A seal between these parts prevents escape of gases. The seal includes a trough fixed to one of the parts and receiving the other. The trough contains a body of a non-coking non-flammable liquid, preferably silicone, into which the other part extends. Optionally the trough may also contain a gasket of a closed cell sponge elastomer or a layer of granular material.
