ERIKS - ERIKS O-ring Technical Handbook
O-rings are bi-directional seals, circular in shape and cross section. O-rings are generally made of an elastomeric material, but may be made of other materials such as PTFE or metal. This hand-book deals entirely with elastomeric O-rings and PTFE encapsu-lated elastomeric O-rings. An O-ring seals through the deformation of the seal material by

Sinek's theory is that communicating 'Why' taps into the part of the listener's brain that influences behavior. This is why the Golden Circle model is considered such an influential theory of leadership. At an organizational level, communicating you're 'Why' is the basis of a strong value proposition that will differentiate your brand from others.

Stresses and Deformation of Compressed Elastomeric O-Ring ...
Elastomeric O-ring seals have a broad range of service conditions that make the O-ring ideal for static and dynamic sealing functions. Its ability to seal on relatively rough surface finishes offers one of the economical solutions to sealing problems. Elastomeric O-rings are capable of undergoing large deformations under compression. Hence ...
O-ring theory of economic development - Wikipedia
The O-ring theory of economic development is a model of economic development put forward by Michael Kremer in 1993, which proposes that tasks of production must be executed proficiently together in order for any of them to be of high value. The key feature of this model is positive assortative matching, whereby people with similar skill levels work together.

O-ring Seal Design Best Practices - HpAEC
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

UNDERSTANDING MECHANICAL SEALS
O-ring must move when this compensation takes place, it is pushed forward by the components of the seal and by stuffing box pressure. If the seal is configured with a "dynamic" O-ring of this type the seal is called a pusher type. Illustrated here is a Type RS-81, a common pusher seal. As the seal
