For my immersion wort chiller, I didn't use plastic tubing, I used a washing machine supply line cut in half. The supply line was made of heavy black rubber and has female garden hose fittings at each end allowing me to connect a garden hose at each end. The heavy black rubber stands up to the hot temperatures no problem, and I secured them to the copper tubing with a hose clamp. Depending on the size of your copper tubing, it can be a tight fit getting the hose over the copper, you can use a blowdryer or heat gun to heat the supply line, making it easier to stretch over the ends of the copper.
