ABSTRACT:
Check valve adapted for being mounted in and sealed to a tube made of elastomeric material. The valve has an elongated outer hollow body made of thermoplastic material, said body being adapted to be telescoped for a substantial portion of its length into the end of the elastomeric tube. The valve is retained in the tube and sealed thereto by a formation comprising a flange having a first radially outwardly directed transverse portion integrally connected to the main part of the body of the valve and a second sleeve-like part coaxial of the main portion of the valve body, spaced from the outer surface thereof, and integrally connected at one of its ends to the outer edge of the first portion of the flange, the main portion of the body of the valve and the second portion of the flange forming an annular space adapted to receive the end of the tube therewithin, the outer free end of the second part of the flange being adapted to be deformed by being heated and thrust radially inwardly so as to secure the tube and seal it to the valve body.
