include a deformable portion interconnected to a vapour barrier portion by way of a mechanical or adhesive interlocking connection. This deformable portion can be made from an elastomeric material. The vapour barrier portion can be formed from a wide variety of materials that inhibit permeation of t

are coupled by lodging the spiral into a channel of the gasket -creating the assembly. The gasket is evenly coupled in the outer circumference of the spiral, in which a cushion plate (made from a resilient material) is installed. Breakage of the gasket during assembly of the outer pipe is effectivel
A simple and versatile pneumatically-operated two-layer rotary valve is described for simultaneous introduction of samples and diversion of analytical streams in flow injection analysis. Examples of applications include valve configurations with time-controlled sample volume and with loop-controlled
or more of what are termed stress-control grooves on its surface. These grooves enable material to deform laterally and increase the contact stress between seal and counter-surface at the corners of the groove. The design is intended to preserve sealing integrity over wide temperature excursions exp
