PIPE JOINT

摘要

The present invention relates to a pipe coupling, at least a portion of which corresponding to a tip end position of a pipe inserted into the coupling is formed of a transparent resin, , through which an operator can visually confirm whether or not the pipe is fully inserted into the coupling. A pipe coupling comprises a coupling base body; an inner cylinder that extends from the coupling substrate and is fitted into an inner circumference of the pipe; an O-ring that is fitted onto the outer surface of the inner cylinder; a transparent resin collar that corresponds to a tip end position of the pipe when the pipe is fully inserted into the inner cylinder, is fixed to the coupling base body, and through which the tip end of the pipe can be visually observed; a pipe holding member disposed at the tip end of the resin collar to hold the pipe; an pipe release ring disposed at the tip end of the resin collar; and a sleeve that is attached to the resin collar so as to cover at least a portion of the resin collar, the pipe holding member and the pipe release ring.
