1. The tubing should be cut squarely and evenly without
2
burrs. Uneven, jagged or irregular cuts will produce
unsatisfactory connections.
2. The diagram shows a correctly cut tube compared
with an incorrectly cut tube.
3. Slide the crimp ring onto the tubing and insert the
fitting into the pipe to the shoulder or tube stop.
4. Position the ring ⅛" to ¼" from the end of the tubing.
5. The ring must be attached straight. Center the
crimping tool jaws exactly over the ring. Keep
the tool at 90° and close the handles completely.

DO NOT CRIMP TWICE.
6. When checking crimp connections with a
caliper (GO/NO GO gauge), push the gauge
STRAIGHT DOWN over the crimped ring. NEVER slide
the gauge in from the side. Do not attempt to gauge
the crimp at the jaw overlap area. The overlap area
is indicated by a slight removal of the blackening
treatment. A crimp is acceptable if the GO gauge
fits the ring and the NO GO does not. A crimp is
unacceptable if the GO gauge does not fit the ring or
the NO GO gauge does fit. An incorrect crimp must

be cut out of the tubing and replaced. If you check the
crimp connections with a micrometer or caliper, use
the dimensions shown in the chart above.
CRIMP DIAMETER DIMENSIONS
Crimp outside diameters should fall within these dimensions
when measured with a micrometer or caliper.
