Abstract
A pipe coupling including an externally threaded body and an internally threaded nut. The nut's outer end includes an outwardly converging internal circular surface and a spacer is co-operable with the nut and body. The coupling further includes an O-ring and a deformable gripping member. The gripping member has an internal surface with barbs extending radially inwardly therefrom. An end of a pipe is insertable through said gripping member, spacer and O-ring into the body. Tightening of the nut causes axial movement of said spacer, sealing engagement of said O-ring to the body and pipe, and radially inward deformation of said gripping member such that said barbs clamp the pipe. The diameter of the O-ring is greater than that of the spacer at points where it is secured before tightening of the nut and less than that of the spacer when the nut has been tightened.
