'X' Series Casing
Amko flush-coupled casing has a box thread at both ends and is connected by a pin to pin
coupling. This allows replacement of couplings when pin threads become worn or damaged.
Each length of casing is supplied with one coupling. Lefthand threaded casing can be supplied
on request.
