• Check tool calibration before starting a job.
• Check each crimp with the GO/NO GO gauge and calibrate
tools as necessary.
• Examine tools frequently for loose or missing parts, wear
and damage.
• DO NOT use tools that are in need of repair.
• A tool with worn parts may not calibrate.
• Lubricate all tool pivot points regularly with light oil.
Wipe off excess oil before using tools.
• DO NOT use crimp tools for other purposes.
• DO NOT throw or drop tools.
• DO NOT use a crimp gauge which is bent or damaged.
BESTPEX brass insert fittings are designed to be installed into the ends of PEX tubing. A permanent, sealed connection is made by properly crimping a black-copper ring around the tubing, which presses the
tubing into the spaces between the ribs of the inserted fitting.
BESTPEX black-colored copper rings are marked "PEX" and/or SDR9 and are annealed for ease of crimping. The rings must be located over the ribs of the inserted fitting and crimped into place with a crimping tool.
DO NOT USE:
• Copper-colored rings designed for polybutylene systems with pex tubing
• Fittings which have defects such as cuts, gouges, or abrasions
• Hose clamps or solvent cements
• Fittings that are not marked "PEX", or SDR9 and/or F1807
• Lubricants of any kind on the tubing or fittings
CRIMPING INSTRUCTIONS
FOLLOW THESE INSTRUCTIONS CAREFULLY TO ENSURE PROPER CRIMP CONNECTIONS
1. Cut tubing squarely without burrs.
2. Slide the correct size of black copper crimp ring over the end of the tubing.
3. Insert fitting into pipe to shoulder or tube stop • position crimp ring 1/8" - 1/4" from end of tubing.
4. The crimp ring must be attached straight.
Center tool jaws over ring
Close handles completely
5. Check crimps with gauge. To check: push the gauge down straight onto the crimped ring.
NEVER slide gauge over ring from the side.Do not attempt to gauge the crimp at the jaw overlap area. This area
is indicated by a slight removal of the blacking treatment revealing the underlying copper.
6. For rings checked with GO/NO GO gauge: You have a good crimp if the GO gauge fits the ring and the NO GO
does not. You have a bad crimp if the GO gauge does not fit the ring or the NO GO gauge does fit.
Insert fittings with a bad crimp should be cut out of the tubing
