Nothing shrinks copper tube.
Tube feet are a series of small tubular projections that can be find on all echinoderms, including the star fish. By pumping fluids in and out of these tubes, hydraulic pressure is created that can be used to grip onto a surface or circulate materials around the feet. In star fish, tube feet are often used as suction cups to keep a grip on the environment and prevent being swept away by undersea tides.
The starfish takes in water into the tube feet, (expanding the tube feet) the water is then forced out of the tube feet, (contracting the tube feet) making it able to grab onto the object.
No , these are present in echinoderms .
In rubber electrons cannot freely move among atoms as in copper.

tube feet are most common in echinoderms. this is a phylum which includes animals such as sea stars and sea urchins. echinoderms control much of the movement of their tube feet using their water vascular system.
Copper tube is a favorite choice for plumbing, heating, cooling and other systems. Copper tube is most often used for supply of hot and cold tap water as refrigerant line in HVAC systems. There are two basic types of copper tube, soft copper and rigid copper. Copper tubing is joined using flare connection, compression connection, or solder. Copper offers a high level of corrosion resistance, but is becoming very costly. alliedallcityinc.com

One of the functions for tube feet are for movment, and also so they can pry open their clams.
Tube feet are structures that operate like a suction cup.
Grooved method? Threads on the end of the pipe? There is no tube or pipe in copper with threads. You can end a copper pipe with a connection that is threaded to accept steel pipe.
Echinoderms use their tube feet by using their water vascular system, so their tube feet are basically controlled by a water pressure system. Tube feet are adapted to a different uses in the groups of echinoderms by being able to use their tube feet to attach to objects as well as for protection and the gaining their nutrients.
tube feet can suck anything, but moves slow.
Yes echinoderms have that internal hydrological system that lets them run their tube feet.
