If necessary, their gas tightness must also be checked, when using highly volatile gases.

The chamber and the slide are not shut off from each other in a gas-tight manner.

Said chamber is linked with the outlet channel in a gas-tight manner.

Joint seals are provided that allow the production of a gas-tight seal upon completion of assembly of the airbag inflator.

The discharge vessel (2, 22) gas-tightly retains an ionizable fill comprising sodium.

A method for obtaining gas-sealing around rock chambers or rock storage chambers.

The advantage of using metal bellows is that they are gas-tight in so far as no leak arises over time.

The first reactant diffuses as such through the substrate or proceeds after gastight sealing as ion through the deposited layer in order to react with the second reactant and to produce a gastight layer.

The coating film (2) perfectly covers the base material (1) and imparts gas tightness to the sheet for thermal pressing (20).

The seal member (66) has a first seal unit (66a) and a second seal unit (66b) which are mutually layered for sealing the fuel gas.

When the gasket is compressed between the cylinder head and engine block, the stopper ensures that the compression beads remain elastically biased against one another and maintain a gas-tight seal.

  The gastight container has a gastight property.

When a tubular body containing a synthetic resin material of a high gas-barrier quality is heated and fused, heat may decompose and foam the material.

Heat is transferred from the rotor (18) to the cylinder head (10) by a split ring seal (34), which seal also provides gas sealing between the rotor (18) and the valve casing.
