SYMPTOMS POSSIBLE CAUSES WHAT TO DO
Coupling crimp diameter above
or below specification.
Crimp dies, die rings damaged,
worn, or faulty.
Visually inspect all wear
surfaces for raised metal dents
or gouges. Replace damaged
die sets and die rings. Worn or
faulty die sets will crimp above
or below specifications by the
same amount with and without
the die ring. Replace worn or
faulty die sets.
Die cavity in base plate worn or
faulty.
Check crimp diameter of several
different sizes of die sets with
both the silver and black die
rings. If all crimp dimeters
are out of specification by the
same amount, the die cavity in
the base plate may be out of
specification. Contact Technical
Services Department at
(440) 943-5700 for repair.
Lubricate the die cavity in base
plate frequently to prevent wear.
