Connect PEX with ASTM F2080 Expansion Fittings and Compression Sleeves
With brass fittings and compression sleeves, F2080 is the Rolls-Royce of PEX fitting systems.
When making a PEX connection using ASTM F2080 expansion fittings, start by cutting the PEX tubing square. Then slip a compression sleeve onto the tubing, pushing it back far enough so that it doesn’t interfere with the expansion. Make sure the beveled edge of the compression sleeve is toward the fitting. Use a Comboloc expansion tool to expand the tubing twice, rotating the tool slightly between the two expansions. After the expansion is complete, immediately insert your fitting. Using the other end of the Comboloc tool, slip the jaws onto the fitting and behind the collar, and squeeze the handles to pull the sleeve over the fitting and tubing.
