Crimped plastic pipe union - has plastic body with metal bush forming annular space for pipe end

摘要

The union forms a coupling to a plastic pipe, having a plastic body with a bore accommodating the plastic pipe end. A rigid metal bush (2) fixed to the body (1) extends into the bore so that its surface is clear of the inner surface of the latter, forming an annular rcess for the plastic pipe end. After insertion of the pipe end a strong elastic metal ring (5) round the body is crimped against it, to clamp it and the plastic pipe against the bush and form a sealed joint. The bush can protrude beyond the body, to aid pressing the pipe end home.
