Desired tubes of the plurality of tubes are connected via a plurality of return tubes.

The deterrent apparatus is suitable for use on medical tubing or veterinary tubing, for example, to deter animals from chewing or biting at the tubing.

Difference between ERW Pipes, SSAW Pipes and LSAW Pipes

The rigid pipes (41) and the hoses (42a) are coupled by the joints (43).

When the pipe union is tensioned, the teeth engage the pipe surface and non-positively interconnect the pipes.

The pipes of the present invention may be in the form of flexible pipes.

The second longitudinal pipes (7) are provided in flow connection with the end pipes (5, 6).

To thread the pipes, one pipe rotates about the joint axis.

To thread the pipes, one pipe rotates about the joint axis.
