4.2 Fitting Assembly

HOME-FLEX® ttings achieve seal by compressing the tubing into the gasket (Figure 4.2). It is

critical that the cut end of the tubing is clean of

any burrs or jagged edges, and that there is no

debris on the tubing or gasket. A seal is achieved

with a good deal of force (Table 4.3). In the

absence of a torque wrench, the general guide-

line is to tighten with two wrenches (one holding

the tting in place, the other turning the ange

nut counter-clockwise) until the nut will no lon-

ger turn and only 2-3 threads are showing.

Note: The gasket can only be used once. Once it has been compressed (Figure 4.2) during

the assembly process, it cannot be reused. A new gasket must be installed in the tting

Note: Not all titngs include an o-ring (Figure 4.2-3).The o-ring does not function as a gas

sealing mechanism in the tting assembly. The o-ring keeps moisture and corrosives out

of the area between the tubing and tting ange. If the o-ring is misplaced or not present

and there is risk of outside moisture or contaminants entering the assembly, wrap with the

assembly with self-bonding silicone tape from the tubing jacket to the end of the nut ange.
