▶ 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 󶈵ts the ring and the NO GO does not. A crimp
is unacceptable if the GO gauge does not 󶈵t the ring or the
NO GO gauge does 󶈵t. An incorrect crimp must be cut out of the
tubing and replaced.
Crimp dimensions can be veri󶈵ed with the provided
Go/No-Go gauge.
