Soil ingestion by elastomeric seals
Studies of elastomeric seal failure have until recently focused on the erosion of the sealing interface. This has limited the improvements in seal life to the application of wear-resistant materials. The present work shows that three stages of particle ingestion precede seal erosion, and that seals …

Mechanics of swellable elastomeric seals
… thesis investigates the mechanics of swellable elastomeric seals for the purpose of hydraulic fracturing in oil and gas applications. The first component of the thesis is the development of a laboratory-scale apparatus for the visualization of swellable seals in situ up to the point of leakage. …

Lifetime Prediction and Durability of Elastomeric Seals for Fuel Cell Applications
… membrane (PEM) fuel cell (FC) stacks require elastomeric gaskets for each cell to keep the reactant gases within their respective regions[1]. If any gasket degrades or fails, the reactant gases can leak or mix with each other directly during operation or standby, affecting the overall …

The effect of hydrocarbon exposure and temperature on the behaviour of elastomeric seals
Synthetic jet fuels have been proposed as alternatives to petroleum Jet A-1. Compatibility issues, however, are of concern; specifically the interaction of synthetic fuels with polymeric materials which are commonly used to seal fuel systems. This is because of differences between the composition …

Improving the heat, fire, and melt resistance of elastomeric seals on military gas masks
… soldier will have to rely on a gas mask with an elastomeric seal that is not resistant to fire or melting. If a soldier is traveling in a vehicle with his or her gas mask on and gets hit by an IED, facial and eye bum injuries are very possible. New material must be found that can help prevent …

Effects of a Surface Engineered Metallic Coating on Elastomeric Valve Stem Seal Leakage
… expense in leak detection and repair programs. Elastomeric O-rings can be used as valve stem seals, and O-ring manufacturers recommend lubrication of elastomeric seals to prevent damage and to assure proper sealing. In this research, a metallic coating was applied as a lubricant using a vacuum …

A Study of Durability for Elastomeric Fuel Cell Seals and an Examination of Confinement Effects in Elastomeric Joints
… in series to achieve the desired voltage levels. Elastomeric gaskets are commonly used between each cell to insure that the reactant gases are isolated; any failure of a fuel cell gasket can cause the reactants to mix, which may lead to failure of the fuel cell. An investigation of the durability …
