Separable plug-in pipe coupling - for use with rubber pipes conveying gases or liquids coupling members have interlocking teeth

摘要

The coupling consists of two similar members with axial holes running into transverse holes respectively. The member houses a rubber or plastic seal which fits flush with the mating surface. The members are provided with inter-locking teeth so that when they are pushed together a pressure tight seal is achieved. The tubular members are provided with O-ring seats fitting in grooves between collars and are held in place by the retaining members which fit in the transverse holes. The bulbous sections of the tubular members provide a firm grip for the attachment of the rubber pipes.
