4.3 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 1).
2b. For 3/8” or 1/2” OD tubing: Position a Female Ferrule about one 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 2).
3. Firmly hand tighten the Coupling Nut onto the fitting. Note: Tightening with pliers
may cause the Ferrules to break.
A. USE ONLY LMI TUBING—ALWAYS use LMI supplied
tubing with your pump, as the tubing is specifically designed for
use with the pump fittings.

C. Before installation, all tubing must be cut with a clean square end.
D. Valve and head connections from the factory are capped or plugged to
retain pre-prime water. Remove and discard these caps or plugs before
connecting tubing.
