To install a PARKER single-ferrule compression fitting like the 8-4 HBZ-B, cut tubing squarely, deburr the end, and slide the nut and ferrule onto the tube. Insert the tube fully into the fitting body, then tighten the nut by hand plus a specified number of turns (typically 1-1/4 turns) using a wrench. Always follow PARKER's published torque guidelines for CPI™ fittings.
