5.0 Tubing Connections

Use only LMI supplied tubing with your pump, as the tubing is
specifically designed for use with the pump fittings. Before
installation, all tubing must be cut with a clean square end.
DO NOT USE PLIERS OR PIPE WRENCH ON COUPLING NUTS
OR FITTINGS.
DO NOT REUSE FERRULES — USE ONLY NEW FERRULES.
Insert tubing through coupling nut. The tubing should enter the smaller
1.
end of the coupling nut first, orienting the larger opening of the coupling
nut toward the tubing end.
Position a female ferrule about 1 in (25 mm) from end of tubing. For 3/8
2.
in and 8 mm tubing, orient the raised collar of the female ferrule toward
the coupling nut.
Insert the male ferrule onto the end of the tube, pushing the tube
3.
into the bottom of the groove or base.
Slide the female ferrule down the tubing and with your fingers,
4.
press tightly into the male ferrule.
Firmly hand tighten the coupling nut onto the fitting.
