To install a WEATHERHEAD Ermeto Flareless fitting, cut the tube square, deburr, and insert it fully into the fitting. Tighten the nut until the ferrule bites into the tube, then follow the manufacturer's torque specification. Avoid over-tightening to prevent tube collapse. Always use proper tools for leak-free assembly.
