F1807 Installation
3. Install PEX tting into tube end.
5. Compress tool perpendicular to
tubing run. Compress only once.
Remove defective connections. Use
a gauge to assure a proper joint. 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 Crimp Ring onto OD
of tubing.
4. Position ring over sealing barbs
of the tting. The ring should be
positioned approximately 1/8" to
1/4" from the end of the tube.
F1807 ttings can be made from various listed materials.
See ASTM standard for acceptable brass alloys. Assure
your tting is made from a listed material.
F1807 systems use a copper crimp ring to compress
around a tting.
Connection is made by positioning a crimp ring over a
tting’s sealing barbs and compressing it into position.
Fittings are reusable if barbs remain undamaged.
