Instructions for Installing ASTM F1960
Expansion fittings for Watts PERT Tubing
IS-WR-ASTM-F1960-PERT-Fitting
Read this Manual BEFORE using this equipment.
Failure to read and follow all safety and use information
can result in death, serious personal injury, property dam-
age, or damage to the equipment.
Keep this Manual for future reference.
3. Using an ASTM F1960 tube expander,
expand sleeve fully. Repeat expansions,
rotating expander 1/8-turn between
expansions. Note: To limit the amount of
time for tube compression onto fitting in
cold environments, expand the tube/sleeve
slowly and only enough to fully insert the
fitting. Keeping sleeves warm will speed
retraction and inhibit unequal expansion.
Use Milwaukee Tools M12 or M18 Cordless
ProPex® Expansion Tool for expanding
tubing. Milwaukee tools are sold through
Milwaukee distributors.
5. The installation is complete with a visibly
secure connection. Remove defective
connections. Test completed joint.
1. Cut tube at 90-degrees. Do not crush OD of
tubing with cutters.
Hint: Slightly rotate cutter during
blade engagement.
2. Install PEX sleeve onto OD of tubing.
4. Insert fitting into expanded tube and
sleeve. Assure proper expansion so that
fitting is touching tube and sleeve. Hold fitting
in place until tube/sleeve memory constrict
annularly around the fitting.
• F1960 compression rings are PEX.
• Compression is made by placing a compression ring onto tube,
expanding PERT tube and ring, inserting a full-flow fitting, and
holding in place until tube/ring memory secures the connection.
• Handling requirements are included within the
Fitting/Ring Limitation Section.
• Fittings are reusable if barb is undamaged.
• F1960 Expansion Fittings are not suitable for RadiantPEX
or Rad tubing.
