Yes. Rigid plastic PVC (Polyvinyl-Chloride) tubing can be joined to copper using "grip fittings." Each side of a grip fitting contains a narrow grip ring and a plastic compression ring (or rubber O-ring) that forms the seal.
Useful Tips:

• Use penetrating oil to help loosen corroded mounting nuts.
• Use a hacksaw for cutting steel or plastic pipe.
• Use a basin wrench for those hard to reach areas.
• Use a tubing cutter to make straight, smooth cuts in plastic and copper tubing.
• Wrap thread seal tape clockwise around threaded joints to ensure a tight seal.
