2.3 TUBING CONNECTIONS
1. Insert tubing through Coupling Nut. Tubing
should enter the smaller end of the Coupling Nut
first, orienting the larger opening of the Coupling
Nut toward the tubing end.
2a. For 1/4” OD tubing: Position the Female
Ferrule so that 1/4” to 3/8” (5-10 mm) of tubing
protrudes from the Female Ferrule. Orient the
raised collar of the Ferrule toward the Coupling
Nut (reference
Figure 4
).
2b. For 3/8” or 1/2” OD tubing: Position a Female
Ferrule about 1 inch (25 mm) from end of tubing.
Orient the raised collar of the Female Ferrule
toward the Coupling Nut. Then, insert the Male
Ferrule onto the end of the tube, pushing the
tube into the bottom of the groove in the Male
Ferrule. Then slide the Female Ferrule down
the tubing and with your fingers, press tightly
into the Male Ferrule (reference
Figure 5
).
3. Firmly hand tighten the Coupling Nut onto the
fitting.
Note:
Tightening with pliers may cause the Ferrules
to break.
