An O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, forming a seal at the interface.. The O-ring may be used in static applications or in dynamic applications where there is relative motion between the ...

13. O-ring Assembling Conditions • For problem free assembly of O-rings it is important that metal parts are rounded and free from sharp areas. Never force the O-ring over sharp threads, keyways, slots and other sharp edges. • Do not use sharp tools, use an O-ring assembling aid to avoid damage.

The recommended amount of stretch S is between 1% to 5%, with 2% as the preferred stretch value. By stretching the O-Ring, we ensure that the O-Ring will stay in the groove and will not fall out or otherwise twist in some unpredictable manner during assembly. The O-Ring is compressed in the radial direction when seated in the gland.

Preliminary O-ring Design Considerations: An o-ring is a simple and versatile ring shaped packing or sealing device. Having a circular cross section that functions as a seal, in both static and dynamic applications, by being compressed between the mating surfaces comprising the walls of the gland, in which it is installed.

To facilitate assembly, the diameter of the O-ring groove is usually selected somewhat larger than the diameter of the O-ring. This keeps the O-ring in the groove during assembly. Elastomer rings can safely be stretched in length by 5 %. The maximum stretch is dependent on the material and the operating conditions.

The groove must be properly sized to allow for the maximum expansion of the rubber compound, otherwise, the assembly will develop very high stresses. When enough force is applied, the o-ring will move toward the low-pressure side until it contacts the side of the groove. Additional pressure or force will deform the o-ring toward the extrusion gap.

Verify all O-rings are installed and discharge ports are off center toward the inlet block. Slide end block onto tie rods. Lay base plate assembly on a flat surface. Use "Recommendations for Torque Accuracy" to tighten the tie rod nuts to the correct torque listed in Appendix A. Mount the divider valves with O-rings onto the base plate.

Application of O-rings in rotary motions In a rotating application a shaft contin-uously rotates in the inside diameter of the O-ring, causing friction and heat. Because rubber is a poor conductor of heat, the O-ring can loose its proper-ties. To minimize or reduce wear, the following could be done; however consult the local ERIKS representative:

The efficiency and the duration of the O-Rings' seal are connected to the preservation of the chemical and physical characteristics. An incorrect job or an incorrect assembly, such an example could provoke superficial scratching to the ring, could be the cause of decay of the capacity of the seal and of the accelerated ageing of the compound.

elements; O-ring and gland — constitute the classic O-ring seal assembly. 1.3 Advantages of O-rings • They seal over a wide range of pressure, temperature and tolerance. • Ease of service, no smearing or retightening. • No critical torque on tightening, therefore unlikely to cause structural damage.

Temporary rubber assembly lubricants can: 1. Reduce Installation Force: A thin film of lubricant applied to a part fills in any gaps, holes, or spaces between two separate surfaces, allowing them to slide across each other. By reducing the surface tension between the two surfaces, rubber parts can slide into place easily, providing a tight fit. 2.

Figures 1 and 2 show finite element models of what happens when O-rings are installed with 40 percent and 25 percent squeeze, respectively. The models depict O-ring pinch damage during assembly in a male (piston-type) O-ring gland. At the 40 percent level, pinching is difficult to avoid while pinching is eliminated at the 25 percent level.

A reused PTFE O-Ring may look and perform similarly to a standard rubber O-Ring suffering from extreme compression set. But unlike rubber, this compression set occurs after only one use. More often, PTFE O-Rings are found in flange gasket type applications where the seal will remain static and undisturbed until the next service interval.

Overall, it's best to avoid using excess force while installing O-rings. Using an assembly lubricant helps ensure that many of the above problems are avoided. O-ring Lubricants. Using a lubricant for O-ring assembly can prevent tears, twisting, pinching, cutting and abrasion of the rubber.
