Step 3 – Now slide a crimp/clamp ring over the tubing and add the end part of the pipe fitting into the pipe so the pipe end touches the shoulder of the PEX fitting. Any hydronic application with water temperatures at or below this value is perfectly applicable for the product. Addressing expansion and contraction. Installing a bend support will prevent this, and it will also protect the pipe from abrasion.
