The single-blade crimp slip-out

Pipe crimpers must be held completely perpendicular (90^°) to the pipe axis to form stable mechanical corrugated ridges. Drive the blades a full 11/2 inches deep into the metal rim. Overlap your previous corrugated indentation by at least two blade slots.

Stop if

• The pipe is backing out of the elbow because your crimps are shallow and crooked. Hold the 5-blade tool straight at ninety degrees to the pipe wall, and bite a full inch and a half deep all the way around the ring.

Watch out

• Do not force the tool through the problem or substitute the wrong tool just to keep moving.

Check

• Check the raw edge, pocket, or overlap before locking the joint.
• Seat the tool fully and square before applying force.
• Use a full controlled stroke when the tool needs a mechanical lock.
• Test the fit before sending the piece overhead.
• Remake or re-edge the part if the lock will not hold.
