3. Install AccuCrimp tting fully into
tube end until ring engages the tting
tabs.
4. 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.
Note: Tabs will perfectly align the ring
over the tting's sealing barbs.
F2159 ttings are made from PPSU polymer.
Sioux Chief uses Accudel resin.
F2159 systems use a copper crimp ring to compress
around a tting.
Connection is made by positioning a crimp ring over
the tube and down to the tabs of the AccuCrimp tting
thereby positioning the ring perfectly over the sealing
barbs. Compress assembly with a properly calibrated
crimping tool.
