<p>A tube coupling having a male body (12), a female body (10) for receiving at least a portion of the male body (12) and at least one peripheral member made from a relatively compressible plastic material molded into a groove within either the relatively rigid male or female body (10, 12). The peripheral member (60, 62) is disposed to become compressed against a surface of the mating body to form a liquid seal. At least two peripheral members (60, 62) disposed in grooves (52, 54) in a tubular shaped end portion of the male body (12) are made of a compressible plastic and serve as liquid sealing and locking means. The female body (10) comprises a receiving end portion (20) with a tapered interior (22) adapted to receive the male tubular end portion (12). As the tubular end portion (50) is inserted into the receiving end portion (20), one of the peripheral members (60, 62) engages the tapered interior surface (22) and becomes compressed there against as the tubular end portion (50) is further inserted. As the tubular end portion (50) is fully inserted a second peripheral member (56) seats itself in a groove (32) in the interior surface of the receiving end portion (20) acting to lock the male (12) and female (10) bodies together. The relatively compressible peripheral members (60, 62) are formed in grooves (52, 54) in the relatively rigid male (12) or female (10) body by insert molding or by simultaneous injection molding of two dissimilar plastics.</p> |
