Coupling piece for liquid or gas connection in solar installation using corrugated sleeve with sealing mantle at either end

摘要

The coupling piece (10) has a flexible corrugated sleeve (13) extending between a pair of pipe connections for respective components of a solar installation and fitted with a silicon rubber sealing mantle (11,11a) at either end, secured via one or more internal radial annular projections (15) fitting between adjacent sleeve corrugations, with external radial annular projections (14) cooperating with the inside wall of the liquid or gas connection. An independent claim for a coupling system is also included.
