ABSTRACT:
A connector for a metal ribbed pipe comprises a ribbed pipe, an adapter having a protrusion and connecting with a fluid receiving apparatus, a plurality of inserts having a recess contacting to the protrusion and having a collar opposite to the recess, a sleeve fitted on the collar, and a nut for assembling the sleeve with the adapter. Due to the close contact between the protrusion and the recess, the connecting end of the ribbed pipe flares in to achieve a tight seal.
