Japanese Patent JP2004518085
Kind Code:
A
Abstract:
The present invention relates to a pipe coupling (10) of the type where a pipe (12) is freely insertable into the coupling (14) and where a nut (44) causes engagement of a grip ring (38) and gasket (28) with the pipe (12) to provide a seal between the coupling (14) and the pipe (12) , and where within the coupling (14) there is disposed a stop (16) to indicate to a user inserting the pipe (12) freely that the pipe (12) has been inserted to its required location. The stop (16) is located at a position where there is room beyond the stop (16) for the pipe (12) to move into. Tightening of the nut (44) causes the pipe (12) to move further into the coupling beyond the stop(16) . This solves the problem of the pipe being inserted too deeply into the coupling and being deformed when the nut (44) is tightened further.
