Materials Testing, 1997
In this article, the author discusses the importance of selecting the proper materials for various seal designs. For every seal application there is an optimal pair of rubbing materials that provides the longest life and lowest operating cost. This rubbing pair must be selected from among scores of seal nose materials and an equally large number of ...

Performance and Acceptance of Respirator Facial Seals
Ergonomics, 1970Three respirator full face masks with different paripheral seal designs (flat, inner flap, and pneumatic) were modified to permit study of the facial seal component. Twelve subjects participated in the study. Each subject completed a three-hour test session on each mask.

Design Parameters of Brush Seals and Their Impact on Seal Performance
Volume 6: Oil and Gas Applications; Concentrating Solar Power Plants; Steam Turbines; Wind Energy, 2012Brush seals, which were originally designed for gas turbine applications, have been successfully applied to large-scale steam turbines within the past decade. From gas turbine applications, the fundamental behavior and designing levers are known. However, the application of brush seals to a steam turbine is still a challenge.

A Model for Static Sealing Performance of End Face Seals
Tribology Transactions, 1994The effect of face loading, surface roughness and material properties on the static sealing performance of mechanical face seals is analyzed. The analysis combines the problems of contact and flow between two rough surfaces. The results are compared with available experimental data and are found to be reasonable.

Sealing Performance and Wear Mechanism of PTFE Oil Seal
2009Modified PTFE oil seal is studied: non-linear finite element model of sealing interface is established to simulate the distribution of contact stress and the grinding condition. The friction and wear properties of PTFE composite are investigated in different loads under dry and oil-lubricated conditions.

The wettability of sealing materials and its effect on sealing performance: Part I
Sealing Technology, 2016Wetting influences the sealing mechanisms of rotary shaft lip seals and rod seals. This article, published in two parts, shows how to determine the surface free energy of sealing materials, especially elastomers. Wetting parameters and their influence on sealing operation are explained, and a hypothesis is proposed to connect wetting phenomena with ...

Sealing performance prediction software
Sealing Technology, 1997Abstract Elastomer seals are widely used throughout industry and seal failure can be very expensive, in both financial and safety terms. One failure mode causing major concern is progressive degradation. It is generally of a long term nature and its extent and consequences in service can be particularly difficult to predict.

Influence of Sludge on Seal Performance
SAE Technical Paper Series, 1998<div class="htmlview paragraph">There is a case of leakage caused by improper lip contact due to the build-up of sludge on the lip area. Sludge, which is mainly carbide, is generated typically from aged oil under high temperature (150°C or more) conditions. However, it can also be generated in driving systems such as transfers.
