hydraulic. O-rings are used in piston and piston rod seals. They provide good results over a wide range of pressures and sometimes also are used with back-up rings. The average deformation of the cross-section is ...

Global O-Ring and Seal has developed o-ring groove design and gland dimension guidelines. These are intended for use in basic design consideration and to understand the core principles involved in o-ring gland/groove design. Numerous factors go into the appropriate design of a gland/groove including but not limited to static or dynamic ...

WARNING: Gland Depth x Groove Width (area of the gland) must be larger than the cross section area of the o-ring (Pi x R^2).Otherwise many bad things will happen to your design. Make sure the squeeze % is sufficiently high enough to seal, but low enough to allow dynamic movements.

Face Seal Glands for Basic Applications. Static o-ring face seals, used for a wide variety of applications, come in many shapes and forms. Whether you need bolted flanges or removable lids, this o-ring face seal groove design guide will help you choose the right o-ring for your application.

1.0 O-RING SEALS – THEORY AND DESIGN PRACTICES Theory: An o-ring seal consists of an o-ring and a properly designed gland which applies a predictable deformation to the o-ring. The gland is basically a groove dimensioned to a certain height "H" and width "W" (Figure 1) to allow a fixed compression of the o-ring when the gland flanges ...

Dynamic Sealing . Dynamic sealing is considerably more involved than static sealing. Not only does a seal have to prevent the flow of some medium, like in static sealing, but it also has to be able to perform that task while in motion and with frictional forces to consider.
