stainless nut.
For a leak in the pass-through fitting, which cannot be stopped by simply tightening the
nut, loosen the nut and slide it up the tube with a rocking motion to drag the Goretex
seal out of the nut. If the seal remains inside the fitting, it can be removed by carefully
“digging” it out with a sharp object, or alternatively, left in place. In the latter case, the
length of Goretex making up the replacement seal will have to be shorter than usual.
The replacement Goretex joint sealant (3/16" size with adhesive backing) comes in rolls
and should be cut as shown in the next figure, or can be obtained from the factory
already pre-cut. Wrap the seal around the tube in a helical fashion with the adhesive
side towards the tubing as also shown in the next figure, push the nut down over the
seal, and screw the nut onto the fitting. Do not tighten the nut up completely until the
unit is again reheated, then do so only enough to make the seal, leaving the maximum
amount of additional take-up available.

5.2.3 The Mixing Valves
The mixing valves are a PVDF union mettering type. These valves and the actuator have been
configured by the factory and require no adjustment. Adjustment of the valves or actuator may
alter the performance of the Fluidix unit or cause severe damage to components. Although no
adjustment is required the valves are to be hand tightened only. The mettering valves are fitted
with Chemraz O-rings. Contact the factory for O-ring seal replacement instructions.
