Installation Guide
1. Slide the correct slot 
on the gauge around
the crimped ring.
2. If the ring does not t 
into the slot at all, then 
the crimp is a “No-Go”. 
Adjust the crimping force 
on the tool and re-crimp 
the ring.
3. If the ring slides into the 
slot and stops in the 
“Go” range, then the 
crimp is good.
4. If the ring slides all the 
way into the slot, 
then the crimp ring is 
compressed too small 
and is a “No-Go”. 
Remove the ring and 
adjust the crimping force 
on the tool.
