1. Making a Crimp Connection
Cut PEX tubing end squarely. Remove any burrs.
Insert fitting into end of tubing until it stops. Slide crimp ring and position crimp ring 1/8″ to 1/4″ from the end of the tubing and over the ribs of the fitting.
Open the tool handle. Place the crimping end of the tool around the crimp ring and press the handles completely.
Check for proper crimp with the Go/ No-Go gauge.
2.Check for Proper Crimp
Measure the crimped ring with the GO-NO-GO gauge after the connection. The crimp ring should fit as the 1st image here:
Connection is complete
3.Remove the Crimp Ring
If the connection does not gauge, or it was done improperly, a crimp ring removal tool could be used to remove the crimp ring:
Cut off the section of PEX tubing with the fitting. Try to make the cut as close to the end of the fitting as possible without scratching it or damaging the cutter.
Rotate the piece 180 degrees and repeat Step 2. The PEX crimp ring will fully split in half, making it easy to remove it by hand.
The remaining piece of PEX tubing can now be easily removed, leaving an undamaged PEX fitting which can be used again.
