Abstract:

A compression type coupling 10 for pipes has a body member 12 and a fastener member 14 and a ferrule 16 wherein the fastener member has a perpendicular shoulder 36 with respect to a longitudinal axis of the pipe 18 and abuts a squared shoulder section 42 of the ferrule to prevent the ferrule from being squeezed out of the compression coupling 10. The ferrule has outwardly radially extending flanges to retain it within the fastener member. The ferrule also has radially inwardly extending teeth that bite into the pipe to prevent the pipe from backing out. The ferrule also has an axially inner section 40 with notches 62 formed therein. The end 40 is deformed by a camming surface 28 on the body 12 to crimp the pipe 18 as the fastener member 14 is secured to the body member 12. The axially inner section 40 forms a right angled shoulder that abuts the pipe and prevents the pipe from being easily pulled out of the coupling.
