5. Release the trigger, remove

the head from the piping,

rotate it ⅛ turn and slide the

head back into the piping.

Continue expanding and

rotating until the piping and

ring are snug against the

shoulder on the expander

head. See Table 2-2.

Important! Rotating the

tool between expansions

will provide smooth, even

expansion of the piping.

Failure to rotate the tool will

cause deep grooves in the

piping which can result in

potential leak paths.

6. After the nal expansion,

immediately remove the

tool and insert the tting.

Ensure the piping and ring

seat against the shoulder of

the tting.
